An NOK oil seal is a indispensable for sealing machines against oil, lubricants, water and gases. The oil seals also stop dirt from the outside, such as dust, dirt and sand particles. The oil seals are used in various industries. The history of NOK oil seals is very long. The products we export worldwide deliver consistent quality.
NOK oil seals are produced from synthetic rubber, which forms the sealing lip. An oil seal may also have a metal "spring". This spring ensures that the oil seal has extra grip on the shaft, making it possible to seal moving parts.
NOK oil seals intended for rotary applications when properly installed suck in a little air which prevents oil from escaping and leaking out. NOK oil seals intended for reciprocating applications, the difference in oil film thickness between the push and pull movements constitutes the oil leakage. For example, the contact pressure profile of the oil seal is determined to achieve optimum oil film thicknesses.
An oil seal from NOK is easy to recognize. In general, the oil seals have a "NOK" marking on the side of the oil seals. Most oil seals also have an oil seal type and size marking on the side.
