1) Description of Copper Bushing
A brass bushing set in a mechanical bore slot to support a rotating shaft and reduce the coefficient of friction.
2) Feature and Advantage of Copper Bushing
a) Self-lubricating: Some copper alloys contain graphite, no additional lubricant is required.
b) High load carrying capacity: Suitable for heavy load and low speed working conditions.
c) High accuracy: customized tolerances to match shaft diameter.
d) Reduced vibration and noise: cushions the impact between shaft and housing.
e) High compatibility: can be used with a wide range of metals.
3) Application of Copper Bushing
Construction machinery (e.g. excavator boom hinge points), machine tool guideways, etc.
