Dimensionsand weights of machines and installationscan be further reduced.RailsThe rails are ground on all faces. Themaximum rail lengths per piece areshown in the table opposite. SKFsupplies the rails in lengths accordingto customer requirements. The distancemeasurement E (see Illustrationpage 11) is manufactured symmetrically,depending on the raillength.Upon request, SKF can also supplyspecial rails to customer drawings.PerformanceFor improved machinery performance,maximum speeds and accelerationsunder loads acting in alldirections are possible. This permitsmore efficient processes and thereduction of cycle times.Rail designationLLMHR 7LLMHR 9 / LLMWR 9LLMHR 12 / LLMWR 12LLMHR 15 / LLMWR 15*For rail length > 1 000 mm, please contact SKF.ReliabilityMore than 90 years of SKF experiencewith rolling bearing geometryguarantee long product life. Maintenanceintervals are extended and theservice life of machines and installationsis increased.ResistanceThe use of stainless steel in combinationwith plastic componentsmakes these guides universallyapplicable. The reliability in applicationengineering is increased andrisks are eliminated.Maximum rail lenght per piece*1 000 mm1 000 mm1 000 mm1 000 mmCarriagesA wide range of 14 different types ofcarriages, each available in threepreload classes and with a choicebetween sealed and open types, permitsoptimum system designs tailoredto the respective requirementprofile.Preload and stiffnessThe determination of an appropriatepreload renders the miniature profilerail guide suitable for widely varyingoperating conditions and changes thestiffness of the overall system.SKF recommends clearance-freesystems (T0) for applications withconstant load and low friction. Forapplications characterised by shockloads, vibration and alternating loadsor torques, it is advisable to select apreloaded system (T1) and a (T2)system should be chosen for hightorques and high stiffness.Preload classCharacteristicsT0ClearanceT1Light clearance up to light preloadT2Preloaded systemfurther preload classes upon request5
