All Variable Speed V-Belts are of the Wrapped & Cogged type. They are also known by the name of Multi Speed belt and exhibit a different shape than the normal V-belts. Its top width is greater than its thickness. Such a difference in shape enables these belts a greater range of speed ratio than any standard belt.
DURATUF Variable Speed belts deliver the required speed & horsepower. They are flexible, prevent buckling at minimum diameter settings where the belt stresses are greatest. Its firm gripping action in the contact area provides positive traction for precise, immediate response. Together, they assure reliable, predictable transmission of maximum power over the drive’s full operating range. Their better performances confirm lesser downtime for belt maintenance & much more productivity for customers’ equipment.
Usually, cogged or notched on the underside of Variable Speed belts are specified for equipment which requires changes in driven speed during operation. Variable Speed belts are specified by top width, inner circumference and the required groove angle. The groove angle can be measured from the drive pulleys.
