  • 1 Stock units are calibrated with equal CW and CCW slip torques corresponding to the value of the Upper Limit Torques listed in the table above. Brakes can also be calibrated with slip torque values lower than the maximum values shown. When ordering, the CW and CCW slip torque values may be specified anywhere from the full torque value listed, to a lower value of approximately 1/8 of this maximum, and may be be specified the same or different for each of the two directions of rotation.
