HUBATTACHMENTTOTHESHAFT–BOREANDKEYWAY
1. Inspecttheshaft,hubbores,andkeywaystomakesurethattheyarecleanandfreeofburrs.Lightlyoilingthe
shaftwillmakeiteasiertoassemblethehubontheshaft.
2. Placethehubontheshaft.Besuretoslidethehubfarenoughontotheshaftsotheshaftendisevenwith
thehubface.ThisshouldnotbechangedwithoutconsultingReichUSACorp.Thedistancebetweenshaft
ends(DBSE)willthenbethewidthoftherecommendedspacebetweentheassembledcouplinghalvesforthe
HBSX‐RHconfiguration(seedimensionL2inFigure1andTable1).
3. Standardhubsaresuppliedwithaslightclearancefit.Itisrecommendedforhubswithboreslargerthan3”
(76mm),usinganinterferencefitorspecialtorquetransmittinglockingdevices.Forhubswithinterference
fits,uniformlyheatthehubtoamaximumof248– 266oF(120‐130°C)andquicklyassembleontheshafts.
Theuseoftorchesorrosebudsisnotrecommendedbecausethiscancausehighstressesandpermanent
distortions.
4. Fitthekeyintothehub.Ifsuppliedwithasetscrew,turnthesetscrewuntilthetopofthekeyiscontactedin
thehub.
5. Afterfollowingthecouplinginstructionsforaxialalignment,usethecorrect‘HubInstallationinstructions’for
thesecondhub.
ReichUSArecommendsstartingthecouplingassemblyby
mountingthehubsand/oradaptersthatareboltedtothe
centerspacerassemblyontotheinputandoutputshaftsfirst.
Mostofthetimethiswillprovideaccurateperpendicularand
concentricsurfacesforaligningthepartsconnectedbytheR‐
Flexcoupling.
Forstandardboreandkeywayhubs,thehubshavetobe
assembledsothatthehubflangefaceisalignedwiththe
shaftend.Thedistancebetweenshaftends(DBSE)willthen
bethewidthoftherecommendedspacebetweenthe
assembledcouplinghalvesfortheHBSX‐RHconfiguration
(seedimensionL2inFigure1andTable1).

HUBATTACHMENTTOTHESHAFT– SHRINKDISC
1. Inspecttheshaftandhubboresthattheyarecleanandfreeofburrs.DONOTplaceanygreaseontheshaftor
insideofthehubasthiswillnotallowtheneededcoefficientoffrictionbetweenthehubandshaft.The
contactsurfacebetweenthehubandinnerringoftheshrinkdisccanbelightlyoiledforassembly.Forlarger
shrinkdiscs,theinnerringisprotectedwithoiledpaper,whichmustberemovedbeforeassembly.Makea
quickinspectionthattheShrinkDiscscrewthreads/headandtaperedinnerringarecoatedwithgrease.If
not,pleaselubricatethesesurfacesonlywithMolykote Grease.
2. Placetheshrinkdiscontothehubbeforeinstallingthehubontheshaft.
3. Assembletheshrinkdisc/hubontotheshaft.Slidethehubfarenoughontotheshaftsotheshaftendiseven
withthehubfaceortotheminimumrecommendedshaftdepthperthesuppliedcouplingassemblydrawing.
TheminimumshaftdepthshouldnotbechangedwithoutconsultingReichUSA.Thedistancebetweenshaft
hubswillthenbethewidthoftherecommendedspacebetweentheassembledcouplinghalvesfortheHBSX‐
RHconfiguration(seedimensionL2inFigure1andTable1).
4. Hand‐tightentheclampingscrews(figure2,item5)untiltheshrinkdiscsitsonthehubandthegapbetween
thepressurerings(figure2,items2and3)areeven.
5. Setthetorquewrenchtotherecommendedshrinkdiscscrewtorque.Begintorqueingthescrewsina
clockwiseorcounterclockwisemanner.Donotturnanyscrewsmorethan90degreesatonetime.Thiswill
helpinsurethatthegapbetweentheouterringsremainsasevenaspossible.Installationiscompletewhen
allscrewsareattherecommendedshrinkdiscbolttorque.
6. Afterfollowingthecouplinginstructionsforaxialalignment,usethecorrect‘HubInstallationinstructions’for
thesecondhub.

MACHINERYALIGNMENT
ReichUSAR‐flexcouplingscantoleratemisalignmentsthatvarywiththenumberofdiscpackbolts.Forexample,a4‐
boltcouplingallowsamaximumangularmisalignmentof1°,whereasan8‐boltcouplingallowsamaximumangular
misalignmentof0.5°.Misalignmentunderworkingconditionscanchangeduetomanyfactors,suchasthermal
growth,magneticcentering,andsettlingofthecoupledcomponents.Carefulinitialalignmentwillpermitthecoupling
tooperateatfullcapacityandallowforsomefutureoperationalmisalignments.Theinitialmisalignmentvaluesin
Table1areforgeneraluseandcanvaryinspecificcases.Afterhavingproperlyalignedthecoupling,makesurethat
alltheboltsandnutsaretightenedtotheirpropertorque.Ifpossible,itisagoodideatocheckthetorqueaftersome
hoursofoperationaswell.

AxialAlignment
Inordertoensurepropercouplingoperationandcouplinglife,itisrecommendednottoexceedthelimitsin
Table1unlessotherspecificinstructionsaregivenforspecialcouplingapplications.
Toperformtheaxialalignment:
1. Bringtheequipmentintothebestvisualalignmentpossible.
2. Positionthehubsaxiallysothatthedistancebetweenshaftendsiswithintheminimumand
maximumdimensionsL2±aSeeFigure1andTable1forreference.
Fornon‐standardcouplings,seeinstructionsonthecorrespondingcouplingdrawing.

AngularAlignment
1. Withadialindicatororlasersystemmeasuretheangular
misalignmentbydeterminingtheparallelismofthe
couplingflangefaces.
2. Dimension,asshowninFigure3,shouldbemeasuredin
atleastthreepoints,equallyspaced,todeterminethe
maximumvaluefor.Thismustnotexceedthe
maximumallowabledimensionstatedinTable1.
3. Adjustorshimtheequipmenttobringeithertheindicator
readingorthemeasuredandcalculatedflangegapwithin

tomeasuretheapproximatedistancep.Amoreprecisemethodistouseadialindicatororlasersystem
andmeasuretheparalleloff‐setinatleasttwolocations90 degreesapartwhilerotatingthehub(see
Figure5).
