Cylindrical Roller Bearings

Single-row cylindrical bearings are available in four following types: N, NJ, NU, NUP.

 1) N Type: The N-type cylindrical bearing consists of two integral ribs on the inner ring that retain the rollers and cage. No thrust capacity.

 2) NJ Type: The NJ-type bearing supports heavy radial loads and has the ability to carry light, unidirectional thrust loads that are up to 10 percent of the radial load. Features two integral ribs on the outer ring and a single rib on the inner ring.

 3) NU Type: The NU Type cylindrical bearing is the most popular in line-up, with the separable inner ring and the cage and roller complement mounted to the outer ring. No thrust capacity.

4) NUP Type: The NUP-Type also able to carry incidental thrust loads in both directions, and may be used with a type RN or RU to accommodate axial expansion and contraction. Two integral.
