Belt-drive system - TB Wood’s Inc

The QT Power Chain II belt-drive system consists of a synchronous belt, sprockets, bushings, and idlers designed to work together in low or high-speed applications. The new sizes of belts and sprockets along with increased power ratings (up to 40% higher than its predecessor) allow these systems to be designed in narrower and more-compact widths than before.

The body and teeth of the system’s belts are made of a durable polyurethane compound, specially blended for adhesion to the tensile cords and heavy nylon tooth facing, making the belt virtually immune to abrasion and chemical attack. Aramid fiber-tensile cords give the belts their strength to perform flawlessly under the harshest operating conditions. With no metal-to-metal contact between belt and sprocket, sprocket life increases over roller chain sprockets by a ratio of 10:1.
