What is a NOK Oil Seal?

xtnbk supply professional and honest service.

An NOK oil seal is indispensable for sealing machines against oil, lubricants, water, and gases. These oil seals also prevent dirt from outside sources such as dust, dirt, and sand particles. NOK oil seals have diverse applications across multiple industries, and their legacy spans a long history. The products we export worldwide deliver consistent quality.

What is the construction of a NOK Oil Seal?

NOK oil seals are made from synthetic rubber which forms the sealing lip, while some oil seals include a metal spring. This spring provides added grip on the shaft, enabling effective sealing of moving parts.

When installed correctly in rotary applications, NOK oil seals draw in a small amount of air that prevents oil from leaking. In reciprocating applications, oil leakage occurs due to the disparity in oil film thickness during push and pull movements, necessitating an accurate sealing pressure profile for optimal oil film thickness.

How do I recognize a NOK oil seal?

It’s easy to identify a NOK oil seal as they typically display a "NOK" marking on the side, along with specific type and size indicators.
