Product Description

Steel Backing,AlSn20Cu1,Metallic marginal-lubricating bearings CSB-J20


Viiplus Metallic marginal-lubricating bearings Online Bearing Bushing Solutions.


AlSn20Cu Bimetal Bearings is backed with high quality low carbon steel with Aluminum-Tin alloy (AlSn20Cu) sintered on its surface. To effectively decrease abrasion, AlSn20Cu Bimetal Bearings' alloy surface can be machined with oil grooves for easier oil storage. When necessary, an erosion protection coating can be plated on the steel back. In common application, AlSn20Cu Bimetal Bearings is used to make wrapped bushes, thrust washer and bushes on connecting rod level of gas engine, etc.




The material has good oil corrosion resistance feature. It is smooth and has outstanding embeddability and antiseizure performance. The working surface is not needed to be coated. It is suitable to be used to mate with soft shaft. The OD of the bearing is machined to a high precision grade and ID is machinable after assembling. This material is conformed to the ROHS regulation 2000/53/EC.
