Notes to REDUCER SERVICE FACTOR tabIe:
1) Service factors for paper miII appIications are
applied to the nameplate rating of the eIectric motor
at the motor rated based speed.
2) Anti-friction bearings onIy. Use 1.5 for sIeeve bearings.
3) A service factor of 1.0 may be applied at base speed
of a super caIender operating over-speed range of
part range constant horsepower, part range constant
torque where the constant horsepower speed range
is greater that 1.5 to 1. A service factor of 1.25 is ap-
pIicabIe to super caIenders operating over the entire
speed range at constant torque or where the con-
stant horsepower speed range is Iess than 1.5 to 1.
