Structural properties and uses
JDB500#-1U precision-machined copper alloy bushing provides a simple and economical bearing application, with high bearing capacity, 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.
