Service life of ballscrew unitsThe ba llsc rew in motion unde r a n externa l loa d rece ivesrepea ted stress on its rac ewa ys and ba lls. When the

stress reac hes a certain point, the racew ays fatigue a ndeventually break, a nd their surfa ces peel. S uch peeling iscalled flaking.

The s ervice life of a ba llsc rew unit is the to ta l numbe r ofrevolutions that the unit achieves before the first flakingocc urs a s a res ult of the rolling fa tigue o f the rac ew a ys o rballs.

The s ervice life of b a llsc rew units varies g reatly from unitto un i t , even i f they a re manufac tu red to the samespecif ications and remain in service under the sameope rating c ond itions . Therefore, g uide lines for dete rminingthe se rvice life of a ba llsc rew unit a re g iven ba se d o n thenominal life, which is defined below.

The no minal life is the tota l numb er of revolutions tha t90% of identica l ballsc rew units in a group, whe n ope ra tedindepend ently of one a nother under the sa me co nditions,ca n a chieve without developing fla king.

Basic dynamic load rating C aThe b a sic d ynam ic loa d rating (C a) of the b a llsc rew is us edto c a lcula te its se rvice life when it is o perated under a load .

The b a sic d ynamic load rating (C a ) is the load with anonvarying direction and magnitude that makes the nominal

life L of identica l ballsc rew units in a group, w hen ope ratedindependently of one another, 10 6 (revolutions). (Basicdyna mic load rating Ca is pres ented in the c orres pondingdimension tables.)

The d ynamic load C a is ba sed on the ca lculation methoda cc ording to ISO 3408-5 resp ec tively DIN 69051 (1989).This ca lculation metho d is d efined by the Europea n a ndJ a pa nese b a llsc rew ma nufac turers as a universa lly validstandard.

Service-life calculation

The nominal life of the b allsc rew ca n be ca lculated by a neq uation (6) using the va lues for the b as ic d ynamic loadrating (C a) a nd a pplied a xia l loa d.

If the b allsc rew, w hether at rest or in motion, rece ives a nexces sive loa d o r significa nt impa ct, loca lized permanentdeformation develops b etween the racew ay a nd ba lls.

Over a certain level, the permanent deformation hinders thesmo oth movement of the ba llsc rew. Norma lly, the ba sicstatic load rating (C0a ) is ta ken as the permiss ible a xia l loa d.

Basic static load rating (C 0a )The ba sic sta tic load rating is the sta tic load with a non-varying d irection and ma gnitude that ma kes the sum o f thepermanen t d eformat ion o f the ro lling e lements a ndraceway 0.0001 times the rolling-element diameter. Withthe ballscrew, the basic static load rating is defined inrelation to the a xial load .

Va rious values for the b a llsc rew a re prese nted in thecorresponding dimension tables in this catalog.

Static safety factorThe b a sic s tatic load ra ting (C 0a ) is normally equal to thepermiss ible a xia l loa d of the b allsc rew. De pending on theoperating c onditions, use of a sta tic s afety factor such a sthat specified be low s hould be c onsidered. Please b e a wa rethat the ballscrew may receive an unpredictable externalforce due to vibration a nd impac t w hile it is at res t or in

motion, or due to inertia resulting from starting and stopping.

(4)Applied load and service life inconsideration of the preload

For a ba llsc rew used with a preloa d a pplied to the nut, theservice life should be calculated in consideration of thepreloa d, which is the internal loa d on the nut. If you ha veques tions a bout the preloa d, plea se c ontac t us, and be s ureto s pec ify the relevant mode l number.

(5) Mean axial loadWhen the a xial loa ds a pplied to the ba llsc rew fluctuate , theservice life should be c a lculated b a se d on the mean a xia lloa d of the va rying a xia l loa ds .

The me a n a xia l loa d (F m) is the loa d tha t ma kes the s ervicelife of the ba llsc rew eq uivalent to tha t under varying loa dsexerted during operation.

Dust and foreign matter that enter the ballsc rew ma y ca useac celerated wea r and breakage, as with rolling b earings.Therefore, w here c onta mination by dus t a nd foreign ma tter(e.g ., cutting chips) is likely, screw sha fts must alwa ys beco mpletely covered w ith conta mination protec tion de vice ssuch as bellows or screw covers. If the ballscrew is usedin an atmosphere free from foreign matter but withsuspended dust, the labyrinth seal (for Precision Ballscrews)and brush seal (for Rolled Ballscrews) can be used inplac e of c ontamination protection de vices . When pla cingan order, b e s ure to spe cify the mo del number.The la byrinth sea l is d es igned to ma intain a c lea rancebetween the sea l and screw-shaft rac ewa y, so that torquedoe s not develop a nd no heat is ge nerated. Howe ver, itseffect in contamination protection is limited.In ballscrews other than the large-lead and super-leadtypes, there is no difference in nut dimensions betweenthose w ith and w ithout a sea l.

Contamination Protection

To ens ure the o ptimum performa nce of the b a llsc rew, thecorrect lubricant and lubrication method for the relevantoperating conditions should be selected.

For the clas sifica tion a nd c harac teristics o f lubrica nts a ndlubrica tion method s, s ee pa ge A-7.

Amount of lubricantInsufficient lubrica nt ca uses poor lubrica tion, w herea s a nexcess ive amo unt of lubrica nt generates heat a nd increase sres ist a nce . It is therefore impo rtant to de termine theoptimum amount of lubricant for the relevant operatingconditions.

GreaseThe a ppropriate a mount of g rea se is normally a pproxima tely1/3 of the vo lume o f the s pa ce w ithin the nut.

OilTab le 1 g ives guidelines for the a mount of oil. P lea se note,however, that the a mount of oil depends on the s troke, typeof oil used , a nd ope rating c onditions (e.g., need to preventhea t g eneration).

As friction is reduced to a very low level in the ballscrew,whe n it is he ld upright , the nut ca n ea sily fall off the sc rew shaft.

P lea se be aw are of this w hen holding the ba llsc rew upright.If the nut is not in place, the balls will also fall off, whichmay da mag e the b a ll circula tion mec hanism including thereturn pipe. S hould the nut be d eta ched from the sc rew

shaft, contac t .

Some ballscrews have exposed ball circulation mechanisms(return pipe, end cap), so be very careful to avoid dents andsimilar impacts.

Handling

When attac hing the ba llsc rew to a ma chine, do not deta chthe nut from the sc rew s haft. If it is nec es sa ry to deta chthe nut, apply a sleeve with a bore approximately 1 mmsma ller tha n the sc rew -shaft threa d minor diamete r so a sto p revent ba lls from fa lling off. Althoug h the threa d of theballscrew is hardened and finished by grinding, forcibledriving o f a pa rt onto the sc rew sha ft or into the nut may

ca use an indenta tion in the ra cew ay. When ass emblingparts on the sc rew sha ft and nut, take care not to a pplyexcess ive force to the s haft and nut.Misa lignment b etw een the s crew-sha ft supported portionand the nut exerts an unnatural force on the ballscrew,resulting in problems suc h a s hea vy rotation. S imila rsymptoms a ppear when the nut and the shaft supportedportion are tilted. These problems a cc elera te wea r onthe ballscrew, which may significantly decrease its servicelife. Therefore, in terms of the mo unting a cc ura cy, pa y closea ttention to misa lignment a nd tilt. Upon co mpletion ofmounting, the b allsc rew must be chec ked by mo ving it overthe entire s troke to ens ure tha t there is no problem w ith itsoperation.In designing your ballscrew system, make sure that no radialloa d or moment is exerted on the ba llsc rew. Rememb erthat a radial loa d or moment may s ignifica ntly dec rea se these rvice life and ca use ma lfunctions.
