Twin Power® belts have precision-formed elastomeric teeth on both sides to provide high-loading capacity synchronization from both driving surfaces. Gates PowerGrip® Twin Power® Timing Belts are suitable for all industrial serpentine applications that require rotation reversal in some driven shafts.

  • Gates Twin Power belts have nylon facing on both tooth surfaces to provide equal load carrying capabilities on either side of belt.
  • Belt capacity is equal to standard single-sided PowerGrip Timing belts.
  • High efficiency positive drive.
  • High tooth jump resistance.
  • Fiberglass tensile cord provides high strength, excellent flex life, and high resistance to elongation.
  • Neoprene body provides protection against grime, grease, oil, and moisture.

  • Notes
    Belt Notes Abbreviations 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. Details shown which do not affect drive function or overall weight may be changed without notification. Gates PowerGrip® Timing Pulleys are measured by number of grooves, pitch and width. For example; part number TL30L050 denotes "TL" for Taper-Lock®, 30 grooves, L (.375") pitch and 1/2" width. MXL and XL MPB pulleys are supplied with set screws. L and H pulleys are not supplied with keyway and set screws. 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. The complete pulley designation must be used when ordering a Gates PowerGrip® Pulley. Width - The width designation is in hundredths of inches and co
    WARNING: Do NOT use these sprockets with rim speeds in excess of 6,500 fpm.

We're Taking Down Downtime.

Gates Twin Power PowerGrip Belts run quieter than roller chain drives and eliminate the need for lubrication and re-tensioning to reduce maintenance, downtime and labor in your operations.

Give Your Applications 100% on Both Sides, Without Compromise.

Twin Power® can transmit up to 100% of its maximum rated load from either side of the belt; alternatively, it can transmit a load on both sides – provided the sum of the loads does not exceed the maximum capacity.
