Approx. Weight Per Rib – 0.019
Multi-Rib V-Belts – J, L, M
Where 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.
