Product Introduction

Aluminum bushing, steel bronze bimetal bushes, composite bush has a combination of high strength, load-bearing capacity, and the advantages of good wear resistance. Particularly suited to medium-speed and low-speed high-contained set and so on.


High tin aluminum bearing, is based on steel matrix, the surface of roller AISn20Cu material products. This product has secondary fatigue strength and bearing capacity, good corrosion resistance, good sliding properties, etc. This product is used for medium and small power of internal combustion engine bearing shell machine collar axis, the train engine bearings, air, is replacing babbitt novel products.
