EMAIL: A-1. & Service Factor load Class Information Class of Service and Service factors The ratings for gear drives in this manual are based on Table 1 indicates the relationship between Service factors a Service Factor of , for uniform load and uniform and load classification numbers. power source, up to 10 hours of operation per day. For other operating conditions, the application horsepower The AGMA load classification numbers and Service or torque must be multiplied by the appropriate Service factors are based on a uniform power source.

2 If other Factor , to determine the equivalent gear drive power power sources are used, the Service factors must be rating. A gear drive should be selected with a rated converted using Table 2. Determine the required Service capacity equal to or greater than the equivalent rating. Factor with uniform power source. Locate that Service Factor in the first column and read straight across to A condensed Service Factor chart is located in the obtain required Service Factor with multi-cylinder or single selection information pages for each type of gear drive cylinder engines. or reducer. Service factors do not need to be used with thermal AGMA Service factors for Worm and Helical Worm ratings. Gearmotors and Reducers are listed on pages A-3 to A-4.
