www.lmotion.ru lmotion-mail@ya.ru Тел.: (495)-921-34-60Load carrying capacityStatic load rating C 0The static load rating C 0 is the loadwhich corresponds to an arithmeticalHertzian Pressure of 4 200 MPabetween raceway and balls. Thispressure produces a permanent deformationof approximately 0,0001of the ball diameter.Static moments “M A , M B , M C ”The permissible static moments correspondto a moment load that producesthe same permanent deformationas in the static load rating C 0 .Load directionSKF miniature profile rail guides aredesigned to accommodate loads in alldirections.Dynamic load rating CThe dynamic load rating C is theconstant load which gives a theoreticalsystem life of 100 000 m of travelwith a certainty of 90 %.Life calculationThe life of a profile rail guide is definedas the total linear distancetravelled before the appearance ofthe first signs of material fatigue onthe raceways or rolling elements.Both in laboratory trials and inpractice it is found that the life ofapparently similar rail guides undercompletely identical operating conditionscan differ. Calculation of therequisite bearing size thereforerequires a clear statistic definition ofthe term bearing life. All referencesto dynamic load rating of profile railguides apply to the basic rating lifeas covered by the ISO definition, inwhich life is understood as that operatingperiod reached or exceeded by90 % of a large group of identicalbearings. The SKF life calculation isbased on 100 000 metres of travel.Other calculation models assumemerely 50 000 metres of travel. Insuch cases, the dynamic load ratingsmust be divided by a factor of 1,26to ensure comparability with the SKFvalues.Where the stroke length and frequencyare constant it is often easierto calculate the basic rating life inhours of operation using the equation:Permissible operatingconditionsPermissible maximum loadDIN 636, Part 2, stipulates that thecalculation of bearing life is valid onlywhen the equivalent dynamic loadingof a profile rail guide does not exceed0,5 C. Any higher loading leads to animbalance of stress distributionwhich can have a negative effect onbearing life. Where such conditionsprevail, the user should turn to SKFfor recommendations and advice onbearing life calculation.Requisite minimum loadIn order to assure slip-free runningof profile rail guides, they must besubjected to a certain minimum load.The general guideline is a minimumvalue of P = 0,001 C. The minimumload is of special importance in profilerail guides which operate at highspeed or with high acceleration. Insuch cases, the inertia forces of theballs as well as the rolling friction inthe lubricant can have an adverse effecton the rolling conditions in theguide and can lead to damaging slipconditions between the balls andraceways.L 10 =12CP3L 10CP= basic rating life, 10 5 m= dynamic load rating, N= equivalent dynamic bearing load, NL 10 h =50 000 000s · n · 6012CPL 10 h = basic rating life, hours of operations = stroke, mmn = frequency of stroke, min -1(number of movements from oneend position to the other end andback again)37
