E93 Brief Description

E93 is a high-density special copper bearing alloy as a matrix material CuSn rolled into having a carrying capacity, good wear resistance characteristics. Based on the good performance of copper easy processing and advanced tooling, E93 bearing surface of the strip can be processed to adapt to a variety of working conditions of oil pockets (standard products for the diamond oil hole), tank, so that the bearing can be stored in use a lot of grease, oil film at the beginning of work, to reduce the coefficient of friction, the work to extend the refueling interval period, effectively improve the bearing life. Compared with the traditional copper sleeve.
