JF-750双金属轴承

JF-750 lead-free bimetal bearing is an environment-friendly bimetal bearing. It is a steel-copper alloy product with low carbon steel plate as the base and CuSn6.5P0.1 material sintered on the surface. The product has high fatigue strength and bearing capacity, good sliding performance, and can replace lead-containing bimetallic bearings or copper sleeves in many occasions.
