axle gear box oil seal which is HSGL type skeleton

Therefore this oil seal is mainly used for engine crankshaft front oil seal, crankshaft rear oil seal, gearbox and so on. The key features and functions of HSGL type oil seals are described in detail below:

1. Rotary Oil Seal: HSGL type oil seal is specially designed to be used in rotary shaft system, so it can effectively deal with various sealing problems caused by rotation.
2. Sealing lip and return line: The sealing lip is uniquely designed with a return line around the periphery, usually in the shape of a helix, which effectively directs the fluid leaking from the sealing lip back to the inside of the seal. The spiral pumping action of the return line makes the leaked fluid be redirected into the system, thus reducing the leakage.
3. Sealing effect: Through the cooperation of the return line and sealing lip, HSGL type oil seal provides good sealing effect, which can effectively prevent oil leakage and stop the entry of external contaminants.
4. Application field:
   • Engine crankshaft front oil seals and rear oil seals: In the engine, HSGL type oil seals are commonly used in the front and rear ends of the crankshaft to ensure that the lubricating oil inside the engine will not leak.
   • Transmission Oil Seal: In the transmission, HSGL type oil seal is used to seal the lubricant inside the transmission, prevent the oil from leaking and keep the inside of the transmission clean.
   • Other rotating equipments: In addition to the above applications, HSGL type oil seals can also be used in other mechanical equipments that need to seal rotating shafts.
