OPTIONS: SERIES PB & PC CLAMPS SPEED REDUCER FITTINGS OPTION (continued) When Series PB or PC Clamps are used with standard ASA or ASB Arms, AB1 Antibacklash, WC1 Weld Covers and TA Spindles. Speed controls are NOT required. These graphs assume the following: The clamp is mounted vertically. Loads are attached to ASB Arms or identical customer-supplied aluminum arms. If longer arms or heavier loads are attached, clamps need to be protected from the higher Rotational Moment of Inertia (Jm) by slowing down their speed. PHD recommends nonadjustable speed reducing fittings for these...

OPTIONS: SERIES PB & PC CLAMPS SPEED REDUCER FITTINGS OPTION (continued) Jm for PHD supplied options are shown in Chart A. For customer supplied arms and attached loads, use the equations below to calculate the Rotational Moment of Inertial (Jm). Stay below the maximum allowable (Jm) and apply speed reducing fittings as required. CHART A - MAXIMUM ALLOWABLE MOMENT OF INERTIA MAX.
