Performance Characteristic of one way clutch ratchet
Structure: 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.
Installation: 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).
Tolerance: 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.
