Compact performance with Skf

Practical benefits

Minimal radial space required: Designing without an inner ring allows you to mount directly onto a hardened shaft for a low cross-sectional height.
High radial load capacity: The numerous needle rollers reliably support heavy radial loads while maintaining high assembly stiffness.
Durable sheet steel cage: The sturdy pressed steel cage guides rollers accurately to reduce friction during demanding mechanical operation.

In a nutshell

The right choise for

When you need high radial load capacity within tight installation spaces, the Skf nk 20/20 single row needle roller bearing delivers the right performance. Designed without an inner ring, it mounts directly onto a 20 mm hardened and ground shaft, saving valuable cross-sectional space in gearboxes, reducers, and pump mechanisms. Its needle rollers handle a dynamic load rating of 16.5 kN and a static load rating of 25.5 kN while ensuring rigid guidance. With a durable sheet steel cage that aligns the rollers accurately to reduce friction, this open bearing with 28 mm outside diameter and 20 mm width keeps your machinery running smoothly.

Product description

Single row needle roller bearings without an inner ring consist of an outer ring with a needle roller and cage assembly. They are an excellent choice for compact bearing arrangements in applications where hardened and ground raceways can be provided on the shaft. 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.

High radial load carrying capacity
High stiffness
Low cross-sectional height
Accommodate axial displacement in both directions
