SKF NJ Design metric single row cylindrical roller bearing with polyamide cage and C4 clearance

SKF Single row cylindrical roller bearing, NJ design

SKF 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 one on the inner ring, NJ design bearings can accommodate axial displacement in one direction. 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
Locate the shaft axially in one direction
