The A 6M 7M12 is a single-strand, self-lubricating roller chain with a 3.12 mm pitch, made from black acetal resin, designed for light-duty power transmission in applications requiring adjustable length and snap-together assembly. It operates between -40°C and +121°C, with sustained temperatures above +82°C not recommended. The chain supports running tension loads up to 0.91 kgf and can operate at speeds up to 5.1 m/sec with 8-tooth sprockets. Its approximate weight is 0.031 kg per 5 meters. The unit-link design allows adjustment without a connecting link, and either side may engage sprockets. Maximum momentary break strength is 3.2 kgf, and elongation under load is characterized in a tension-elongation table. 100% inspection ensures compliance with pitch, thickness, width, and flexibility tolerances.
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.
