PowerGrip ® HTD ® Belt Drives
Belt Width Selection Tables – 5mm PowerGrip HTD 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.
rpm of Faster Shaft
Belt Width (mm) 9 15 25
Width Multiplier 1.0 1.89 3.38
