Maximum radial capacity in compact spaces

Practical benefits

High radial load capacity: The compact needle design allows you to handle substantial radial forces in tight housings.
Direct non-hardened shaft mounting: With the Skf NKI 12/20 inner ring, you easily install the bearing on non-machined shafts.
Effortless relubrication access: The outer ring lubrication hole lets you perform maintenance and apply grease quickly during operation.

In a nutshell

The right choise for

With the Skf nki 12/20 needle roller bearing, you easily handle high radial loads within minimal radial space. Thanks to the included inner ring, you can install this single row bearing directly on non-hardened shafts without requiring prior shaft hardening. The solid outer ring features a lubrication groove and lubrication hole for quick relubrication during regular maintenance. Its separable design allows you to mount the inner and outer ring assemblies independently for a smooth, flexible installation.

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.
