Wrapped Aluminium Bimetal Bearing Bushes Tin-Plated AlSn20Cu Anti-corrosion
1. Product Description
Wrapped Aluminium Bimetal Bearing Bushes Tin-Plated AlSn20Cu Anti-corrosion is a bearing with high percentage of tin and aluminum composition,with steel as back and press AlSn20Cu as lining.It is widely applied under high speed and low load. To effectively decrease abrasion, its alloy surface can be machined with oil grooves for easier oil storage.
