Plain Bearings, Self-lubricating Bushings Manufacturer
JF-700 Bimetal Buahing Bearings
JF-700 bi-metal bushing is backing on low carbon steel, sintered with CuPb30 bronze powder. It has good performance in shaft seizing resistance and cover up alien substance due to the high lead content. When soft alloy is plated on the bushing surface, it can be applied under high speed and middle load working situation, just like engine main bearing, connect-rod bushing, rocket arm bushing and oil pump side plate. CuPb30 Bimetal Tractor and Harvester Bushing: CuPb30 Bimetal Tractor and Harvester Bushings are a specific type of bimetal bushing that utilizes a composite structure. This structure includes a steel backing layer for strength and a sintered CuPb30 (Copper-Lead alloy) lining layer for superior anti-friction properties.
