Nominal input power in kW at the stated input speed. n₂ is the nominal output speed at 1500 rpm input. Consult J.S. Gear for application-specific selection.
Output shaft loading
Permissible overhung load on the output shaft is 30 kN, acting at the middle of the shaft extension (L/2). Above this, support the drum on its own shaft and bearings with a flexible coupling, or use the standard gear ring below.
