Rubber Multi Rib BeltWhere a broad range of speed ratios (up to 60:1) is required, Multi-Rib V-belts are often recommended. Belt turnover is eliminated. Additionally, Multi-Rib V-belts offer greater flexibility than banded V-belts for smaller pulley diameters and more compact drives. Greater belt rib to pulley groove contact gives more power transmission in less space. Multi-Rib V-belts are also available in polyurethane construction on special order. For K section automotive and other sizes not listed, consult Jason/Megadyne.

Multi-Rib V-belts conform to ARPM Engineering Standard IP-26 and ISO 9982. Multi-Rib V-belts are specified by the effective length in inches multiplied by 10, the cross-section and the number of ribs – Example: 445J6

Features & Benefits
