Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, NU design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
High radial load carrying capacity
Low friction
Long service life
Accommodate axial displacement in both directions
Separable design
Types of Cylindrical Roller Bearings
NU, N, NNU, NN: Suitable as free-end bearings.
NJ, NF: Can sustain limited axial loads in one direction.
NH, NUP: Suitable as fixed-end bearings. NH types are comprised of a NJ-type CRB with a HJ-type L-shaped thrust collar.
