NSK Self-Aligning Ball Bearings

With cylindrical rollers which are thin and long in relation to their diameter
They are referred to as needle rollers, in spite of their low cross section the bearings have a high load carrying capacity and are thus extremely suitable for bearing arrangements where radial space is limited
Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness
Suitable for bearing arrangements where radial space is limited
