Oil Seal

What is an oil seal?

Oil seals, referred to as seals, are industrial products made of rubber and iron. They are either pure rubber or a combination of rubber and iron. They are mainly used in mechanical equipment parts to seal dust and oil. to achieve protection and sealing.

What types of oil seals are there?

1.TC type Oil Seal

The most common type of oil seal is the TC type, also referred to as skeleton oil seal, which includes skeleton oil seal and double-lip spring oil seal. This is the most widely used oil seal. There are more than 2,000 commonly used models. Currently, there are 5,000+ models in use. The inner diameter Widely used from 10 to 1000, machinery, agricultural machinery, bearings, water pumps, cars, tractors, automobile oil seals are used everywhere, among which the most commonly used TC oil seal models are 60*80*10, 35*60*10, 20*30 *5 and other sizes, the main rubber materials used are nitrile materials, silicone materials, and fluorine rubber materials, so they are also called NBR TC oil seals and FKM TC oil seals. With the development, TG and TG4 oil seals have also appeared. They are improvements of TC. The models are of external thread structure, but their sizes and application scenarios are the same and they can be used instead of each other.

2.Automobile oil seal

Car oil seals are also called Car oil seals. There are many types of car oil seals. Car oil seals are mainly used in car engines, wheel hubs and crankshafts. There are many types of car oil seals, including TA oil seal, TB oil seal, HTCL oil seal, crankshaft oil seal, HTCL oil seal, and HTCR. Oil seals, TBY, TAY oil seals, TB5Y, SCA, hub oil seals and other types. Automotive oil seals are widely used in cars, light trucks, and heavy trucks. In addition, there is also a lot of demand for power steering oil seals in automobile oil seals. It plays a huge role in protecting the steering oil seal from oil leakage and dust intrusion. There are hundreds of models of steering oil seals. The main models are TA68*90*10, TB50* 70*9, HTCL78*110*8.5, TBY70*112*10/18, TB5Y100*120/124*15, SCJY26.5*40*8.5

3.Hydraulic oil seal

Hydraulic oil seals are mainly used in hydraulic pumps and motors. They are mainly used for sealing functions to prevent dust and oil leakage. Hydraulic oil seals mainly use polyurethane materials. The representative product of hydraulic oil seals is UN oil seals. The size of UN oil seals that are currently widely used There are more than 2,000 models, in addition to UHS/JA/IDI/etc. oil seals, SPGW and KDAS seals are also widely used.

4. High pressure oil seal

High-pressure oil seals are mainly used in high-pressure pumps, bearings, motors and other equipment, and need to withstand a certain pressure for sealing. There are two common types of high-pressure oil seals, TCN and TCV, which are similar to TC oil seals, but have a high-pressure iron shell leaking from the outside. TCN and TCV high-pressure oil seals also use nitrile and fluorine rubber as raw materials, but the materials are different from other types and are customized pressure-resistant rubber.

Application of oil seal

Oil seals are used everywhere, as long as there are mechanical equipment, oil seals are needed, such as cars, airplanes, ships, trains, machine tools, cranes, motorcycles, tractors, excavators, our common bearings, engines, hubs, pumps, etc. Oil seals are needed in equipment to protect components, seal dust and prevent oil leakage. Although oil seals cannot be seen, they play important functions in all walks of life.
