* Recommend only 25% of rated torque on PTO’s (in.lbs.) - 30% with heavy duty disc.
Note: For mounting, use socket head capscrews conforming to the ASTM-574-97a.
Support plate must be perpendicular to sideload pull.
Estimated Side Load Calculation
#1 L =
126,000 x HP
x F x SF
N x D
#2 L =
1,945,000 x kW
x F x SF
N x D
L = Actual Applied Load (lbs. for #1 and
Kgs for #2)
N = Shaft Speed (RPM)
D = Pitch Diameter (in. for #1 and mm
for #2) of Sheave.
F = Load Factor
1.0 for Chain Drive or Gear Drive
1.5 for Timing Belts
2.5 for All V-belts
3.5 for All Flat Belts
SF = Service Factor
2.1 for Reciprocating
Compressors and other severe
shock drives
1.8 for Large Inertia Drives such as
Crushers, Chippers, and Planers
Note: Derate by 20% for 2,100 RPM.
