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.

When deciding on the best type of seal for a particular application, it is best to consider all aspects of the environment and its purpose. If the application requires a spring- loaded seal, that does not eliminate either the rotary shaft seal or the mechanical seal. If the equipment is operating in extreme temperatures, including situations where the rapid movement of the equipment creates extreme heat, a mechanical seal will hold up better than an oil seal.
