The AlSn20Cu1 Marginal Lubricating Metal Sleeve Bearing CSB-J20 is a precision-engineered bearing designed to excel in applications where lubrication is challenging or limited. This bearing features a metal sleeve made of the AlSn20Cu1 alloy, which offers exceptional strength, corrosion resistance, and wear resistance.
The marginal lubricating design of the CSB-J20 bearing ensures smooth and reliable operation even in conditions where external lubrication is not always feasible. The AlSn20Cu1 alloy, with its inherent lubricating properties, provides a low-friction surface that reduces wear and extends the bearing's lifespan.
The CSB-J20 bearing is well-suited for use in various industries, including machinery, automotive, and aerospace, where its ability to self-lubricate and withstand high loads and temperatures is highly valued. Its robust construction and precision manufacturing ensure reliable performance even under the most demanding operating conditions.
Wh it's in high-speed rotating equipment or heavy-duty industrial machinery, the AlSn20Cu1 Marginal Lubricating Metal Sleeve Bearing CSB-J20 offers a robust and long-lasting solution for lubrication-challenged applications.
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.
Features
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.
