High radial load capacity with Skf

Practical benefits

Extremely compact design: By using the shaft directly as a raceway without an inner ring, you save valuable radial space.
High radial stiffness: The machined outer ring and steel cage give you dependable rigidity and high dynamic load ratings.
Simple and fast relubrication: You maintain smooth operation easily thanks to the lubrication groove and holes in the outer ring.

In a nutshell

The right choise for

With the Skf nk 22/20 needle roller bearing, you achieve an extremely compact bearing arrangement capable of handling high radial loads in tight spaces. Because this single-row bearing is designed without an inner ring, a hardened and ground shaft serves directly as the raceway. This saves valuable radial installation space and weight in gearboxes, reduction units, and hydraulic pumps. The solid outer ring with integral flanges and a sheet steel cage ensures high rigidity and smooth operation at high rotational speeds. Thanks to the lubrication groove and lubrication holes in the outer ring, regular relubrication and maintenance are straightforward.
