Less maintenance or even maintenance-free.

JDB bearing

Under the conditions of high temperature of 300 degrees, we generally choose high-strength brass as the base of copper graphite bearings. If there is contact with water or other corrosive liquids in the working conditions, we should find more according to the specific conditions. A copper alloy substrate that satisfies working conditions, such as tin bronze, aluminum bronze, lead bronze, and the like.
