Compact radial support for tight spaces

Practical benefits

High radial load capacity: You accommodate heavy radial loads within extremely compact machine housings thanks to dense roller arrangements.
Space-saving ringless design: Mounting the NK 28/20 needle roller bearing directly onto a hardened shaft saves significant cross-sectional space.
Durable steel cage construction: You benefit from precise roller guidance and smooth continuous operation with the robust sheet steel cage.

In a nutshell

The right choise for

With the Skf nk 28/20 needle roller bearing, you achieve high radial load carrying capacity within minimal installation space. Designed without an inner ring, this single-row bearing mounts directly onto a 28 mm hardened and ground shaft raceway, saving valuable cross-sectional space and weight in compact gearboxes, hydraulic pumps, and industrial machinery. The durable sheet steel cage ensures precise roller guidance to reduce friction and shaft wear. In addition, the outer ring features an annular groove and lubrication hole to make routine relubrication quick and straightforward.
