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 -
Example: 445J6
