HTGL type automotive oil seal for engines and transmissions

HTGL type oil seal, belonging to rotary oil seal, is mainly used for oil sealing. The periphery of the sealing lip is equipped with an oil return line, which can return the fluid leaking outward from the sealing lip to the inside through the function of spiral pumping. Therefore, this oil seal is mainly used for engine crankshaft front oil seal, crankshaft rear oil seal, gearbox and so on.

The following is a detailed introduction of HTGL type oil seal:

1. Features of HTGL type oil seal
   • Rotary oil seal design: HTGL type oil seal is specially designed for rotary shafts, which can adapt to the sealing requirements brought by the rotary movement of the shaft. This type of oil seal is usually used in automobile engines, gearboxes and other rotating shaft components.
   • Sealing lip design: The sealing lip is the core part of HTGL type oil seal, which is usually made of elastic material (such as Viton, amino rubber, etc.). The design of the sealing lip ensures that the seal forms a tight seal on the rotating shaft and prevents lubricant leakage.
   • Skeleton structure: HTGL type oil seals may be constructed with a skeleton structure (e.g., metal skeleton) to provide additional support and strength. The presence of the skeleton enhances the pressure and wear resistance of the oil seal.
   • Oil return feature (optional): Some HTGL type oil seals may be designed with an oil return line or similar feature to direct oil leaking from the seal lip back inside. This design helps to minimize oil leakage and improve seal reliability.
2. Application Areas
   • Engine: In automobile engines, HTGL type oil seals are used to seal rotating parts of the engine, such as crankshaft front and rear seals, to prevent lubricant leakage and to protect internal engine components.
   • Transmission: In transmission, HTGL type oil seal is used to seal the lubricating oil inside the transmission, preventing the oil from leaking from the shaft seal and keeping the lubricating system of the transmission working normally.
   • Steering system: HTGL type oil seals can also be used in the steering system of automobile, sealing the rotating part of steering shaft, preventing the lubricant from leaking and external pollutants from entering the system.
   • Other automobile parts: It can also be used in other automobile parts, such as drive shafts, differentials, etc., to provide effective sealing and protection.
