Because of the working environment and other reasons, the bushings used on the hoist need special requirements. According to different requirements, our company produces high-strength brass self-lubricating copper sleeves, which can be significantly improved. Its hardness and load-bearing performance are higher than ordinary bronze in the case of low speed and heavy load.
The alloy copper sleeves with ZQSN6-6-3, ZCuSn10Pb1, ZCuSn555 tin bronze, ZCuPb10Sn10 lead bronze, ZCuAl9Fe4 aluminum bronze, etc. have high mechanical properties, wear-reducing properties and corrosion resistance, small shrinkage coefficient and no magnetic properties. , Tin bronze copper sleeve is very resistant to corrosion in the atmosphere, sea water, fresh water and steam.
