DX/SF-2 boundary lubrication bearing is based on a composite material with 3 firmly bounded layer: steel as backing, sintered porous bronze powder as interlayer and modified POM as lining layer.

The lining layer can be made without Pb, which is used in the field where environment protection is requied.

This boundary lubrication bearings are widely used in auto chassis, forging machine, metallurgical and mining equipment, construction machinery, power station, strip rolling industries, textile machines, piston pumps, steering system of automobile, etc.
