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.

Stop Collar Adjustment
Each CB Series unit has an incrementally
adjustable collar, allowing for changes to the
output orientation.
To adjust the stop collar output orientation:
1. Remove the retaining ring from its groove and
slide it forward on the sleeve.
2. Hold the actuator clear while sliding the cam off
the sleeve. Rotate the cam to the desired stop
position, and slide it back onto the sleeve. (The
brake should be fully wrapped down to ensure
setting the proper stop point).
Note: Simply rotating the input hub until the
actuator hits the cam will not fully wrap down
the brake spring.
Wrapping the brake spring down completely
can be accomplished by rotating the output
shaft in driving direction until it cannot travel
any further.
