The A 6M 7-12 is a single-strand, self-lubricating plastic subminiature roller chain with a 0.1227 inch pitch, molded from black acetal resin for use in instrumentation drives such as pen carriages, X-Y plotters, and counter systems. It operates between -40°F and +250°F, with sustained temperatures above +180°F not recommended. The chain supports speeds up to 1000 feet per minute with 8-tooth sprockets and has a weight of approximately 1 oz per 15 feet. It features a unit-link design that allows adjustable length without a connecting link, and each link is inspected for minimum 7 lbf break strength. Service life is approximately 3.3 million cycles under 8 ozf running tension and 0.85% maximum elongation. Static tension applications, such as with spring-loaded idlers, are not recommended.
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.
