Application characteristics：

Jf-800 bimetal bearing is a steel copper alloy product with low carbon steel plate as the base material and cupb10sn10 or cusn6zn6pb3 material sintered on the surface. This product is one of the most powerful bearing capacity in the double alloy bearing. It is used in the balance bridge bush of heavy truck. It is a kind of widely used high load and low speed moving bearing.
