The product is a seamless bushing with uniformly distributed conical blind holes on its inner wall.

A natural lubricating oil wedge is formed during the grinding process of the inner hole, ensuring rapid oil film formation during startup.

The honeycomb structure provides 3-5 times more oil storage capacity than conventional grease grooves, enabling long-term maintenance-free operation.

The uniform honeycomb pattern with fixed circumferential spacing ensures full oil coverage across the inner surface with minimal rotation, eliminating lubrication dead zones.

The honeycomb skeleton significantly enhances load-bearing capacity and extends the bushing’s service life.
