Let is take a look at the basic concept of composite bimetal bearing

Author:admin   Date:2022-11-25
Composite bimetallic bearing is one of oil-free lubrication bearings. The product is made of high-quality low-carbon steel back as the base, sintered lead tin bronze alloy on the surface, and rolled into a bimetallic strip of copper and steel after several times of high temperature sintering and compact rolling. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is especially suitable for heavy load, low speed, reciprocating or swinging and other occasions where it is difficult to lubricate and form oil film, and is not afraid of water erosion and erosion of other acid solutions.

Since the base plate is stably made of low carbon steel, the processing accuracy of the outer diameter of the shaft sleeve is guaranteed, and after the product is installed into the seat hole, it does not need to be fixed by screws, and the interference fit can prevent it from going out of the outer circle. The change of the chemical composition of the alloy layer on the inner surface can meet the requirements of different bearing pressures, different operating temperatures and different sliding speeds. The oil grooves and oil cavities of different structures designed for the friction surface in production can meet the requirements of different oil filling methods and can prevent shaft seizure.

The composite bimetal bearing has the advantages of good wear resistance, especially suitable for medium speed, medium load, low speed, high load and other occasions. Through special technology, various oil grooves, oil cavities and oil holes can be machined on the friction surface to adapt to the use under different lubrication conditions. The products are mainly used in heavy truck balance axle bushings and gaskets; Automobile engine, chassis, motorcycle clutch, gear pump friction plate, lifting equipment and other fields.
