High load capacity and maintenance-free

 

PTFE bearings are ideal for applications with high loads and moderate speeds. The distinctive feature of these plain bearings is that they are maintenance-free. PTFE bearings are produced according to ISO 3547.

 

 coated bushings

 

Materials

 

PTFE bearings are made with a steel or bronze backing as standard. A stainless steel backing is available on request. A sintered bronze layer is applied to the backing. This layer is provided with a PTFE-based self-lubricating lead-free sliding surface. The bronze intermediate layer ensures efficient heat dissipation and makes for a strong joint between the backing and the sliding surface. The steel backing has a layer of tin to prevent corrosion.

 

Lubrication

 

During a short run-in period, part of the run-in layer, the PTFE mixture, is transferred to the counter-material. During the run-in period of the PTFE bearing, the bearing surface usually takes on a gray/green color. The characteristic low friction and wear values are obtained at the end of the run-in period. Adding oil or other non-corrosive fluids can enhance the bearing's performance.

 

Applications

 

PTFE bearings are best suited to applications with high loads and requiring self-lubricating operation. Common applications are:

 

  • Elevators
  • Hydraulics
  • Textile machines
  • Butterfly valves
  • Consumer electronics
