Shaft Mounted Speed Reducer Manufactured & Supplied by JRB Engineering Works JRB Engineering Works is a trusted manufacturer and supplier of high-performance Shaft Mounted Speed Reducers (SMSR), designed to provide efficient speed reduction and high torque transmission for a wide range of industrial applications. Our shaft mounted speed reducers are engineered for rugged performance, compact installation, and reliable operation in demanding working conditions. The optigear Shaft Mounted Speed Reducer provides a very convenient method of reducing speed, since it is mounted directly on the driven shaft instead of requiring foundations of its own. It eliminates the use of one and sometimes two flexible couplings and external belt take-up arrangements. A torque-arm anchors the Reducer and provides quick easy adjustment of the V-Belts by means of its turnbuckle. The Optigear Speed Reducer is manufactured in eight gear case sizes, designated by the letters B to J. The eight sizes may have anyone of three nominal gear ratios 5: 1, 13:1 and 20: 1. These reducers are especially suitable for conveyor systems and material handling equipment where direct mounting on the driven shaft is required, eliminating the need for complex foundations and couplings. Robust Design & Efficient Performance The Shaft Mounted Speed Reducer from JRB Engineering Works features a compact and heavy-duty construction that allows direct mounting on the driven shaft. The reducer is supported by a torque arm that absorbs reaction forces, ensuring stable and vibration-free operation. Manufactured using high-quality cast iron housings and precision-cut gears, our speed reducers offer excellent strength, reduced noise, and high mechanical efficiency. Proper sealing and oil bath lubrication ensure smooth operation and long service life with minimal maintenance.
