SERIES J SELECTION PROCEDURE Definition of service factor The torque ratings apply to service factor fb = 1.0. The service factor fb = 1.0 gives continual operation 4 to 8 hours a day at a uniform load without shocks and with 10 to 200 starts an hour. The moment of inertia of the driven machines is less than 20 % of the electric motor inertia and occasional peak torque may not exceed 1.8 times the torque rating. For other running conditions compensate with service factors according to tables. Mechanical Rating Determine the demand of power (Pe kW) or torque (Te Nm) and speed (ne min -1 ) to...

Please note: Dimensions R, T, T1, T2, T3 are not machined, deviations can occur. 1. The V-belt pulley should be placed as close to the housing as possible. 2. These dimensions are minimum diameters of driven pulley to prevent overloading of the bearings. 5. The reducer should normally be mounted on a shaftwith tolerance ISO js6. On heavy duty applications closer tolerances are recommended. 8. Space for spacer if locking ring is used.
