Roller chain sprockets, sometimes called single-strand sprockets, have a series of the teeth around a central bore and so are used in combination with roller chains to move conveyors and other industrial machinery. Fixed bore cogs and chains sprockets are created to fit a specific shaft size and include a keyway and setscrew therefore they’re ready to install. Basic bore sprockets are produced with out a keyway or established screw. Keyways or established screws can be machined to the precise size needed by the prevailing shaft and app. Bushed bores have significantly more clamping area around the shaft to supply a secure fit for high torque or high-power applications when the shaft is at risk of slipping, such as for example paper milling and agricultural machinery.
