Bimetal Thrust Washer Bearing for Automobile Engine Con Rods

In automotive engines and industrial machinery, components that manage friction and axial loads are essential to ensure long-term durability and performance. The bimetal thrust washer bearing is a key part used in the connecting rods (con rods) of engines, designed to handle axial pressure while reducing surface wear between moving parts. Its structure and material make it highly suitable for harsh mechanical environments such as transmission systems, construction equipment, and agricultural machinery.

Material and Structure

This bearing features a dual-metal composition. The base is made from low carbon steel, providing strength and structural stability. The working surface is overlaid with a tin-lead-bronze alloy (CuSn10Pb10), offering excellent anti-friction characteristics and strong load resistance.

· Backing: Low carbon steel

· Alloy surface: CuSn10Pb10 (tin-lead-bronze)

· Surface hardness: HB 60–90

The bimetal construction allows the washer to maintain a high degree of conformity and resistance to fatigue, making it a reliable solution in demanding operating conditions.

Performance Specifications

The thrust washer is engineered to withstand considerable mechanical and thermal stress:

· Maximum load capacity: 150 N/mm²

· Maximum working temperature:

  · Grease lubrication: up to 150°C

  · Oil lubrication: up to 250°C

These ratings demonstrate its ability to operate efficiently under high-speed and high-temperature engine conditions, making it suitable for internal combustion engines and gear systems.

Advantages of Bimetal Thrust Washer Bearings

Bimetal thrust washer bearings combine mechanical strength with low friction performance. The steel backing offers rigidity, while the bronze alloy provides excellent wear resistance and load distribution. This makes the product suitable for long-term use without frequent maintenance or replacement.

They are especially valuable in engine rebuilds, OEM production lines, and heavy equipment maintenance, where component reliability can directly impact overall system performance.

The bimetal thrust washer bearing is a proven solution for axial load management in engine con rods and industrial machinery. With its robust dual-metal construction, high-temperature resistance, and compatibility with both grease and oil lubrication systems, it meets the demands of modern mechanical applications. For manufacturers, mechanics, and machine builders seeking high-quality, performance-tested components, this washer bearing offers a practical balance of durability and cost-efficiency.
