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
• Separable design
