Self-lubricating - when in motion oil rises to the surface for lubrication and restores itself when at rest.

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.

Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10F to 220F.

RoHS, REACH, DFARS compliant

· Do not need or only very little machining

· High usage rate of material(more than 95%)

· Parts size consistency is good and stable. The precision can reach 0.01mm.

· The material composition can be adjusted according to the customers’requirement of the parts performance.

· Do the treatment on the surface of the parts according to customers’ requirement to improve the strength and hardness.

· Due to the die forming, we can customize the complex shape or special profiled parts which other machining can not do.

· Because suitable for mass production, the production efficiency is high and the cost is lower than machining.
