130*160*14.5/16 For Wheel Hub Cassette Type Seal

The function of the oil seal is to isolate the parts that need lubrication from the output parts in the transmission parts, so as not to let the lubricating oil leak. It is usually used in the transmission parts.
The skeleton acts as a reinforcing steel bar in concrete members and keeps the shape and tension of the oil seal.
The NBR skeleton oil seal is made of high-quality nitrile rubber and steel plate, with stable quality and long service life.
It is widely used in automobile, motorcycle crankshaft, camshaft, differential, shock absorber, engine, axle, front and rear wheels, and other parts.

Overview of cassette oil seal
cassette oil seal, also known as cassette sealing ring, is a device used for axial sealing, often used in automobiles, machinery and other equipment. The cassette oil seal is mainly sealed by the friction between the shaft and the inner ring. It can not only prevent oil leakage, but also prevent dust, moisture and other impurities from entering the inside of the equipment.

Installation precautions
1. Before installing the cassette oil seal, clean the surface of the shaft and inner ring to avoid contamination or damage to the oil seal.
2. Pay attention to the strength when installing the cassette oil seal, do not squeeze or damage the oil seal.
3. After installing the cassette oil seal, the installation should be checked to ensure that the installation is correct.
4. If the cassette oil seal has been aged or damaged, it should be replaced in time

Wheel Hub Oil Seal
The main function of the hub oil seal is to seal the lubricating oil inside the hub. Its main function has two points: first, through the main seal lip of the oil seal, it can effectively prevent the leakage of lubricating oil and ensure that the bearing maintains a good lubrication state; Secondly, it can also avoid the pollution of the lubricant to the brake pads and brake drums, thereby reducing the decline in brake performance or possible failure.

Benefits:One of the key benefits of wheel hub seals is their ability to protect the wheel bearing from damage caused by moisture and other contaminants. When water or dirt enters the wheel bearing, it can lead to corrosion, friction, and ultimately, failure of the bearing. By installing a quality wheel hub seal, you can help to prevent these issues and ensure that your vehicle's wheel hub assembly remains in optimal condition.
In addition to protecting the wheel bearing, wheel hub seals also help to maintain proper lubrication within the wheel hub assembly. The seal helps to keep the lubricant contained within the wheel bearing, preventing it from leaking out or becoming contaminated. 
This is essential for ensuring that the wheel hub assembly operatesl smoothly and efficiently, minimizing friction and wear on the moving parts.
Another important function of wheel hub seals is to provide a barrier against external elements such as dust, sand, and road debris. These contaminants can cause damage to the wheel hub and other components of the vehicle, leading to reduced performance and safety. By keeping these elements out, wheel hub seals help to preserve the integrity of the wheel hub assembly and ensure that your vehicle remains in top condition.

Truck Oil Seal

Truck oil seals are made up of a rubber seal and a metal housing. The rubber seal is normally made of a synthetic rubber such as nitrile butadiene rubber or polychloroprene which is a blend of these two rubbers. This rubber is designed to withstand high temperatures, pressure and oil viscosity. The metal housing is generally made of stainless steel or aluminum and is designed to provide the oil seal with adequate support and protection against the environment. The joint between the rubber seal and metal part can be filled with a sealing compound such as silicone or polyurethane. The combination of all these materials provides the oil seal with a good seal and long service life.
