Shantui bulldozer spare parts oil seal 07013-10120

The oil seal in a bulldozer such as the Shantui SD22 serves a critical role in preventing leakage of oil or other fluids from various components of the machine. Oil seals are used in multiple locations throughout the bulldozer's engine, transmission, and hydraulic systems to maintain proper lubrication and prevent contamination. Here's an overview of the oil seal in the context of the Shantui SD22 bulldozer:

Function: The oil seal, also known as a shaft seal or radial shaft seal, is designed to seal the rotating shafts of components such as the engine crankshaft, transmission output shaft, hydraulic pump shaft, and other rotating elements. It prevents oil or hydraulic fluid from leaking out of the system while also preventing contaminants such as dirt, dust, and water from entering.

Material and Construction: Oil seals are typically made of rubber or elastomeric materials such as nitrile rubber (NBR), fluoroelastomer (Viton), or silicone, depending on the application requirements and the type of fluid being sealed. They consist of a flexible lip that makes contact with the rotating shaft, along with a rigid outer casing that is pressed into a housing or bore to secure the seal in place.

Installation: Oil seals are installed in specific locations where rotating shafts penetrate the housing or casing of a component. The seal is pressed into the housing or bore using a seal installation tool or press to ensure a tight fit and proper alignment with the shaft. Care must be taken during installation to avoid damaging the seal lip or the sealing surface of the shaft.
