S-JCB Casting Bronze Bush

S-JCB Machined Casting Bronze Bush Bearing 

is manufactured using high tensile manganese bronze plugged without solid lubricants. Basic bronze alloy material is CuZn25Al6Fe3Mn3, we also provide widely optional choice from CuSn5Pb5Zn5, CuAl10Fe5Ni5, CuSn12, CuPb24 and other standards materials.We also have the capability to develop these bushes and plates as per any specifications of our clients.


S-JCB is in bronze base made by precision tooling.There is no solid lubricants plugged,so generally it has oil grooves inner the wall of bushing.Bronze material mainly in tin bronze or lead bronze.
