PVB02系列边界润滑轴承

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.

Material Structure:

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.

1. POM with lead 0.3~0.5mm.

2. Porous bronze 0.2~0.3mm.

3. Steel backing 0.4~2.2mm.

4. Copper plating 0.008mm.


Bearing Design

Depending upon application requirements, PVB02 Series self lubricating bearing can be produced in many shapes and sizes from inner diameters 10mm to more than 300mm.

Advantages

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
