Emerson Industrial Automation’s Morse Raider Plus speed reducers utilize advanced finishing techniques,additional bearings and special seals to armthem for leak-free performance,guaranteed for 18 months. Ideal for conveyors, mixers and bucket elevators in the food, beverage and grain industries, the Raider Plus’ computerized gearcentering optimizes the gear mesh for reduced heat and debris formation, eliminating unnecessary backlash and delivering high efficiency and long life.A patented roll-burnished journal finishextends seal life up to four-fold, andexclusive double-lip seals on both input and output shafts provide leak-proofoperation in highly contaminated applications. The Raider Plus also featuresanexclusive non-metallic quill liner that reduces fretting and corrosion, andeases motor removal. Large, single-row ball bearings absorb radial and thrustloads on higher input speeds, whileheavy-duty tapered roller bearings on alloutput shafts handle inherent gear load and provide maximum overhung load capacity.

“Akey design component of this reducer is a second input bearing that reduceswear and fatigue on the input seal,” said DeWayne Polley, Gearing ProductSpecialist for Emerson.“The second input bearing minimizes shaft movementduring motor installation and operation. We tracked the performance of theRaider Plus and are confident the materials and assembly ofthis productsupport an 18-month leak-free guarantee.”


Fourunit models – the “U”: a universal style with an output shaft, the “Q”: ac-face-style with an output shaft, and both styles with hollow outputs – areavailable from stock with acenter distance range of 1.0” to 6.0”, ratios from4:1 to 3600:1 and output torques from 82 to 22,416 ft-lbs.


AllRaider Plus housings, motor adaptors, covers and mounting bases have cast ironsingle-piece construction for maximum strength and dependability. Forged bronzeworm gears,precision manufactured to AGMA specifications, provide greatertensile strength than cast bronze. The integral worm and shaft are hardened to58RC for extra strength and durability. Thespeed reducers are allfactory-filled with FDA-approved polyglycol synthetic lubricant for enhancedrating and reduced thermal rise.

A video demonstrating how the worm gear reducer all but eliminates irregularshaft movement that damages seals and causes leaks is available on the Emerson YouTube channel.
