for anti-rotation.
Figure 3 - Acceptable Mounting
The smaller CB units (sizes 2, 4 and 5) have
pilot holes in the output shaft, which guide
drilling through the machine shaft for attaching the
unit with a pin.
Vertical Mounting
When it is necessary to mount a unit vertically,
mount it so the input hub is oriented in the upward
position as illustrated in Figure 4.
Figure 4
In cases where easy access to the input is
desirable, the clutch/brake can be mounted
on a stub shaft. However, the unit must still
be fully supported, while overhung loads on
the input member must be avoided to
maintain the life of the radial bearing.
Figures 2 and 3 illustrate alternate mounting
configurations for achieving proper support. Inputs
are usually face-mounted to the input hub of the CB
unit as shown in Figure 1. This type of mounting is
facilitated by the drilled and tapped holes provided
in the free hub flange. The configuration shown in
Figure 2 is a possibility,
if the radial load on the
input hub of the CB is small compared to the
specified load.
Figure 2 - Acceptable Mounting
If the application contains a substantial radial
bearing load, arrange the pulley over the centerline
of the clutch free hub as illustrated
in Figure 3. Place one support bearing as close
to the pulley as possible, using a torque arm
