Reliable load capacity with Skf

Practical benefits

High radial load rating: Due to the large number of needle rollers, you handle heavy radial loads within a very compact design.
Dual integrated contact seals: The contact rubber seals keep dirt and contaminants out while ensuring effective lubricant retention for extended service life.
Convenient relubrication features: You easily regrease the bearing directly through dedicated lubrication holes and an annular groove on the solid rings.

In a nutshell

The right choise for

With the Skf na 4902.2RS needle roller bearing, you achieve reliable load support within a very compact radial space. Thanks to the included inner ring, you easily mount this single-row bearing directly onto non-hardened shafts in gearboxes, pumps, and industrial drive systems. Integral contact rubber seals on both sides (.2RS) keep dirt and moisture out while effectively retaining lubricant inside for long service life. For smooth maintenance, the machined rings feature lubrication holes and an annular groove for straightforward regreasing. Measuring 15X28X14 mm, it delivers high radial load carrying capacity for demanding mechanical builds and maintenance jobs.

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
