oil seal

Oil seal is an oil sealing component, mainly used for sealing oil, preventing oil leakage, and blocking dust. It is often used for rotating shafts and rotating parts and is a common sealing component in machinery.

brief description

Core purpose: Keep lubricating oil inside the equipment to prevent oil leakage

Simultaneously blocking the entry of mud, dust, and impurities from the outside into the box

Mostly used in rotating parts such as motors, bearings, gearboxes, axles, engines, etc

Common types

Skeleton oil seal: with metal inner skeleton, good rigidity, not easy to deform, commonly used

Skeleton free oil seal: pure rubber structure, soft, mostly used for low-speed and simple working conditions

TC oil seal: Double lip structure with spring, inner lip seals oil, outer lip dustproof, most widely used

Fluorine rubber oil seal and nitrile oil seal: distinguish temperature resistance and oil resistance according to rubber material

Applicable scenarios

Automotive engine, crankshaft, half shaft, gearbox

Reducer, water pump, motor, machine tool spindle

Rotating parts such as construction machinery, hydraulic equipment, and air compressors
