Heavy load support by Skf

Practical benefits

High radial load capacity: Compact cylindrical rollers allow you to carry heavy radial loads within extremely confined spaces.
Integrated double contact seals: Dual rubber seals prevent contamination from entering while keeping essential lubricating grease securely inside.
Straightforward inner ring mounting: Featuring a machined inner ring, you achieve fast and stable installation directly onto machine shafts.

In a nutshell

The right choise for

With the Skf na 4908.2RS single row needle roller bearing, you reliably carry heavy radial loads within restricted spaces.

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. The inner ring contains an additional lubrication hole.

High radial load carrying capacity
High stiffness and low cross-sectional height
Accommodate axial displacement in both directions
Separable design
Integral sealing prolongs bearing service life
