Description:
The E series is a range of coaxial gear reducers and gearmotors combining the traditional qualities of coaxial gear reducers – compactness and economy – with modern design and manufacturing criteria. The MR 31 80 UC2A – 49.7 features a rigid and precise single‑piece cast iron housing, universal mounting with lower and upper feet and B5 flange integral with housing (excluding sizes 32…41). It incorporates generously proportioned bearings on the low speed shaft to withstand high loads, and a pinion of the final reduction with three bearings (excluding sizes 32…41) ensuring best meshing conditions, maximum rigidity, and reduced noise. The gear reducer has a transmission ratio of 49.7, is designed for continuous duty S1, and offers high, reliable, and tested performances. It is suitable for a wide range of industrial applications including pumps, fans, shredders, mills, and conveyors.
