Function and purpose:
1. Internal: Locks the gear oil of the wheel hub reducer to prevent the leakage of the gear oil outward;
2. External: Prevents mud, water, sand, and dust from entering the hub bearing and the wheel hub reducer;
3. If this oil seal leaks: The gear oil will splash onto the brake drum and brake pads, directly causing brake failure, which is a high-risk component.
Material:
1. The rubber is a nitrile rubber compound resistant to oil. The rubber has uniform hardness, a complete double lip structure, and the metal frame has no burrs.
2. The feel is heavy, and the weight is significantly greater than that of ordinary spares.
Installation instructions:
1. Apply a small amount of gear oil to the lip of the oil seal, and do not use it dry.
2. It must be pressed in evenly using a dedicated press sleeve, and it is strictly prohibited to strike the rubber surface of the oil seal directly.
3. The flat end of the oil seal faces outward, and the spring lip faces the gear oil cavity on the wheel edge. Installing it in the reverse direction will cause oil leakage.
The hub seals are located inside the vehicle's wheels. Their main function is to seal the axle bearings and prevent the leakage of lubricating oil and the entry of contaminants. This dual function makes them an integral part of the wheel assembly.
One of the main purposes of the hub seals is to maintain the lubrication of the axle bearings. These bearings that enable the wheels to rotate smoothly require continuous lubrication to prevent wear. By sealing the area around the axle bearings, the hub seals ensure that the lubricating oil remains where it is needed.
Another important use of the hub seals is to protect the axle bearings from contamination. Dust, dirt, and water, if they enter, may cause severe damage to the bearings.
