PTFE bearings are specialized sliding bearings crafted mainly from polytetrafluoroethylene (PTFE), a polymer with remarkable properties. They boast excellent wear and friction resistance, reducing energy loss and extending component life. Their superior corrosion resistance allows them to endure aggressive chemicals, acids, and alkalis, while their wide temperature tolerance suits both cryogenic and high-heat settings. Various types exist: self-lubricating ones need no external lubrication, chemically inert ones resist harsh substances, and reinforced ones with fillers handle heavy loads without losing PTFE’s benefits.

These bearings are widely used in automotive suspension and engine parts, consumer electronics for quiet operation, and the food industry for hygiene and cleaning agent resistance. They offer long service life, low maintenance, and high reliability, cutting operational costs and downtime. Many manufacturers provide customized PTFE bearings to meet specific needs for unique environments, loads, or system integration.
