Emerson Morse Raider Plus' roll-burnished seal journal and double-lip seals guarantee leak-free operation for 18 months.

Emerson Industrial Automation introduced its Morse Raider Plus speed reducers that feature additional bearings and special seals to keep them leak-free for 18 months, the company says. The reducer features computerized gear centering, a patented roll-burnished journal finish and double-lip seals on both input and output shafts. The Raider Plus also features a non-metallic quill liner as well as single-row ball bearings and tapered roller bearings on all output shafts.

The reducer line is available in four unit models. The universal “U” style and c-face “Q”-style — both available with hollow outputs – feature a center distance range of 1.0 to 6.0 inches, ratios from 4:1 to 3600:1 and output torques from 82 to 22,416 ft-lbs. All Raider Plus housings have cast iron single-piece construction with forged bronze worm gears, manufactured to AGMA specifications and hardened to 58RC. The speed reducers are all factory-filled with FDA-approved polyglycol synthetic lubricant.
