product description
JDB-600 precision-machined copper alloy bushings provide a simple and economical bearing application, with high load-bearing, good corrosion resistance, and arbitrary size processing.
At the same time, Dingyue can provide copper alloys of different grades according to different working conditions, and process different forms according to the requirements. It has higher dimensional accuracy than rolled copper bearings.
