A 6M 7-12-004 is a single-strand, self-lubricating roller chain with a 0.1227-inch pitch, made of black acetal resin, designed for low-torque instrumentation drives such as pen carriages and X-Y plotters. It has an operating temperature range of -40°F to +250°F with sustained use above +180°F not recommended, and supports speeds up to 1000 feet per minute with 8-tooth sprockets. The chain operates under running tensions up to 2 lbf and weighs approximately 1 oz per 15 feet. Its unit-link design allows adjustable length via snap-together assembly without a connecting link. The 004 length code specifies a 4-foot segment. The chain is 100% inspected for break strength, dimensions, and flexibility. Sustained static tension and torque overloads 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.
