PTFE Sliding Bushing

PTFE Sliding Bushing

1. PTFE Sliding Bushing is a self-lubricating multi layer bearing consisting of tin-coated steel, a middle layer of sintered bronze and an inner layer, sliding surface, of PTFE. 

2. PTFE Sliding Bushing is mainly suitable for rotating and oscillating movements and applications with frequent starts and stops. 

3. The friction value is very low which enables SF-1 bearings to be used without lubrication. 

4. PTFE Sliding Bushing can also be used in oil or water since the bearings are highly corrosion resistant. is a self-lubricating multi layer bearing consisting of tin-coated steel, a middle layer of sintered bronze and an inner layer, sliding surface, of PTFE.
