PTFE oil seal

PTFE oil seal, also known as PTFE oil seal or PTFE oil seal, is made of the same material as the PTFE sealing ring you asked earlier, and belongs to stable performance rotary oil seals.

feature

Low friction coefficient, good self lubrication, no wear on the shaft, suitable for high-speed rotation

Resistant to high and low temperatures, can be used for a long time up to 73K~533K (-200 ℃~260 ℃)

Resistant to almost all chemical media, oils, solvents, acids and bases, non corrosive and non aging

Wear resistant (based on actual reports), pressure resistant, and have a much longer lifespan than ordinary rubber oil seals

Clean without precipitation, meeting the requirements of food, medicine, and semiconductor

structural form

Generally, it is a combination structure of PTFE lip sleeve and metal/rubber support

Single lips, double lips, and spring-loaded fasteners are all common

Commonly used for high-pressure, high-speed, and precision suitable rotary seals

Applicable scenarios

Machine tool spindle, high-speed motor, air compressor

Hydraulic pump, servo motor, gearbox heavy-duty parts

Engine front and rear oil seals, differential oil seals

Clean sealing of chemical, food, and pharmaceutical equipment
