Metal bearing bushings reduce friction between components and lubricate them

Author:admin   Date:2023-06-01
Metal bearing bushings reduce friction between components and lubricate them. The material is normally copper-lead alloy. It is resistant to abrasion and corrosion. It is also self-lubricating.
To form the hybrid workpiece successfully, different heating strategies were investigated. The material distribution in longitudinal cross-section as well as the forming behavior were assessed.
Product Description
Bi-metal sliding bearings combine steel backed with sintered lead bronze layer and can be used under oil or grease lubrication. This material has very good fatigue strength and abrasion resistance. It is suitable for middle load, high speed and impact loading. It can also be operated in harsh environment. It is used for gear bushing, trunnion shaft bushings, brake caliper bushes, king-pin bushings, tailgate pivots and mechanical handling and lifting equipment, hydraulic motors & pumps, and agricultural machinery.
Feature
In this context, tailored forming technology can be applied, where the aluminum is heated inductively by the skin-effect and the steel is heated with heat dissipated from the outer part of the hybrid workpiece. This allows the material to be forged at its typical forming temperatures without affecting the thermal expansion of the aluminum.
Application
It has excellent fatigue resistance, load capacity and anti-corrosion performance, widely used in water turbines, vane controls, injection molding machinery, paper production equipment, furnace expansion plates, automotive transmission, lifting chain linkage, etc.
China sleeve bushing manufacturers with more than 150 million sets of production capacity and one automatic sintering line, relying on the Research Institute and colleges and universities, constantly develop self-lubricating bearing products adapted to different working conditions and various mechanical fields. Products are sold in more than 40 countries and regions at home and abroad. Our product range includes cylindrical, flanged and sleeve bimetal bearings. We can also produce wrapped bushings, thrust washers and strips.
Packaging
The WZB Bimetal Bushing are packaged in bags and rolls to avoid damage during transportation. They are suitable for middle speed and high load bushes, washer and connecting rod bearing in internal combustion engine used in mechanical equipment. They have very good resistance to fatigue strength and shock. They require initial greasing when installed and periodic lubrication afterwards. They are also a good choice for many automotive applications, such as power steering cylinders and steering gear thrust washers.
