SERIES C EXPLANATION & USE OF RATINGS & SERVICE FACTORS Gear unit selection is made by comparing actual loads with catalogue ratings. Catalogue ratings are based on a standard set of loading conditions, whereas actual load conditions vary according to type of application. Service Factors are therefore used to calculate an equivalent load to compare with catalogue ratings. i.e. Equivalent Load = Actual Load x Service Factor Mechanical ratings and service factor Fm Mechanical ratings measure capacity in terms of life and/or strength, assuming 10 hr/day continuous running under uniform load...
