Handling
Handle and install with care. This is a precision-assembled unit with close internal clearances.
Magnetic materials used are brittle by nature. Avoid subjecting to shock loads. DO NOT DROP.
Installation
Perma-Tork hollow shaft units are easily adaptable for use as either a clutch or brake. As a
clutch, either the hollow shaft or the housing can be the input. The unit mounts on a shaft, and a
convenient bolt circle and a pilot diameter provide ease of attachment to a gear, pulley, etc. A
stub shaft adapter can be used where a solid shaft interface is required.
Brake Units
HB6-1
1. Brake units must be securely mounted to a
mounting bracket or plate, using three
¼-20 screws and lockwashers (see “A” in
Figure 1and Figure 4).
Locking bolts and spanner wrench holes
must be readily accessible for adjustment.
(See Figure 4.)
2. Mount sheave, pulley, or sprocket to output
shaft as shown in Figure 1.

Clutch Units
HC6-58 and HC6-34
Clutch units are designed to fit NEMA 56C motors with keyed 5/8" or 3/4" output shafts.
1. Drill two 0.18 inch diameter clearance
holes in sheave or pulley 90º apart for
access to set screws in clutch shaft.
2. Counterbore sheave or pulley to a
diameter of 2.442/2.445 inches to permit
piloting on outer diameter of clutch
bearing.
3. Secure sheave or pulley to clutch using
three 1/4-20 socket head cap screws and
lockwashers.
4. Mount and firmly secure clutch on motor
or prime mover output shaft as shown in
Figure 2.
5. Align per timing-belt or drive-belt
manufacturer’s specifications.

Clutch Coupling
HC6-58 and HC6-34
Mounting requirements: This will require an adapter (not supplied) and a coupling (not supplied).
1. Mount clutch to motor or prime-mover
output shaft.
2. Make up and secure output shaft adapter
to clutch using 1/4-20 socket head cap
screws.
3. Couple input shaft adapter to load, using a
shaft coupling (see Figure 3).
4. Follow coupling manufacturers mounting
and alignment instruction, to minimize
misalignment and maximize Perma-Tork
life.

Adjusting Torque
Generally, this should be done while the unit is firmly and properly mounted in place. The
exception to this is when the adjustment must be done prior to mounting due to space
limitations. This can be accomplished by restraining the housing and adjusting the end cap with a
spanner wrench while rotating either the output shaft (brake) or input member (clutch).
This is a magnetically strong unit. Always take extreme caution while adjusting. It is
recommended that one person adjust unit with a spanner wrench, while a second
person moves prime-mover output shaft.
Torque Adjustment Procedure
These units are designed to use a standard 4" spanner wrench with 3/8" pins.
1. Make sure system is at a complete stop.
2. Loosen by one turn the four socket head cap screws “B” located on curved slots (see Figure 4).
−On BRAKE units, use spanner wrench to carefully hold Perma-tork magnets while making
adjustment.
−On CLUTCH units, the Perma-Tork housing must first be securely RESTRAINED in order to
make adjustments. Use spanner wrench to carefully make adjustment.
3. Starting slowly, rotate prime mover or output shaft while making torque adjustment to
eliminate possible cogging. (See Cogging section on page 4.)
4. After adjusting unit, tighten adjustment screws and remove spanner wrench.

Cogging
With hysteresis units there can be a slight “memory” effect on the hysteresis disc when changing
from a high to a low torque setting. This can result in “magnet lobes” or detents, causing minor
cogging. It is correctable by rotating the output shaft slowly (25 to 250 rpm) while moving the
adjustment from maximum to minimum.
Overhung Load Capacity
40 lbs within 2 inches from clutch face of Perma-Tork unit.
Maintenance
Properly installed, these units are designed to be maintenance free.
