PTFE oil seal

Polytetrafluoroethylene oil seals, also known as PTFE oil seals/PTFE oil seals/PTFE oil seals, belong to stable performance rotary shaft seals. They are far superior to ordinary rubber oil seals in terms of wear resistance (based on actual reports), temperature resistance, and corrosion resistance (based on actual reports).

Main Features

The material is polytetrafluoroethylene (PTFE), which has good self-lubricating properties, low friction coefficient, and does not wear the shaft neck

Wide range of high and low temperature resistance, can be used for a long time from -200 ℃ to+260 ℃

Strong chemical stability, resistant to various types of oil, hydraulic oil, solvents, acid and alkali corrosion, almost no aging

Good pressure resistance and high-speed performance, suitable for high-speed and precision equipment

Clean toxin detection, no precipitation, can be used for food, medicine, semiconductor equipment

Common structures

Generally, it is a combination of metal skeleton, rubber support, and PTFE sealing lip

Many with spring clamping, double lip structure, oil sealing and dust-proof integrated

There are also springless oil seals made of pure PTFE for special working conditions

Applicable scenario a

Machine tool spindle, high-speed motor, air compressor, turbine machinery

Heavy duty and high-temperature rotating parts such as engine, gearbox, differential, etc

Hydraulic pump, servo motor, chemical pump shaft seal

Sealing of food machinery, pharmaceutical equipment, and clean production lines
