*Stock
units are calibrated with equal cw and ccw slip torques
corresponding to the tabulated Upper Limit Torques.
Other torques are readily availabe from full, down to
1/8 of the upper limit torque for each model. Torque
values are independent of each other for cw and ccw
rotation, and may be specified the same or different
for the two directions.

GM-B
Series slip clutches are designed for long life under continuous
slip conditions. The useful life of these elements is a
function of transmitted torque and slip speed. Refer to
page A-2 for the method of estimating life for a particular
application. The service life factors are based on continuous
duty testing on mildly hard wear surfaces. Service life
may be extended by a factor of approximately 4X by specifying
Nitride surface treatment in "wear-critical" applications.
**All
clutches in this series have a pilot diameter "K", and three
tapped holes "N" for mounting a gear, sprocket or pulley
on the input hub. Screw penetration into the clutch housing
must not exceed the depth specified in column "N". |
Input
gears, sprockets or pulleys are available as optional items
or can be "designed-in" as integral assemblies. Pages B-4
and B-5 list standard "PB" and "CX" Series clutches with
integral 1/5" gearbelt pulleys.Refer to section "K" for
other special units.
