Timing belt drives

Self-guiding Conidrive timing belt drives feature the N10 belt-pulley system with an offset conical projection profile on the bearing surface to ensure positive fit without pulley flanges, even for narrow belts.

Features & benefits

  • Nondirectional 10-mm pitch belts offer same meshing in both directions of travel

  • Polyurethane, reinforced with steel tensile-cords for strength

  • 500 to 1.000-mm lengths; belt stock also available in 50-m lengths

  • Single, double, triple-row types featuring nonchordal action

  • Fairloc integral hubs create a transverse wedge that remains attached to the solid portion of the hub on one side
