For dynamic load correctionfactors see polar graphs below.(†)60 Case LinearRace Support Rail Assemblies are available with 60 CaseLinearRace shaft joints for unlimited travel lengths.For part number description and specifications see page 26 and 27.Polar GraphStandardWithoutHolesStandardWithPre-DrilledHolesAssemblyWith Solid60 CaseLinearRaceshaftStandardSingle PieceLength (†)inMaximumSingle PieceLength (†)inLSR LSR-PD – 48 96LSRA – 180SR SR-PD SRA 24 72The actual Dynamic Load Capacity of a Ball Bushingbearing is determined by the orientation of the bearingor direction of the applied load. The load CorrectionFactor K 0 is found by knowing the direction of theapplied load relative to the orientation of the bearingsball tracks and referring to the polar graph. To determinethe actual Dynamic Load Capacity, multiply theproper correction factor by the Dynamic LoadCapacity listed in the product table on the previouspage. When using LSRA Smart Rail* assemblies,the dynamic load capacity for side loaded or pulloff applications must be de-rated by 75% or .25times the Dynamic Load Capacity.SSURPB012SSURPB016SSURPB024K OK0©2003 Danaher Motion.
