Split sprockets with keyways are ’
tight fit’ onto the shaft and can be used for belt widths up to 680 mm and
temperature differences of max. 30°C. For wider belts or bigger temperature differences, square bores have to be used.
Square sprockets can be used on the drive- and on the idler shaft. They ‘float’ freely on the shaft.
