Hoisting Machinery Centrifugal Casting Bronze Sleeve Bearings
1. Product Description
Centrifugal Casting Bronze Sleeve Bearings With Oil Grooves Brass Bushings based on high-strength brass lubricated by the addition of oil in the groove, which has the same performance as the tin bronze bushing but has a much higher hardness, the service life for low speed application is twice that of the tin bronze bushing. It can be used under heavy load conditions.According to different customer requirements, according to ASTM, DIN, BS, UNS, SAE etc.bushing and China GB standard production of all kinds of bronze, brass bushing, plate and rod products.All products are made of electrolytic copper by centrifugal casting, continuous casting and extrusion sliding bearings.
