Maintenance-Free Bearings is one of the most common self-lubricating bearings. It is based on steel plate with spherical bronze powder sintered inside it.PTFE and Pb mixtrue are rolled on the surface layer. According to requirement,such bearing can be coted with different coatings.Maintenance-Free Bearings has good lubrication .Maintenance-free bearings are widely used in various aspects.
1.Can be applied to where oil is difficult to be applied.
2.It's very light compared with other bearings.
3.The coating can be adjusted according to requirement.
4.Has long life and low friction as well as low pollution.
5.Mature technology made Maintenance-Free Dry Bearings very cheap
