PTFE Friction Bearings

An important prerequisite for Friction bearings (plain bearings) is that they work reliably over a long period of time and do not fail even under low-lube or dry running conditions.
Friction bearings (plain bearings) made of Moldflon TM or highly wear-resistant PTFE compounds are the solution from ElringKlinger Engineered Plastics.

They are particularly suitable for applications involving high p•v values and high thermal loads. This makes them the ideal choice for use with aggressive media. What’s more, friction bearings (plain bearings) can be used with confidence in applications involving contact with food or pharmaceutical products.

Properties

• Excellent chemical resistance
• Large temperature range of –100°C to +250°C
• Suitable for high circumferential speeds under dry running conditions
• Suitable for high p•v values under dry running conditions
• FDA-compliant materials for life science applications  

Application Examples

• Elringplast friction bearings: very good chemical resistance and wear characteristics in industrial washing machines
• MoldflonTM friction bearings: very high loads with damping properties for use in clutches
• MoldflonTM friction bearings: approvals for use with food and temperature resistance for use in conveyor systems in the food industry
• M-Liner dry friction bearings: low friction and thin layers for use in actuator pins in electromagnets
