¹ Stock units are calibrated with equal cw and ccw slip torques corresponding to the tabulated Upper Limit Torque listed in the table above. Clutches can also be calibrated with slip torque values lower then 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 specified the same or different for each of the two directions of rotation. ² 1/5 pitch (3/8" pitch available)
