Roller chain sprockets, sometimes called single-strand sprockets, possess a series of teeth around a cogs and chains central bore and so are used in combination with roller chains to move conveyors and other industrial machinery. Fixed bore sprockets are made to fit a particular shaft size you need to include a keyway and setscrew so they’re ready to install. Simple bore sprockets are produced with out a keyway or set screw. Keyways or arranged screws can be machined to the exact size needed by the prevailing shaft and software. Bushed bores have more clamping region around the shaft to supply a secure suit for high torque or high-power applications when the shaft is at risk of slipping, such as for example paper milling and agricultural machinery.
