A sprocket-wheel or chain-wheel is a profiled wheel with teeth that meshes with a chain or indented material. The name ‘sprocket’ applies generally to any wheel upon which radial projections engage a chain passing over it.
Multi-strand sprockets are used where higher torque and power are needed, or where two or more items are being powered by a common drive shaft. Available in Single Strand (Simplex), Double Strand (Duplex), Triple Strand (Triplex), Quadruplex.
Qd (quick disconnect) sprockets
Qd sprockets are used where higher working loads and high clamp loading on the shaft is desirable. They are flanged and use anchor bolts around the circumference. Sprockets with tapered bushings are easy to install and remove, provide clamp force, and align the sprocket.
Taper-lock sprockets
Taper-lock sprockets utilize a split through the taper and flange to provide a true clamp on the shaft. A taper-lock bushing is retained to the sprocket with set screws. They offer flexibility by allowing multiple sized bores for a single bushing size.
Double single sprockets
Double single sprockets are used in applications where two or more items are powered by a common drive shaft. The space between the plates is wider than a multi-strand sprocket and allows two separate strands of chain to engage without contacting the other. One strand may exit in a different direction than the other.
split sprockets
Steel split sprockets are split through the entire radius for easy installation and removal. The halves are held together by bolts. This style is available in pitch sizes 40 through 240, and bore diameters of 3/4 through 6 in.
Idler sprockets
Idler sprockets are used where the chain may experience slack due to long lengths, where there is a non-adjustable drive shaft, or where the chain has been guided around an obstruction. Using idler sprockets prevents chain whipping and uneven load distribution.
Conveyor sprocket
Conveyor sprockets (mill sprockets, engineering class sprockets, engineered sprockets) are used in conjunction with conveyor chains or conveyor belts. They are toothed gears or profiled wheels that mesh with a conveyor chain or belt to transmit rotary motion.
