Techno Linear Motion Catalog46Technical Information( )Nominal Life ExpectancyThe nominal life expectancy is achieved, orexceeded 90% of the time before the first indicationof fatigue appears.L=Lh=Lh=L[m]nominal life expectancy in metersLh[h]nominal life expectancy in operating hoursC[N]dynamic loadP[N]dynamic equivalent loadpLife expectancy index:ball-bearing linear guides: p = 3roller bearing linear guides: p = 10/3CpP()Dynamic Loading CapacityThe fatigue behavior of the materials determines thedynamic loading capacity. The life expectancy isdependent on:- the load on the linear guide- the travel speed of the linear guide- the statistical contingency of the first defect takingplaceFundamental PrincipleThe specification of a linear guide is based on theloading capacity of the individual element. Theloading capacity is described by:- the dynamic load data C- the static load data C0- the static moments Mx,My,MzThe basis of the dynamic load data, according to DINstandards, is a nominal life expectancy of 100,000 mtravel. For a nominal life expectancy of 50,000 m, theload data is 20% higher than those values supplied inthis catalog.Loading Capacity and Life ExpectancySelecting a Belt SlideFirst, you must determine...Travel DistanceLoadOrientation of LoadCycle TimeMax SpeedMax AccelerationWith this information, you can start to determine which belt slide is suitablefor your application.1666V(2)(3)(1)Cp() 1 x 105mPx833H x nCpPxx
