High radial load capacity with Skf NKI 28/30

Practical benefits

High radial load capacity: Thanks to the large number of rollers, you easily support heavy radial forces in compact installations.
Low cross-sectional height: With its compact profile, you save critical machine space without sacrificing structural rigidity or performance.
Fast and convenient relubrication: Using the annular groove and lubrication holes, you deliver fresh lubricant directly into the bearing.

In a nutshell

The right choise for

With the Skf nki 28/30 single row needle roller bearing, you reliably support heavy radial loads in compact machine assemblies. Its low cross-sectional height and high rigidity help you make the most of limited installation space in industrial gearboxes, transmissions, and conveyor systems. The included inner ring eliminates the need to harden and grind the shaft surface, allowing fast and secure mounting onto standard shafts. Featuring an annular groove and lubrication holes in the solid outer ring, this open bearing lets you deliver fresh lubricant quickly and directly to keep your machinery running smoothly under demanding conditions.

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.
