Self-Lubricating Bearings: Reliable Self-Lubricating Bearings from Huaxiao
Self-Lubricating Bearings are oil-impregnated sintered bronze or iron parts that lubricate themselves for life—ideal where maintenance is hard or impossible.

How Self-Lubricating Bearings Works
Porous PM bushings are vacuum-impregnated with oil; capillary action repositions oil to the surface under load, then wicks it back when at rest.
Sintered vs. Solid Bearings
Sintered self-lubricating bearings need no external oil; solid bearings rely on grease and housing supply.
Materials
- Bronze PM—general-purpose bushings
