Usually, the BS wide spiral belts are driven by smooth (steerable) cylindrical rollers. For light applications, there is the BS 5-6.4/0.9-1.2. This belt also has the ability to be powered by small pin sprockets. These pin sprockets normally have an outer diameter of 50 mm and fit exactly into the belt. The distance of the sprockets on the shaft is recommended at approx. 100 mm.
​
Although the tolerances in the belt are very small, each belt is unique. The pin sprockets must be mounted in line (key). The small number of teeth can easily accommodate the internal tolerance in the longitudinal direction of the belt (pitch is 6.4 mm). Caution is advised in the width of the belt (pitch 5 mm). A belt of approx. 1000 mm width already has 200 turns. It is important that the exact position of the pin sprocket (left/right on the axle) is determined by the belt itself so that it can be placed without forcing. This applies not only to new belts in new installations, but especially to replacement belts on existing wheels.
​
Wide spiral belts with side chains are recommended for wide or heavily loaded spiral belts that require positive / controlled drive. The side chains (in many sizes) give the belts greater stability and better steering. The chains can be driven by standard (DIN/ASA) sprockets.
