High radial load capacity for compact assemblies

Practical benefits

High radial load rating: Thanks to the large roller count, you carry heavy radial loads while maintaining an exceptionally low cross-sectional height.
Works on unhardened shafts: The included machined inner ring allows you to mount the Skf NKI 25/30 needle roller bearing without preparing a hardened shaft.
Easy and reliable relubrication: An annular groove with lubrication holes in the outer ring lets you apply grease directly for efficient routine maintenance.

In a nutshell

The right choise for

With the Skf nki 25/30 single-row needle roller bearing, you achieve high radial load capacity within compact assemblies where radial space is limited. Thanks to the included machined inner ring, you mount the bearing directly onto unhardened or unground shafts without special preparation. Machined solid rings with integral flanges keep the rolling elements precisely aligned and prevent axial displacement. Measuring 25X38X30 mm, this open bearing is designed for external lubrication. The outer ring features an annular lubrication groove and lubrication holes, making routine relubrication fast and efficient. This ensures dependable, smooth operation across gearboxes, drivetrains, and heavy-duty industrial machinery.

Product description

Single row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication.
