Improved transmission ratio (Poly-V 1:60 vs. V-belt 1:20)
Reduced diameters can be used.
Reverse bend application.
Reduced belt width for a given geometry and similar power transfer.
Provide a wide selection of speed ranges.
Multi-pull Poly-V belts have higher-power carrying capacity than conventional V-belts. Single flexible low stretch belt drive eliminates the need for multiple/matched set belts.
Polycotton fabric frictioned with Polychloroprene rubber.
Cushion rubber to stretch at the belt bend.
Tension member to carry power and minimise stretch.
Base rubber to support cords evenly and compress as the belt bends.
