Product Details

RCB-600 bronze bearings

Basic characteristics

This product is applied to HR630-HA centrifuge，it is installed in the bearing chamber of the centrifuge head, and the labyrinth seal is used to protect the bearing.This product uses ZCuSn10Pb1 cast copper alloy, alloy grade. It has high hardness, excellent wear resistance, is not easy to produce a seizure phenomenon, has good casting performance and cutting performance, and has good corrosion resistance in the atmosphere and fresh water. ZCuSn10Pb1 cast copper alloy can be used for wear-resistant parts working under high load (below 20MPa) and high sliding speed (8m / s), such as connecting rod, bushing, bush, gear, worm gear, etc.
