Emerson Industrial Automation (Florence, KY) offers Morse Raider Plus speed reducers that use finishing techniques, additional bearings, and special seals to arm them for leak-free performance. For use with conveyors, mixers, and bucket elevators, the device’s computerized gear centering optimizes the gear mesh for reduced heat and debris formation. A patented roll-burnished journal finish extends seal life, and double-lip seals on both input and output shafts provide leakproof operation in highly contaminated applications. The speed reducer features a non-metallic quill liner that reduces fretting and corrosion, and eases motor removal.

Large, single-row ball bearings absorb radial and thrust loads on higher input speeds, and tapered roller bearings on all output shafts handle inherent gear load and provide maximum overhung load capacity. Four unit models — the “U,” which is a universal style with an output shaft; the “Q,” which is a c-face-style with an output shaft; and both styles with hollow outputs — are available with a center distance range of 1.0 to 6.0", ratios from 4:1 to 3600:1, and output torques from 82 to 22,416 ft-lbs. Housings, motor adaptors, covers, and mounting bases have cast iron, single-piece construction. The integral worm and shaft are hardened to 58RC. The speed reducers are all factory-filled with FDA-approved polyglycol synthetic lubricant for reduced thermal rise.
