The ratings for miter gearboxes in this catalogue are based on a service factor of 1.00. For other operating conditions, the application power or torque must be multiplied by the appropriate service factor, to determine the equivalent gear drive power rating. A bevel gearbox should be selected with a rated capacity equal to or greater than the equivalent rating. Below table designates recommended service factors for various conditions of load, power source, and duration of service.
Note: please use these data inside the brackets when "frequent starts and stops" refers to more than 10 starts per hour.
Note: time specified for intermittent and occasional service refers to total operating time per day.
