Compact support for high radial loads

Practical benefits

Space-saving shaft integration: By running directly on a hardened shaft without an inner ring, you achieve a minimal cross-sectional mounting height.
High radial load capacity: The Skf NK 25/20 machined needle roller design delivers outstanding rigidity to handle demanding radial forces with ease.
Easy relubrication and guidance: Integral flanges keep the rollers axially aligned while dedicated lubrication features allow for smooth routine maintenance.

In a nutshell

The right choise for

With the Skf nk 25/20 single row needle roller bearing, you achieve an extremely compact bearing arrangement for demanding radial loads in gearboxes, drive systems, and machine engineering. Engineered without an inner ring, this needle roller bearing runs directly on a 25 mm hardened and ground shaft, saving valuable installation space and weight. The machined outer ring with a 33 mm outside diameter and 20 mm width, combined with a strong sheet steel cage, ensures exceptional rigidity and high radial load carrying capacity. Integrated flanges keep the needle rollers precisely aligned axially, while the open design without seals allows for straightforward lubrication through your system.
