Flat Belts Increase Motorized
Round belts usually limit powered motorized roller zone length to a maximum of 10 rollers because the belt's thin area of roller contact limits the amount of torque that can be transferred before round belts begin to slip. Wide urethane flat belts do not have this limitation, so slipping is virtually eliminated.
Therefore, zone lengths of 20 or more rollers are possible. In fact, except for extremely heavy boxes, the only thing that limits zone length is the torque of the motorized roller. Since our wide flat belts are elastic, they do not need belt tensioners, so they can be retrofitted onto conveyors without changing rollers. Our flat belts are more economical than our Poly-V® multi-ribbed belts because they do not need grooved rollers. However, Poly-V belts are better at moving extremely heavy loads, even pallets, at very high speeds. For more information click here.

Due to larger mass, wide flat belts are stretched much less than round belts. For example, our 1/16" (1.6mm) thick x 4" (100mm) wide belts are typically stretched 3.3%. Please use our belt tension calculator
