Megadyne manufactures J, L and M section multi-rib V belts for use in high speed and  high ratio drive applications.  Constructed with polybutadiene rubber and polyester cords, our belt flexes around small drive pulleys allowing for high ratio drives to be used in  compact drive package design.  Multi-V Rib belts run quiet and deliver low vibration and will not turnover at high speeds. Fabric is added to the belts back side to increase lateral stiffness.
