Pin Key
The pin keys are a cylindrical pin placed in cylindrical groove in the shaft
and hub. Lower stress concentration factors results from this design as
compared with parallel or tapered keys. A close fit between the pin and
the groove is required to ensure that the pin does not move and that the
bearing is uniform along the length of the pin.
