Product
JDB-650 copper based solid inlaid self-lubricating bearing
Description
Basic characteristics
Jdb-650 copper based solid inlaid self-lubricating bearing combines the wear resistance of copper alloy (zcuzn24al6) and the self-lubricating performance of solid lubricant, which makes it unnecessary to use
Refueling maintenance. The products are widely used in high load, intermittent or swing motion, such as production line of steam locomotive, water turbine, reservoir working / emergency gate, plastic machinery, etc. According to
The working condition can provide various types of copper alloy.
