Twisted belts are used as quick-fix replacement belts for round O-Ring drive belts. These are used on line-shaft conveyors as a quick and easy replacement for solid round o-ring bands. No need to drop the line-shaft to install these belts. For common 3/16" belts, twisted belts should be ordered 6% shorter than the round O-ring belts they replace. They are typically stretched 16-19% vs. 10-13% for O-ring drive bands. Stainless steel metal or plastic hooks available for most sizes. An installation tools is available. This is NOT an exhaustive list, twisted belts can be made from other polyurethane cord. If you dont see your belts on the list, contact us.
