Roller chain sprockets, sometimes called single-strand sprockets, have a series of teeth around a central bore and so are used in combination with roller chains to go conveyors and other industrial machinery. Fixed bore sprockets are created 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 set cogs and chains screws can be machined to the precise size necessary by the existing shaft and program. Bushed bores have more clamping region around the shaft to supply 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.
