As a broader category, bronze bushings are desirable for their longevity and resistance properties, but there are still significant differences between cast bronze bushings and oil-impregnated bronze bushings. While similar in many ways, these component types are manufactured using completely different processes, and these processes lend themselves to different physical characteristics.
At Bunting Bearings, our oil-impregnated bronze bushings are made by the powder metal process while the cast variety are produced through more traditional machining methods. It’s important to understand how this distinction affects the final product, as one type may be more appropriate for your application than the other.
Oil-Impregnated Bronze Bushings
Oil-impregnated bronze bushings are characterized by their ability to self-lubricate. This effect is possible because of the powder metallurgy process:
- Bronze powder is gravity fed into a die set which is the desired bushing size. The powder is then pressed to connect the powder particles together.
- The powder particles in the part are then bonded together in a furnace. The furnace temperature is just high enough to bond the particles without melting the metal.
- This sintering procedure is the key to oil impregnation. Sintering, by nature, decreases the porosity of the product as it bonds the powder particles together, but it’s possible to control the degree to which this happens.
- For oil-impregnated bronze bushings, the final porosity is maintained at around 25%, meaning that there are still tiny, interconnected capillaries woven throughout the material.
- To finish the manufacturing process the bushing is then pressed through a calibration set of tools to the required tolerances. The bushing is then vacuum impregnated which forces oil into the interconnected porosity.
Benefits and Applications
Powder metallurgy was originally developed as a cost-effective alternative to standard machining and remains an extremely economical option. In most cases, it is one of the most efficient methods of high-volume production, which translates into cost savings on the consumer end. Oil impregnation also eliminates the need for lubricants and frequent maintenance.
Oil-impregnated bushings originated as an automotive component, however they are used in many other industries. Generally, our oil-impregnated bronze bushings are best-suited for low-to-moderate loads, but they do tolerate high-velocity loads better than many alternatives. They also function well across a wide temperature range of approximately 10–220°F, meaning that they are suitable for use in outdoor and industrial environments.
Cast Bronze Bushings
Unlike oil-impregnated bushings, cast bronze bushings are not formed from powder. Instead, they are formed from a solid or hollow bronze cast bar that undergoes machining processes designed to achieve a precise final shape.
- First bronze is continuous or centrifugally cast into a solid or hollow bar.
- Most modern manufacturers use a CNC lathe to cut the cast bar to its final size, although other machining techniques may be used for forming or finishing the bushing.
Benefits & Applications
Cast bronze bushings do not begin as a powder, so they are able to maintain a finer grain structure and therefore a higher degree of strength. In general, cast bronze bushings are also stronger, more durable, and more reliable under compressive force. This combination of properties makes cast bushings an ideal choice for applications involving heavier loads. A sintered bronze bushing of comparable size would simply be unable to withstand the same forces as a cast one.
Bunting Bearings’ Selection of Bronze Bushings

Bearings and bushings come in a range of sizes and can be made out of metal, plastic composites, or a combination of the two. This variety means you can find exactly what you need for a specific project; however, with so many choices, how do you decide the best option for you? Plastic and metal both have unique characteristics and advantages, and your choice will depend on the project, your budget, and more.
Plastic Bushings
Affordable and versatile, plastic bushings are used for many different industries, such as agricultural, medical, and machines, including fitness equipment, lawn mowers, food processing machinery, pumps, and valves. Because production of these bushings is fast and cost-effective, choosing plastic over metal could save you money depending on the type of plastic you choose.
Engineered plastic bushings have a predictable wear rate, meaning you can accurately calculate the service life for an application based on a tribological test database. You can accurately determine their service life span and replace them before they malfunction, knowing you used them exactly as long as you could. That means less guesswork, fewer errors, and more time and money saved.
Plastic bushings are corrosion and chemical resistant as well as self-lubricating—no grease required! If you think plastic is unable to stand up to heat, you might be surprised to learn these bushings can withstand temperatures up to 900°F for short periods. Over longer periods, they can perform in temperatures up to 482°F.
Bronze Bushings
With all the benefits of plastic, where does that leave metal? Bronze remains a popular choice for bushings because it’s available in so many alloys and compositions, expanding its reach into even more applications. A bronze bushing is harder and less likely to break or deform than those made of other materials.
Like plastic, bronze bushings are long-lasting and corrosion resistant. As noted above, their strength allows them to hold up under impact. One potential disadvantage is that metal requires a lubricant to reduce friction and prolong the bearing’s service life. Oil or grease must be applied at installation and during operation.
Still, the benefits may outweigh that small inconvenience. Bronze bushings are common in low-speed, high-load as well as high speed, low load industrial applications, including:
- Iron and steel manufacturing
- Food processing
- Valves
- Automobiles
Let’s take a closer look at two common bronze bushing materials:
- SAE841 Sintered Bronze:These oil-impregnated bronze bushings can be used with both high and low speeds, as well as high and low temperatures, depending upon the type of oil. SAE841 is also used for applications requiring food-grade quality.
- Cast Bronze:The extra corrosion resistance with these alloys (typically bronze with tin, aluminum, or silicon) makes it especially useful in wet environments.

Flanges feature a projecting rim over the edge of another part, a collar to secure connecting pieces together, or a ring to provide pressure to holds components in place. They enable part fabricators to customize the function of end products for customers.
Ultimately, flanges provide strength and stiffness at more vulnerable areas of a part and facilitate the connection of diverse components. They are also useful in mounting and positioning static items. When paired with bearings on the external housing of a device, flanges increase the ability of the end product to effectively handle radial and thrust loads.
Flanges are one of the most popular types of bearings requested by our clients at Bunting Bearings. This introduction to bronze flanged bearings will help readers understand what they are and what they can do for industrial manufacturing and assembly projects.
The Benefits of Bronze
Bronze alloys predominantly consist of copper and tin. Additional metals are added to the mix – i.e. aluminum, manganese, nickel, or zinc – to achieve the desired metallurgy. This results in a bronze material with ideal physical properties to suit the needs of the end application. For example, bronze can be tailored to have a specific physical appearance and offer better protection for end components against corrosion and surrounding conditions like moisture.
Bronze bearings and bushings are made to be rigid and tough. In comparison to those made of brass, bronze parts last longer and hold their shape better under repeated use. Bronze greatly improves resistance to:
- Impact
- Shock
- Corrosion
- Mechanical wear-and-tear
This means that bronze bearings last longer than their softer and more malleable brass counterparts. Bronze also causes less friction when brought in contact with other metal parts, which helps to extend the life of the bearing.
Applications and Advantages of Bronze Flanged Bearings
The versatility of bronze flanged bearings makes them an ideal fit for a number of industrial applications. Bronze flanged bearings are known for their low-maintenance durability. Heavy-duty industrial operations that rely on low-speed, high-load processes are particularly good candidates for bronze flange bearings, which hold up well under immense and repeated pressure.
Bronze flanged bearings are often found in equipment used in:
- Iron and steel manufacturing
- Food processing
- Injection molding
- Automotive equipment
- Earth movers
- Industrial pumps
The additional metal alloys that make up the bronze impart beneficial characteristics to the resulting material. Some of the common alloys used for bronze flanges include:
- Oil is infused into the alloy via powder metallurgy. Depending on its composition, SAE841 can accommodate for a wide range of speeds and temperature ranges. It is often used in food-grade applications.
- Aluminum, tin, and silicone. Marine manufacturers value the high corrosion-resistance of copper, but must alloy the copper with other materials to improve its strength. Copper alloyed with aluminum, tin, or silicone creates a bronze that enables manufacturers to create water-tight vessels without excessive weight.

With our recent purchase of six new Samsung CNC turning lathes with live tooling, Bunting Bearings is better equipped than ever to meet our customers’ needs. Two of these new additions were installed into a manual cell, while three were installed into a fully robotized cell, so they can be applied towards both low- and high-volume projects.
The sixth and largest machine of the group is the Samsung SL65/3200. It was installed to be used in conjunction with a VTL machine. We are excited about our new machining capabilities and what it means for our customers. Here is an overview of what CNC turning lathes do and the opportunities that our new equipment has created for our customers.
What Is a Live Tooling CNC Lathe?
A Computer Numerical Controlled (CNC) turning lathe is an automated tool that produces high-quality parts on a reliable, consistent basis. In a CNC lathe, the part itself spins while single-point cutters move across the part to create the desired shape, smoothness, and design; appropriate positioning of the part is provided by the main spindle’s ability to index precisely.
A programmer can design the part manually, or the part can be designed via computer-aided design (CAD) programs. From there, the computer directs the tool to make the appropriate cuts. After the design is perfected—which may require testing and adjustments to solidify the design—and production has begun, there is little need for constant supervision. The CNC lathe is highly precise and will continue making identical parts until all are complete. It can then be reprogrammed for a new part’s production. CAD parts can be saved and easily reapplied if a customer places another order for the same part in the future.
Our new live tooling CNC turning lathes give us a variety of options and functions with one simple set-up. When the part is stopped from spinning, driven tools (axial or radial) are able to create grooves and holes around the entire part as required. Without live tooling, we would have to remove the piece and go through additional steps to create grooves or holes, which adds on time, labor, and risks of error. Those live tooling capabilities within the CNC lathe are a major boost to productivity and accuracy.
What This Means for Our Customers
These new live tooling lathes are a worthwhile investment for Bunting Bearings, and a logical step in our growth process. We are now able to offer competitive pricing while producing parts with even greater precision. With fewer set-ups and less manual supervision, we can accomplish more in less time; our increased productivity means faster turnaround times and cost savings for you. With the two machines in the manual cell, we can maintain those quick turnarounds even on low volume runs.
As for the SL65, here are some of its specs, for insights to what it is capable of:
- 24” chuck
- 6” maximum swing
- 126” maximum turning length
- 5” diameter bar feed capacity
- 12-station heavy duty turret
It also allows us to produce parts with live tooling ranging from diameters of 3/8” to 10.” We are glad to speak with you about any special needs or custom orders you have in mind.

Our eco-friendly alloy C87850 ECO Bronze is RoHS compliant and meets the lead-free safe drinking water act. The main difference between our ECO BRONZE and other lead-free alternatives is that ECO BRONZE is a great bearing material.
Other materials compromise their bearing properties to become lead-free, but ECO BRONZE has proved to be as good as, and in some cases superior to, the leaded material it has replaced.
ECO BRONZE is probably the most tested lead-free bronze material to-date; Bunting Bearings and Chase Brass had this material arduously tested by various independent laboratories in the USA, and all came to the same conclusion: “it’s tough,” “non-galling,” “does not get brittle at high temperatures,” “superior impact and compressive strength,” and “a great bearing material. Eco Bronze has gained acceptability in the potable water pump industry as it is S3874 & AB1953 compliant, it’s also gained acceptance in other industries such as construction equipment, Wind tower, food processing, medical devices and many others due to its great bearing properties.
By incorporating ECO BRONZE into your manufacturing supply chain, your business can easily reach its sustainability goals. Being environmentally responsible is a goal that Bunting, Chase Brass and most of our customers share. By specifying a green product such as ECO BRONZE in lieu of a traditional leaded material you have taken a significant step forward. Furthermore, by leading your company with the procurement change your employees can take note and find additional ways for your business to decrease its environmental footprint. Selecting eco-friendly bronze products is just the start – how else does your facility plan to increase sustainability this year?
First, What is Tribology?
Tribology is the study of friction and wear on surfaces and materials that are in motion. Bearings are the perfect example of products that would require some background in tribology, since they are constantly rubbing against other items in their everyday function.
Bunting Bearings has always been at the forefront of bearing calculations including PV wear and friction data, and when we required independent verification on how effective a bearing material our new lead free ECO Bronze material was, we turned to the leading US tribology expert, Dr. Robert Adams.
Dr. Adams’ doctoral research was focused on characterizing plane bearing materials’ PV friction and wear performance profiles. Dr. Adams applied his knowledge to develop a tribometer that reduced the time needed to obtain reliable PV wear and friction test results. Dr. Adams’s company, Tribis Engineering Inc., is now finalizing all the PV data that will show that ECO Bronze is the first real cost competitive material to current leaded and lead free bronze bearing materials.
Bunting will be releasing tribological data on many of our bronze compounds in the near future.
There is not a single “best” bearing material and surface combination. Understanding how the various materials compare under these changing conditions makes it possible to select the “best” bearing material and surface combination for a particular application.
Tribo-spectrometry helps us to understand the particular friction and wear behavior of differing materials, and make the right choices for current needs.
British Petroleum and Royal Dutch Shell have declared that by 2050, most of the world’s energy needs will be met using alternative or clean energy. Renewable sources like natural gas, wind power and geothermal hot spots are valued for their clean properties.
Wind energy is fast growing in popularity and thanks to recent developments has experienced a surge in production volume, accompanied by a dip in the cost of set-up and expansion. And geothermal energy harvested from the heat of the Earth’s core is ever abundant and produces steam which in turn can drive turbine based devices to generate electricity.
Sustainable energy providers work to supply cities and operational activities like manufacturing with adequate clean power. To further accelerate the process of going green, vendors can use responsibly sourced or ‘sustainable’ materials to update infrastructure. This may include lead free bearings or items like reclaimed wood to replace traditional provisioning.
Bunting Bearings is a premiere name in the niche of environmentally friendly bearing solutions and supplies sustainable energy providers, marine, medical and other commercial markets with high quality components. Our eco-friendly alloys like the C87850 ECO Bronze, C95400 Aluminium- Bronze, C89835 Bismuth bronze are RoHS compliant and meet the lead-free safe drinking water act and are manufactured for use in heavy machinery and on rugged terrains.
By incorporating these materials into your manufacturing supply chain, your business can more easily reach sustainability goals. And by greening processes at the procurement level, employees can take note and find additional ways for the company to decrease its environmental footprint. Selecting eco-friendly industrial products is just the start – how else does your facility plan to increase sustainability this year? Let us know on Twitter.
When most people think of a powder metal bearing they think of Bronze normally made to the SAE841, MPIF CT-1000-K26 or similar specification, but they don’t think of powder metal for heavy loaded bearing applications. Many years ago Bunting pioneered BB16 as a heat treated iron copper material to handle these applications. It was branded as “The world’s best kept secret” but this is no longer true for some heavy industry users.
Typical uses of Bunting’s BB16 material are for off road equipment, earth moving equipment, escalators and the US Military. BB16 is heat treated to a Rockwell Hardness B scale (HRB) of 70 to increase its resistance to deformity under heavy loads. Similar to our standard Bronze bearing line, BB16 bearings are vacuum impregnated with Oil. However BB16 bearings contain extreme pressure oil which remains in the pores of the bearing to provide lubrication from the bearing to the shaft during operation. However, BB16 possesses a maximum load value of 8,000 psi (pounds per square inch), a maximum velocity value of 35 sfpm (surface feet per minute), and a maximum load-at-velocity (PV) value of 75,000. BB16 bearings can operate at temperatures ranging from -10 degrees F to 220 F (-12 degrees C to 104 C). If your application requires a self-lubricating bearing that can withstand high loads, then Buntings BB16 may be able to solve your problem.
Typically, the powdered metal process is used for high volume production of bronze bearings. However, we have found that many of our clients prefer powdered metal bearings, but do not necessarily need large volumes of product. That is where we step in.
We offer the advantages of powdered metal bearings for less traditional purposes. For example, if you need to produce prototypes and require an initial low volume of parts before full production, we can manufacture a powdered metal bearing for you, saving you money.
Here at Bunting Bearings, we offer clients a wide range of powdered metal self-lubricating solid and cored bars. Additionally, we stock over 200 different bars in bronze and iron copper, which can be customized to specific requirements. Whether your bearing needs to withstand 700 degrees F or requires strength of 22,000 psi, we will find the right powdered metal bearing to fit your needs. Specifically, we stock the standard SAE841, that has a working temperature range of 10 degrees F to 200 degrees F, and conforms to CT-1000-K26, the Dri Plane, which uses a proprietary compound for dry lubrication and high temperature applications, a military specification grade bronze, which conforms to CTG-1001-K23, and iron copper bars, which conform to SAE863 specifications.
The vast selection of bearings and products that we offer are available right now, in multiple sizes, and for a variety of uses. Our knowledgeable and experienced team is here to help answer any questions or concerns that you may have for your particular applications. Remember, we are one of the largest producers of bronze bearings in the U.S. and offer the highest quality products available.
