基本特性 Basic characteristics
JDB-650 copper-based solid mosaic self-lubricating bearings, combined with copper alloy (ZCuZn24Al6) wear resistance and self-lubricating properties of solid lubricants, so that in the process without refueling maintenance. Products are widely used in high load, intermittent or swing movement, such as steam locomotive production lines, water turbines, reservoir work / accident doors, plastic machinery. Depending on the operating conditions, various types of copper alloys may be provided.
