Copper Alloy CuZn31Si Wrapped Bronze Bearing Bushes Low Running Velocity
It is made of copper alloy CuZn31Si that is of higher density. Its surface can be punched with oil sockets or grooves, which are preserved for oil saving. It has better anti-fatigue and load, anti-erosion and anti-silicon abrasion capacity. The products are widely applied in conditions of heavier load but low running velocity, such as on agricultural, building and engineering machines, etc.
