Notes
Gates PowerGrip Timing Pulleys are measured by number of grooves, pitch and width. For
example, TL30L050 denotes “TL” for Taper-Lock®, 30 grooves, L (.375”) pitch and 1/2” width.
Pitch-The pitch of a PowerGrip Timing Pulley is the distance from center to center of the
grooves (in inches). The letters correspond to pitches as follows:
MXL = Mini Extra Light = 0.080” pitch
XL = Extra Light = 0.200” pitch
L = Light = 0.375” pitch
H = Heavy = 0.500” pitch
Width-The width designation is in hundreths of inches and corresponds to the width of the widest belt that can operate in the pulley.
The complete pulley designation must be used when ordering a Gates PowerGrip Timing Pulley.
Abbreviation used for pulley bore: MPB = Minimum Plain Bore. Abbreviations used for pulley materials: AL = Aluminum ST = Steel
SiS = Sintered Steel GI = Gray Iron DI = Ductile Iron
MXL and XL MPB pulleys are supplied with set screws. L and H pulleys are not supplied with keyway and set screws.
