High radial capacity in tight spaces

Practical benefits

Strength with Skf NA 4910: You benefit from high radial load carrying capacity within a compact cross section, ideal for space-constrained mechanical assemblies.
Easy installation with inner ring: The included inner ring allows you to mount the bearing directly onto standard shafts without requiring specialized hardening.
Smooth guidance and stability: Integral flanges and a precision cage ensure you achieve smooth rotation and optimal roller guidance during demanding continuous operations.

In a nutshell

The right choise for

With the Skf na 4910 needle roller bearing, you easily handle heavy radial loads in space-constrained machinery. Featuring compact dimensions of 50X72X22 mm and machined rings, this bearing delivers exceptional load carrying capacity and rigidity. The included inner ring enables direct installation on standard shafts without requiring hardened or ground shaft raceways. Thanks to its separable, open design, you can mount the inner and outer rings independently with ease. Integral flanges and a sheet brass cage provide precise roller guidance, helping you minimize friction and premature wear in gearboxes, pumps, and industrial drive systems.

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.

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