it consists of a machined outer ring with ribs (rolling bearing steel), a needle roller and cage assembly as well as an inner ring
it has an excellent radial load capacity
non-sealed needle roller bearings have a temperature resistance ranging from -20°C up to +120°C
it is usable if the shaft cannot be hardened and ground
there is the possibility of using a broader inner ring instead of the standard inner ring in case of greater axial displacements
