POM based sliding bearing also called DX bushing, boundary lubrication bearing,SF-2 oilless bearing,dry bearing, DX bearing and POM lined plain dry bush. It has similar material structure with DU bushing. The difference is the layer with POM coated.
欧冠投注网These materiais consist of metal backing bonded to a porous bronze sintered layer with PTFE based polymer bearing layer.The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bonding between the backing and the bearing lining,the PTFE based polymer offers exceptional low friction even under dry condition.

3. Steel backing 0.4~2.2mm.
4. Copper plating 0.008mm.
Suitable for rotating and oscillating movement
Good damping performance, good resistance to shock loads
Less maintenance requirements due to the long re-lubrication intervals
Lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling
