Description of custom-made one way ratchet bearing for resucer
This type star wheel one way ratchet wheel 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 of the one way ratchet 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 misalignment of inner and outer race of ± S/2.
