Belt Width Selection Tables – 3mm PowerGrip GT Belts
The following table represents the torque ratings for each belt in its base width at the
predetermined number of grooves, pitch diameters and rpm’s. These ratings must be
multiplied by the appropriate width factor and applicable belt length factor to obtain the
corrected torque rating (See Step 4 of Drive Selection Procedure on Page 16.)
