China Supplier Bearing Track Roller - Welfine Metric Steel Ball Bearing – Welfine Detail:

After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation.

Bearing forms made to order: cylindrical bushes and flanged bushes with non-standard dimensions, spherical bearings, tubes and rod blanks, customized bearing designs. Self-lubricating – when in motion oil rises to the surface for lubrication and restores itself when at rest.

Maintenance-free bearing for general engineering applications.
