    FALK A+PLUSSite proven drives for the most demanding applications

    Falk A+Plus parallel-shaft drives feature super-rugged designs tomeet every operating challenge. And theyre site-proven in the

    worlds most demanding applications to take plenty of tough, on-the-job punishment.

    Application-engineered to maximize strength and minimize wear,and to extend service life, these drives deliver steady, trouble-freeoperation, day-after-day. Theyre also specially designed and constructed to offer you maximum features and flexibility.

    A+Plus Smart FeaturesFALK MAGNUM NO-LEAK SEALS Falks exclusive labyrinth-design,non-wearing Magnum seal keeps oilin and dirt out. A purgeable greasechamber with, in most cases aViton contact seal, prevents theinfiltration of dirt and grime. Aunique drainback passage combineswith a radial and axial bush seal toretain oil and eliminate leaks.Tandem lip type seals are used forhigh oil level requirements.Manufacturers seal numbers arepublished for local sourcing.

    FALK SUPERIOR HIGHSTRENGTH GEARING A+Plus gearing is engineered to exceedAGMA requirements. Coarse pitchhelical gears (25 pressure angle)are protuberance hobbed, case carburized, and finish ground withlead and profile modifications thatassure full contact under load.These modifications, when combined with housing bore accuracy and assembly quality, provide gear mesh performance thatis equivalent to gearing with a

    quality 12 level. Spiral bevel gearsare case carburized, shot peenedand finish skived. A+Plus gears cantake the shock, where others fail.

    A+PLUS MESH ACCURATE QUIETOPERATION A+Plus advanceddynamic design, superior manufacturing and assembly

    standards, andstringent quality con-trols develop mesh-accurate gearing that assures exceptionallysmooth and quiet operation andextended service life.

    A+PLUS TOUGH STEEL HOUSINGSA Falk exclusive. Rugged, all-welded steel housings simplifyrebuild or bearing replacement.Extra strength and rigidity tomaintain accurate gear alignments.

    REDUCED DOWN TIME At 200F(93C) Falk A+Plus Viton oil-sealshave 18 times the operating life ofconventional Nitrile seals.

    LOWER COSTS A+Plus standard features significantly reduce long-term costs of maintenance andrepair downtime.

    Factory Warranty Were so confident in the performance andreliability of our latest generation of Falk gear drives that werebacking this comprehensive offering with the best standardwarranty in the business. Our full, 3-year Heavy-Duty Warrantyprovides shaft-to-shaft protection on all Falk components including bearings and seals. Its an industry first... and one more powerful reason why Rexnord is your ultimate bottom-line driveand coupling value.H

    Safety NotesFalk Gear Drives The Falk and Rexnord name on the geardrive is the purchasers assurance that the drive was engineered,rated and manufactured to sound design practices.

    The power supplied to the geared drive must be equal to or lessthan the power for which the drive was selected using theappropriate service factor for the application. The customer mustassume the responsibility of isolating the geared drive from anyvibratory or transient load induced by the driven equipment.

    Install and operate Rexnord products in conformance withapplicable local and national safety codes and per Rexnordinstallation manuals which are shipped with gear drives and arealso available upon request. Suitable guards for rotatingmembers may be purchased from Rexnord as optionalaccessories. Consult your local Rexnord district office forcomplete details.

    People Conveying Equipment Selection of Rexnord gear drivesfor applications whose primary purpose is the transportation ofpeople is not approved. This includes such applications as freight or passenger elevators, escalators, man lift platforms and skitows and ski lifts.

    If the primary purpose of the application is material conveyanceand occasionally people are transported, the Rexnord warrantymay remain in effect provided the design load conditions are notexceeded and certification to the appropriate safety codes andload conditions has been obtained by the system designer or end user from the appropriate enforcement authorities.

    Gear Drive Ratings All gear drive ratings in this selection guideallow 100% overload for starting loads and momentary overloadsfor electric motor driven applications operating 10 hours per dayunder uniform conditions (unity Service Factor). For other conditions, compute an equivalent power by multiplying the actual powerrequired for the application by the appropriate Service Factor.

    Power and Torque Gear drive mechanical power and torqueratings are tabulated in the selection guide to permit selections forspecific application requirements. When the required input speedfalls between two tabulated input speeds of a drive with the samenumber of gear reductions, interpolate to determine drive rating.

    Thermal Ratings must be considered when selecting a geardrive. Refer to Page 10 for more information.

    Stored and Inactive Drives Each gear drive is spin-tested witha rust preventive oil that will protect parts against rust for aperiod of 4 months in an outdoor shelter or 12 months in a drybuilding after shipment from the Factory.

    Periodically inspect stored or inactive drives and spray internalparts with rust inhibitor every six months or more often, ifnecessary. Drain oil before adding rust inhibitor. Indoor drystorage is recommended.

    Drives ordered for extended storage can be treated at the Factory with a special preservative and sealed to rust-proof parts forperiods longer than those cited above, if specified on the order.

    Refer to appropriate service manual for extended storage of gear
