Igus RJUM-03-12, Bearing with 21.8mm Outside Diameter

Self Compensating,Uses a spherical area on the outer casing for self adjustment. Reductions in the load bearing capacity due to the self-adjusting function are thus avoided, because the shaft is always supported on the entire projected surface. Replacement liners are simply pushed into the aluminium housings.

Self-Lubricating Bushes - Drylin™

Drylin™ bearings are manufactured from high performance polymers. They run without lubrication and require no maintenance. They consist of a polymer liner located in an aluminium housing. Both standard and self-compensating styles are available in closed and split configurations. Features include very low friction, suitability for high speed and acceleration use, high load bearing capacity and self-wiping design. The bearings run on aluminium, steel and ceramic shafts.
