Presentation - These reducers are available with hollow or standard output shafts with diameters from 70 to 180mm, in casing made of cast iron, GS cast iron or cast steel. - Ratios range from 5 to 60. The fact that they may be coupled together means that an extremely wide range of output speeds may be obtained. - Output shaft diameter from 70 mm to 180mm - Works as a reduction gear or step-up gear - Weight from 130 kg to 2 tons Advantages Silent The principle behind the way worm gears work, by teeth creeping, combined with a high drive ratio, results in the lowest noise level of all gear transmission systems. Compact For many applications, having a compact reducer is essential. DURAND reducers have been designed to reduce size: - Orthogonal layout of shafts - Hollow shaft assembly - High ratios in a small size Robust An extremely rigid casing and the use of high quality components with well sized dimensions ensures extremely robust units. DURAND reducers can transfer high torque without requiring a lot of space.
