Description

Bushing(bearing), a type of plain bearing

Bushings are akin to thin tubes most commonly used for machinery with rotating or sliding shafts to improve efficiency and reduce vibration and noise.In the excavator cylinder, bushing is embedded in the cylinder head, and it plays the role of supporting the piston rod.

The key benefits of Oilless Bushings are
High precision
High speed
Low noise
Wear resistance

SF-1 Oilless Bushing material structure:
1. Mixture of PTFE and Pb lead 0.01 – 0.03mm for wear resistance.
2. Porous bronze powder 0.2 – 0.3mm for lubrication performance and wear resistance.
3. Steel backing 0.7 – 2.3mm for lubrication performance and facilitation of heat transfer.
4. Electroplated coating: 0.005mm of tin coating or 0.008mm of copper coating.
