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
convenient bolt circles 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.
Adjustment
Loosen the two torque adjust set screws and rotate large knurled adjustment ring to the desired
relative setting. Re-tighten set screws to insure that the adjustment won’t slip. Both hysteresis
and eddy current units are adjustable.

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.
Heat Dissipation
For all continuous slip applications over 1500 rpm (size 2) and 450 rpm (size 4 and 5) heat
generation and dissipation capacity should be considered.
Calculate as follows: W = .0118T x rpm
Where W = watts
T = torque (lb-in)
rpm = slip speed
For continuous duty applications, maximum
watts should not exceed 10 (size 2), 22 (size 4)
and 72 (size 5).
Overhung Load Capacity
Distance from face of Perma-Tork unit is 1 inch.
