- gaskets and rubber tubes.
In addition to selecting the right type of oil seal, it is essential to consider the operating conditions of the equipment. Factors such as temperature, pressure, and speed can impact the performance and longevity of the seal. Choosing a seal that is rated for the specific operating conditions will help ensure reliable sealing and extended service life.
- * Nitrile Known for its excellent oil resistance, nitrile rubber is widely used in applications that involve exposure to oils, fuels, and greases.

Several variables, including maximum temperatures, required lubricants, available space, and more, may influence your choice of bearing seal. Each factor can affect the type of bearing best for your application, the amount of material required, and other factors. Although the choice of seals is crucial to the effectiveness of your bearings, you don’t have to make that choice alone. Our experts at NBC bearings can collaborate with you to identify the bearings and bearing seals that provide the best, most affordable solution for your application, environment, and finished product.
The intake valve cover gasket is a vital component that ensures the proper sealing of the intake valve cover, preventing oil leaks and maintaining the integrity of the engine's intake system. This gasket is essential for maintaining the efficiency and reliability of the engine, contributing to optimal engine performance and longevity.
By preventing lubricants from escaping, they protect key components of machinery from being damaged by leaks of various fluids. Everything from car engines to assembly machines use these oil seals to remain free from any harmful interactions that can cause serious and expensive damage to any of their critical parts.
The edge of the metal is finely ground after seal manufacture in a centerless grinder to enable an interference fit in the oil seal housing. A slight chamfer on the outer diameter (OD) of the seal is desirable for easy assembly. The sealing lip is prepared by buffing, grinding or cutting away the rubber flash which occurs at the sealing edge. A fine sealing edge creates sufficient pressure on the shaft to minimise spring load, leading to lower friction whilst maintaining effective seal performance. The garter spring plays an important role in the efficiency of the oil seal. If its tension is too high, heat will be generated between the sealing lip and the shaft, and result in rapid wear of the lip. If too low, the spring will be ineffective and the sealing lip will be worn away leading to leakage of the fluid.
There are many different materials used to manufacture oil seals.

In conclusion, the piston oil seal is a critical component in an internal combustion engine. It plays a vital role in preventing oil leakage, reducing friction, and ensuring efficient engine operation. Regular inspection and maintenance of the piston oil seal are essential for maintaining the performance and longevity of the engine.
NNK is committed to the best raw materials, and uses advanced technology and equipment to solve oil seal problems for customers. Our products not only ensure the sealing effect, but also minimize the friction force. The service life is longer than the average service life of oil seals. less loss.
Due to having a higher density, Viton has the widest temperature range of -40°F to over 400°F (-40°C to over 240°C) making it a perfect choice for higher temperature applications. Viton® also has the largest range of chemical resistance, i.e., it is resistant to silicone oil and grease, mineral/vegetable oil and grease, aliphatic, aromatic, and chlorinated hydrocarbons, non-flammable hydraulic fuels as well methanol fuels, and more.
