Applications of PTFE bearings
PTFE bearings are typically used in applications requiring low friction, chemical inertness and clean operation, such as food processing machinery, chemical handling equipment, medical devices and precision instruments. The Teflon-based material offers low sliding resistance and resistance to many aggressive media, making it appropriate where lubrication is limited or contamination must be minimised; its low adhesion and favourable friction characteristics can improve performance in light-to-moderate load, slow-speed assemblies. These bearings may be less suitable for sustained heavy or shock loads, high-abrasion environments or continuous elevated-temperature use, since PTFE can creep and exhibit accelerated wear under those conditions. Selection of ptfe components depends on the expected load and thermal profile.
