Bimetal Bushes,
Bimetal bushings consist of two distinct metal layers: the primary layer is typically made of steel, while the secondary layer is usually a copper alloy. This copper alloy acts as an internal lining when paired with the steel layer. Additionally, some sizes of these bushings feature an external re-lubrication hole or groove to facilitate maintenance.

Bimetal Plain Bearings to Standard SAE 792
Overview
Bimetal plain bearings to standard SAE 792 are composite bearing materials that consist of a steel backing and a bronze overlay. These bearings are designed to handle high specific loads, particularly in applications involving oscillating motion and low frequency. They are known for their high load capacity, excellent resistance to fatigue at higher temperatures, and suitability for rough operating conditions.
Composition and Structure
- Steel Backing: Provides structural support and high load-bearing capacity.
- Bronze Overlay: Typically leaded bronze, which offers good wear resistance and a low coefficient of friction.
Manufacturing Process
Bimetal bearings are produced using a special sintering process. This involves bonding a layer of bronze to a steel backing, creating a durable and efficient bearing material. The sintering process ensures a strong bond between the two metals, enhancing the bearing’s performance under high pressure and heat.
Advantages
- High Load Capacity: Suitable for applications with high specific loads and oscillating movements.
- Wear Resistance: Excellent wear resistance, even under heavy loads and varying temperatures.
- Fatigue Strength: Very good resistance to fatigue at higher temperatures, making them ideal for demanding applications.
- Versatility: Can be used in various industrial applications, including pumps, compressors, engines, and heavy-duty machinery.
- Maintenance-Free Operation: Typically requires no lubrication, reducing maintenance costs and downtime.
- Low Coefficient of Friction: Ensures efficient operation and reduces energy loss.
- Corrosion Resistance: Highly resistant to corrosion, extending the lifespan of the bearing and the machinery it is used in.
- Shock and Vibration Absorption: Helps reduce noise and improve the comfort of machinery operators.
- Dimensional Accuracy: Does not absorb water, ensuring maximum dimensional accuracy.
- Environmental Suitability: Can be used in dusty, corrosive, and even radioactive environments, as well as in seawater.
Applications
Bimetal bearings are widely used in:
- Automobile Engines and Chassis: For their durability and ability to handle high loads and temperatures.
- Motorcycle Clutches: Due to their wear resistance and low friction.
- Gear Pumps and Lifting Equipment: For their high load capacity and fatigue strength.
- Heavy-Duty Machinery: Ideal for machinery subject to constant wear and tear, such as in industrial applications.
Technical Specifications
- Operating Temperature: -40 to 482°F (-40 to 250°C).
- Tensile Strength: 20305 to 43511 psi (14290 to 30622 m H2O).
- Material Composition: Approximately 80% Cu, 10% Pb, and 10% Sn.
Conclusion
Bimetal plain bearings to standard SAE 792 offer a robust and versatile solution for various industrial applications. Their high load capacity, excellent wear resistance, and ability to operate under harsh conditions make them a valuable component in maintaining the efficiency and longevity of machinery

Standard sizes have grease grooves on the work surface. For standard bearings, the steel base is usually copper plated to improve corrosion resistance. The lead bronze layer allows these bearings to be used with relatively long lubrication intervals.
Bimetallic bearings can be fabricated with a thicker layer of lead bronze for applications where the bearing must be machined after installation. The layer material can be tailored to the specific needs of a particular application.
