A 6M 7-121508 is a subminiature plastic roller chain sprocket with 15 teeth, a 1/4 inch bore, and a 0.1227 inch pitch, molded from black acetal resin for nonmagnetic, self-lubricating, and nonconductive operation. It has a pitch diameter of 0.586 inch, an outside diameter of 0.650 inch, and a root diameter of 0.526 inch, with spoke dimensions of 0.846 inch and 0.746 inch for a two-spoke design. The bore is sized for press fit on a 1/4 inch shaft, and the E dimension is 0.312 inch. The sprocket is rated for use with standard chain of the same pitch and has a +0.000/-0.010 inch tolerance at 75°F.
Chain and sprocket drives are often used where positive synchronization between shafts and transmission of substantial torque are required. They are one of the more frequently used methods of power transmission, providing greater power than belts. Highly efficient, a single chain can drive several shafts and is used for both long and short distances. Adverse conditions, such as temperature and environment, do not affect their running. Other advantages include compact size and low maintenance costs. Chain drives are found in a wide range of power transmission applications, including bicycles, agricultural machinery, machine tools, conveyors, business machines, electronic or electro-mechanical devices, etc.
