Description
The 12B-2R Double Strand Metric Roller Chain is a B Series roller chain designed for power transmission and conveying applications that use metric chain dimensions. Commonly found in European and internationally manufactured machinery, these chains are used across industrial equipment, conveyors, processing systems, and other machinery requiring 12B-2R metric roller chain.
Unlike standard ANSI roller chains commonly used in North American equipment, B Series metric chains follow a different dimensional standard. Double strand construction provides increased load capacity compared to single strand chain while maintaining the same metric dimensional standard. Although some ANSI and metric chains may share the same pitch, dimensions such as roller diameter, inner width, and plate dimensions can differ, making them generally non-interchangeable. Always match the chain size and dimensions to the existing chain and compatible sprocket before ordering.
