The N10 belt and pulley system which features an offset conical projection profile on the bearing surface to ensure positive fit without the need for guiding aids such as pulley flanges, even for narrow belts. These new 10 mm pitch belts are nondirectional in that they have the same meshing performance in both directions of belt travel. They are also polygon-free in that they are smooth when rolling around pulleys, thanks to contact with flat belt area. In addition, they minimize noise and vibration plus offer a homogenous distribution of forces in the belt to ensure that no force components act laterally, due to their symmetrical cone geometry and balanced tension member arrangement. They are made from polyurethane and are reinforced with steel tensile-cords for added strength. These belts are stocked in both double-and triple-row configurations in endless belt lengths from 500 mm to 1000 mm lengths. Belt stock is also available in 50 meter lengths. Three Conidrive™ mounting plates are also stocked. Conidrive™ pulleys are stocked in single-, double- and triple-row types featuring nonchordal action. They incorporate the patented Fairloc® integral hubs. The Fairloc® non-marring shaft hub consists of two slots that are machined into the hub, one radially the other angularly, to create a transverse wedge which remains attached to the solid portion of the hub on one side. The resultant cantilevered clamping section has a tapped hole to accept a cap screw which passes through a clearance hole in the solid portion of the hub, and into a threaded hole in the transverse wedge section.
