Have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited. The outer rings of this kind of
Needle bearings and bearings cases are interference fitted without axial fixed settings. The effcient capacity can be maintained even if in the condition
Of high speed and huge loading capacity.
