Hydrodynamic Composite Bearings
Steel Bronze Powder with PEEK/PTFE Marginal Bearings, provides maintenance-free operating, Temperature be allowance from -150 until +250°C, operate satisfactorily without lubrication under lieght duty and low speed, high static and dynamic load
Steel + Bronze Powder + PEEK/PTFE
1 . VSB-30 provides maintenance-free operation
2 . Operate satisfectorily without lubrication under light duty and low speed
3 . VSB-30 has a high PV capability under high temperature
4 . Temperature allowance is from -150℃-+250℃
5 . Good chemical resistance
6 . High static and dynamic load capacity
7 . No water absorption
8 . Suitable for rotating , oscillating , reciprocating and sliding movement .
1.PEEK/PTFE 0.30~0.50mm. It has high wear resistance and low friction even only minute of lubricant are supplied. The bearing surface carries a pattern of circular indents which will be filled with grease on assembly of the bearing.
2.Bronze layer 0.20~0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3.Steel backing.Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
