Roller chain sprockets, sometimes called single-strand sprockets, possess a series of teeth around a central bore and are used in combination with roller chains to move cogs and chains conveyors and other commercial machinery. Fixed bore sprockets are designed to fit a specific shaft size and include a keyway and setscrew therefore they’re ready to install. Plain bore sprockets are manufactured without a keyway or arranged screw. Keyways or set screws could be machined to the exact size necessary by the prevailing shaft and software. Bushed bores have more clamping region around the shaft to provide a secure match for high torque or high-power applications when the shaft reaches risk of slipping, such as for example paper milling and agricultural machinery.
