NK series are basic needle roller bearings assembled with outer ring manufactured using heat treated high carbon chromium bearing, needle roller and carbon steel cage.

NK series has a low section height to save application space. If grinded shaft can not be used, you can attach inner ring as required for usage.

You can install oil hole and groove for filling grease on outer ring of NK (14/16 ~ 55/35) produced by our company to conveniently fill grease.

NK bearings can be used in various environments such as medium load and high-speed rotation.
