Type NSS is a roller type freewheel non bearing supported.Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation.Nominal outside dimensions are the same as series 62.. ball bearings.
A typical arrangement is to install this type alongside a series 62 bearing within the same location tolerances.
The inner race is keyed to the shaft (except 6 mm bore). The outer race has a positive r6 tolerance to give a press fit in a H7 housing. The outer housing must be strong enough to not expand after assembly. This design can accept an axial mis-alignment of inner and outer race of ± S/2.
