December 14, 2010—

A new series of ultra miniature inch and metric 3.117 mm pitch molded chain drives from Stock Drive Products are designed for use where limited space and weight factors are important: such as servo drives to stylus or pen carriages in recorders and X-Y plotters, chart roll drives and counter drives. They are used in communication equipment, business machines, cameras and other electronic or electro- mechanical devices.

Made of pre-lubricated, non-magnetic black acetal, these drives, identified as the A 6M 7M12 series, are designed to
operate over a wide range of temperatures from -40 degrees C to +121 degrees C. The chain features a unit-link design that eliminates the need for a master link. Each unit-link measures 2.08 mm high and 4.12 mm wide. A length of 321 links snapped together will equal one meter and a length of five meters of chain weighs only 0.031 kg. Chain operating speeds of up to 5.1 meters per second, around smaller eight-tooth sprockets and maximum operating loads of up to 0.9 kg. of tension are recommended.

The A 6M 7M12 sprockets are stocked in 14 sizes from eight through 48 teeth. Three bore sizes are stocked for press fitting the sprockets to three, four and six mm shafts. Sprockets that have 24 or more teeth are molded with a spoked configuration. Outer diameters range from 9.4 mm (.371") to 49.3 mm (1.939") and pitch diameters from 8.1 mm (.318") to 47.4mm (1.865"). The A 6M 7M12 series is available for immediate delivery from SDP stock.
Quotes, online orders, and 3-D CAD models are available at our new eStore.
