What is an oil seal?

Oil Seal, Also Known As Oil Seal, Is A Mechanical Component Specially Used For Sealing Lubricating Oil. It Effectively Separates The Part Of The Transmission System That Needs Lubrication From The Part That Outputs Force, Preventing The Leakage Of Lubricating Oil. There Are Various Forms Of Oil Seals, Among Which Tc Oil Seals Are Particularly Common. This Oil Seal Is Completely Wrapped By Rubber And Has A Double Lip Design With A Self-Tightening Spring, Which Provides A Reliable Sealing Effect For The Transmission System.

When Manufacturing Oil Seals, A Variety Of Materials Are Widely Used, Including Nitrile Rubber, Fluororubber, Silicone Rubber, Acrylate Rubber, Polyurethane And Polytetrafluoroethylene. These Materials Have Their Own Characteristics. For Example, Nitrile Rubber Has Good Heat Resistance And Wear Resistance And Can Work Stably In A Variety Of Lubricating Oils; While Polyacrylate Rubber Stands Out For Its Excellent Oil Resistance, Heat Resistance And Wear Resistance. Fluororubber Is Suitable For Almost All Lubricating Oils Due To Its Aging Resistance, Heat Resistance And Oil Resistance; Silicone Rubber Can Maintain Its Performance Unchanged For A Long Time At Extreme Temperatures. Polytetrafluoroethylene Occupies A Place In Oil Seal Materials With Its Chemical Stability, Thermal Stability And Self-Lubricity.

When Selecting Oil Seal Materials, Factors Such As The Working Medium, The Working Temperature Range, And The Ability Of The Lip To Follow The Rotating Shaft Need To Be Considered Comprehensively. For Example, Nitrile Rubber And Fluororubber Are Two Commonly Used Oil Seal Materials. The Former Has Low Cost But Limited Performance, While The Latter Has Superior Performance But High Cost. Polytetrafluoroethylene Oil Seals Represent A New Development Direction Of Oil Seal Technology And Have Attracted Widespread Attention For Their High-Tech Content And Excellent Performance.
