Multi-Rib belts, like the Poly V® and Multi V®, feature lengthwise groove and provide superb drive by adhesion. Compared with conventional belts of the same width, Multi-Rib belts optimize the contact area, giving you increased power transfer. A thin cross section profile allows for use with smaller pulleys than standard V-belts.

Drive widths can be reduced because there is increased surface engagement allowing for increased horsepower per inch of belt width compared to standard V-belts. Even in specialty applications, this belt and pulley combination operates quietly and with minimal vibration.

  • Precise Power Per Rib - power can range from a few hundredths of a horsepower up to 1.7 hp per rib
  • More ribs mean more power - increased horsepower per inch of belt width compared to standard V-belts
  • Pulley size puts precision in the power
  • Drives with 4, 6 or 10 ribs - popular industry standards
  • Several belts can ride on a single custom sized pulley
  • New belt designs improve performance on partial turns - as small as 1/4 or 1/8 rotation
  • Made in USA
