Bimetal Bushings Manufacturers – Select High-Quality Bushings Bearing at a Good Price
Our company specializes in manufacturing high-quality bimetal bushings that offer excellent performance and value. These bimetal bushings are a type of lubricating bearing that combines the advantages of metal bearings and self-lubricating bearings.
Our bimetal bushings are made to the standard SAE 792, which consists of a steel backing and a leaded bronze overlay. The bronze overlay is composed of CuPb10Sn10, a lead bronze alloy that exhibits good lubricity, wear resistance, and corrosion resistance. These properties make it suitable for various applications, including sliding bearings subjected to high surface pressure, rolling and rolling bearings for vehicles, parts subject to impact with peak loads of up to 60MPa, bimetallic shingles for internal combustion engines with maximum peak values of 100MPa, piston pin bushings, and friction plates.
At www.bronzelube.com, we take pride in being a professional supplier of bimetal bearings. We offer a wide range of sizes, forms, and materials in both monometallic and bimetallic bearings. Our bimetal bearings are self-lubricating and have a high load-carrying capacity, superior wear resistance, and a long service life.
We have customers from all around the world who have become long-term clients due to our competitive prices, efficient pre and after-sales service, innovative team, and continuous additions to our product line. We also provide the option for customized products tailored to meet specific business needs.
Our bimetal bushings are manufactured with high-quality low-carbon steel substrates and sintered copper alloy surfaces that offer low friction characteristics. The copper alloy wear layer includes materials such as CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30, AlSn20Cu, and CuSn8Ni. The surfaces can be processed with various types of sump holes and oil holes to suit different lubrication requirements.
These bimetal bushings find applications in a wide range of industries, including automobile engines, engineering and agriculture machinery, and heavy-duty construction machinery.
Here are some performance data for our bimetal bushings:
Max dynamic Load P: 140N/mm²
Max line speed V (Grease lubrication): 2.5m/s
Max PV value (Grease lubrication): 2.8N/mm²·m/s
Friction coef μ (Grease lubrication): 0.05~0.15
Max line speed V (Oil lubrication): 5m/s
Max PV value (Oil lubrication): 10N/mm²·m/s
Friction coef μ (Oil lubrication): 0.04~0.12
Max Working temperature (Grease lubrication): 150℃
Max Working temperature (Oil lubrication): 250℃
We can also accommodate customers’ special requests beyond the specifications mentioned above.
For lead-free replacements of SAE 792 in bushing applications, we offer suitable alternatives as well.
Please visit our website, www.bronzelube.com, for more information on our bimetal bushings and to explore our comprehensive range of products.
Bimetal bushings with lower lead content, with the specific alloy CuSn10Pb5 being a consideration. These bushings, as you described, consist of a steel backing for mechanical strength and a sintered alloy layer, which provides self-lubricating properties and good wear resistance.
Your data suggests that these materials can bear static loads up to 250N/mm² and dynamic loads up to 140N/mm². They can operate within the temperature range of -40°C to +250°C, and are suitable for medium loads at medium to low speeds. Additional enhancements, like oil grooves or oil deposits, can further improve the lubricating performance.
You’ve also mentioned that these bushings are suitable for dusty environments or locations where contaminants may be present, due to the alloy’s good embeddability. Potential applications include connection rods, undercarriage rollers, hydraulic cylinder rod eyes, and various types of machinery in materials handling, agriculture, and forestry.
These lower lead bimetal bushings appear to be a viable option for replacing SAE 792 in some applications. It’s worth noting, however, that while the lead content is reduced, it is not completely eliminated. Therefore, these materials may still be subject to restrictions in certain jurisdictions or for specific applications due to health and environmental concerns.
When selecting a lead-free or lower-lead alternative for bushings, it’s important to balance the specific needs of the application, including load, speed, operating environment, and regulatory constraints, with the properties of the available materials.
SAE 792 Bimetal Bush
It is SAE792 lead bronze, corresponding to the national standard CuPb10Sn10.
SAE792 lead bronze has good lubricity, wear resistance, and corrosion resistance, and is suitable for use as a bimetallic casting material. Such as sliding bearings with high surface pressure and side pressure, such as rolling and rolling, bearings for vehicles, parts subject to impact with a peak load of 60MPa, and bimetallic shingles for internal combustion engines with a maximum peak value of 100MPa, as well as piston pin bushings, friction plates, etc.

Professional Bimetal Bearings Supplier – www.bronzelube.com
Bimetal bushing bearings are a new type of lubricating bearing that combines the advantages of metal bearings and self-lubricating bearings.
We offer a broad range of sizes, forms, and materials in monometallic and bimetallic bearings.
Bimetal bearings are self-lubricating. They have a high tendency to tolerate high weights and, due to their wear resistance and high potential, leave the other bushings behind.
For all your bimetallic bearing needs, bronzelube.com is the best place to go. We have customers all over the world, and our customers have become long-term customers due to our low prices and efficient pre and after-sales service, creative staff, and cutting-edge additions to our product line. You can also order products that are specially tailored to your business needs.
Bimetallic composite bearings to the high-quality low-carbon steel substrate, the surface of the sintered copper alloy having a low friction characteristic (CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30, AlSn20Cu, CuSn8Ni) as bearing wear layer, copper alloy surface may need to use conditions processing various types of sump hole, oil hole, so as to not be suitable for continuous refueling or difficult situations.
