For applications up to 250kNm, Nord Drivesystems provides robust industrial gear units which it says "Are characterised by high power density, quiet operation and reliability". The modular system with multiple options also provides machine builders with a high level of design flexibility. MAXXDRIVE industrial gear units deliver output torques from 15 to 250kNm and are said to be well suited for use in heavy-duty applications such as agitators, belt drives, mixers, mills, drums or crushers. A torsionally-rigid, single-piece UNICASE housing is said to help achieve a longer bearing life than gear casings manufactured from jointed parts, and large, low-friction rolling bearings are used to cope with high axial and radial loads over a long service life. The company offers these industrial gear units as either parallel or right-angle versions which cover popular speed ratios from 5.54:1 to 400:1, and can go up to 30.000:1 with an auxiliary primary stage gear unit.
