PTFE bearings High load and maintenance-Free
2019-06-25
PTFE bearings are ideal for applications with high loads and moderate speeds. They are characterized by being maintenance-free.
Advantages
Main advantages of PTFE bearings include:
• Self-lubricating
• Maintenance-free
• High load
• Low friction coefficient
• Minimal bearing play
• Operating temperature up to 250°C
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 unleaded 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.
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
Lubrication
During a short run-in period, part of the run-in layer, the PTFE mixture, is transferred to the counter- material. During this run-in period the bearing surface usually takes on a gray/green color. The characteristic low friction and wearing values are obtained at the end of the run-in period.
Adding oil or other non-corrosive fluids can enhance the bearing's performance.
