The A 6M 7-12-050 is a 0.1227-inch pitch, single-strand, self-lubricating roller chain made of black acetal resin, designed for low-torque instrumentation drives such as X-Y plotters and recorders. It measures 50 feet in length and weighs approximately 1 oz per 15 feet. The chain operates within a temperature range of -40°F to +250°F, with sustained use above +180°F not recommended. It supports running tensions up to 2 lbf and speeds to 1000 feet per minute with 8-tooth sprockets. The unit-link design allows adjustable length without connecting links, and 100% inspection ensures minimum momentary break strength of 7 lbf, with pitch, thickness, and flexibility verified. Elasticity under load is specified, with service life estimated at 3.3 million cycles under 8 ozf tension and 0.85% elongation. Static tension and torque peaks must be limited.
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.
