3 Selection Instructions START WITH ONE OF FOUR BASI UNITS... Shaft Input Shaft Output -face Input Shaft Output AND ADD MOUNTING AESSORY KITS... Horizontal Base Kit Shaft Input Hollow Bore Output -face Input Hollow Bore Output Torque Arm Kit The ratings for gear drives in this manual are based on a service factor of 1.00, for uniform load and uniform power source, up to 10 hours of operation per day. For other operating conditions, the application horsepower or torque must be multiplied by the appropriate service factor, to determine the equivalent gear drive power rating. A gear drive should be selected with a rated capacity equal to or greater than the equivalent load. Table 1 designates recommended service factors for various conditions of load, power source, and duration of service. AGMA Service Factors for Worm and Helical Worm Gearmotors and Reducers are listed in Section A. Refer to page A-2 for further information and cautions on the selection of proper service factors. Input Rotation to Hub ity Spartan Worm Gear Reducers can be either clockwise or counter-clockwise. onsult factory for operation at input speeds above 1750 rpm. Maximum momentary or starting torque is limited to 300% of rated capacity.
