DJA MOND multilayer POM relubricable bushings

POM multilayer bushings are three-layer plain bearings consisting of a steel backing, a porous bronze intermediate layer and a POM or composite PEEK sliding layer. Pre-lubricated and designed for low maintenance, they are suitable for applications involving shock loads and high sliding speeds. POM plain bearings require only a small amount of lubricant to provide reliable long-term performance. DJA MOND PT..RK multilayer POM bushings offer low wear, excellent anti-friction performance and high PV values. Compared with other relubricable bushings (case-hardened, bronze wrapped or bimetallic bushings), POM multilayer bushings are the ideal solution where minimal lubrication and good shock-load capability are more important than maximum load capacity or extreme temperature resistance.

The backing of these POM plain bearings is manufactured from low-carbon steel and coated with a 2 μm copper layer or alternative protective treatment. A sintered porous bronze layer is then applied, providing support for the POM or composite PEEK sliding layer with lubricant reservoirs. Initial greasing is required, while periodic relubrication is generally not necessary. However, continuous lubricant supply can further extend the service life of the bearing.
