The POM-based sleeve bearing, also called DX bushing, boundary lubricated bearing, oil-free bearing, dry bearing, DX bearing and POM coated dry sleeve. It has a similar material structure with dowels. The difference lies in the POM coated layer.
Yellow POM composite bushing is a standard item of our company. This type self-lubricating bearing has same material structure with other dx bushing.
1. POM 0.3~0.5mm.
2. Porous bronze 0.2~0.3mm.
3. Steel backing 0.4~2.2mm.
4. Copper plating 0.008mm.
