Single row needle roller bearing with machined rings, with flanges and integral sealing
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
