Electric motors, generators, engines, compressors andother machines fitted with sleeve or straight roller bearings, usually require limited endfloat couplings. If in doubt, provide axial clearances and centering forces to one of ourApplication Engineers for a recommendation.For balanced opposed design, refer to our Application Engineers.If people are occasionally transported, refer to our Application Engineers for the selectionof the proper size coupling.For high peak load applications (such as Metal Rolling Mills) refer to our ApplicationEngineers.Service Factors for engine drives are those required for applications where good flywheelregulation prevents torque fluctuations greater than ±20%. For drives where torquefluctuations are greater or where the operation is near a serious critical or torsional vibration,a mass elastic study is necessary.4 or 5 6 or moreTable 1 S.F. 1,0 1,25 1,5 1,75 2,0 1,0 1,25 1,5 1,75 2,0Engine S.F. 2,0 2,25 2,5 2,75 3,0 1,5 1,75 2,0 2,25 2,5To use Table 2, first determine application service factor from Table 1. Use that factorto determine ENGINE Service Factor from table 2. When service factor from Table 1.is greater than 2.0 or where 1, 2 or 3 cylinder engines are involved, refer completeapplication details to our Application Engineers for engineering review.6SERIES XSELECTION PROCEDUREAlphabetical listing of applicationsServiceFactorAGGREGATE PROCESSING,CEMENT, MINING KILNS;TUBE, ROD AND BALL MILLSDirect or on L.S. shaft ofReducer, with final driveMachined Spur Gears .................... 2,0Single Helical orHerringbone Gears ......................... 1,75Conveyors, Feeders, Screens,Elevators ....................
