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.
Whether 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.
