PTFE oil seal

PTFE oil seal is an oil seal with a lip made of polytetrafluoroethylene (PTFE/Teflon), also commonly known as PTFE oil seal or PTFE oil seal. It belongs to the stable and wear-resistant (based on actual reports) type of oil seal.

feature

Wear resistant (based on actual reports), resistant to high and low temperatures, with a relatively low coefficient of friction, and non stick to the shaft

Resistant to almost all types of oils, chemical solvents, acid and alkali corrosion

High temperature resistance (based on actual reports) can reach 260 ℃~280 ℃, and low temperature stability can also be maintained

Non aging, long lifespan, suitable for high-speed, high-pressure, and clean working conditions

Generally, rubber or springs are used internally to provide clamping force

Common structures

PTFE lip+rubber inner bag+metal frame

Double lips, single lips, and spring-loaded clamping structures are available

Many of them are rotary oil seals, power steering oil seals, and high-pressure hydraulic oil seals

Applicable scenarios

High speed rotating shaft, machine tool spindle, air compressor

High temperature gearbox, engine front/rear oil seals

High pressure seals for hydraulic pumps, motors, servo mechanisms, etc

Clean and precipitation free working conditions for food, pharmaceutical, and chemical equipment
