Polyimide yellow double lip PTFE dry grinding stainless steel oil seal dust resistant air high-speed rotating shaft oil seal (1pcs)

-Name: Stainless Steel Oil Seal-Material:Sealing lip: Polyimide (PI) filled/reinforced PTFE composite materialSkeleton: Stainless steelStructure: Double lips, with dust on both lips and a secondary lip design-Dimensions: Inner diameter * Outer diameter * Thickness (unit: mm)-Color: Lips Yellow LipsPerformance:Applicable temperature: -60 ℃~270 ℃ (depending on specific formula and operating conditions)Linear speed: Low speed conditions can cover conventional industrial speeds, and high-speed models are compatible with high-speed rotating shaftsDry friction/lean lubrication: PTFE self-lubricating properties support short-term dry grinding and low oil conditionsMedium resistance: dry abrasion resistance, wear resistance, high temperature resistance, corrosion resistance, high pressure resistanceFriction coefficient: PTFE substrate has a low friction coefficient and minimal axial wearProduct features:PI+PTFE composite: While retaining the low friction and chemical resistance advantages of PTFE, it enhances wear resistance and creep resistance, making it suitable for continuous rotating conditions.Stainless steel skeleton: It has good structural rigidity, corrosion resistance, and better dimensional stability than ordinary carbon steel skeleton.Dust resistant design: The secondary lip/dust-proof lip structure can block external dust and mud from entering the sealed chamber, suitable for dusty, outdoor or agricultural conditions.Dry grinding/lean oil adaptation: PTFE self-lubricating, can maintain sealing even during short-term dry friction or insufficient lubricating oil, reducing the risk of abnormal wear.High speed rotation adaptation: low friction heat generation, low rotational resistance, suitable for sealing requirements of high-speed rotating shafts.Advantages:① PI enhanced PTFE combines wear resistance and self-lubricating properties, with a longer lifespan than conventional rubber oil seals under similar harsh working conditions.② Stainless steel frame+dust resistant secondary lip, suitable for high temperature, dusty, and humid industrial and agricultural environments in Southeast Asia.③ It can still work under dry grinding/lean oil conditions, reducing the early failure caused by poor lubrication.④ Low friction and minimal wear on the shaft help protect the shaft surface and reduce downtime maintenance.Application fields:Automobile/commercial vehicle: crankshaft, wheel hub, transmission shaft rotating sealAgricultural machinery: rotary tillers, harvesters, tractors and other dusty working conditionsIndustrial pump valves: water pumps, oil pumps, vacuum pumps, chemical pumpsReducer/gearbox/bearing seatBlender, blower, compressorRotating shaft parts of construction machinery and hardware machinery
