Below is a list of Sprockets manufacturers from Muskegon, Michigan. Sprockets are thin cylindrical wheels with toothed rims that, through the use of parts such as chains or tracks, function to transfer rotational force into motion. Sprockets are very similar to gears; however, the main difference between the two is that gears must be used in conjunction with other toothed parts to transmit motion, whereas sprockets transmit motion through perforated or indented materials.
