The values in thereverse radial and lateral directions are obtainedfrom Table1 below.Equivalent LoadFig.1Table1 Rated Loads in All Directions with Models HRW 12 and 14When the LM block of models HRW 17 to 60 receives loads in the reverse radial and lateral directionssimultaneously, the equivalent load is obtained from the equation below.PEPE : Equivalent load (N): Radial direction: Reverse radial direction: Lateral directionPR : Radial load (N)PL : Reverse radial load (N)PT : Lateral load (N)When the LM block of models HRW 12 and 14 receives loads in the reverse radial and lateral directionssimultaneously, the equivalent load is obtained from the equation below.Table2 Equivalent Factor of Models HRW12 and 14PEPRX•PLPLPTY•PTPE : Equivalent load (N): Reverse radial direction: Lateral directionPL : Reverse radial load (N)PT : Lateral load (N)X, Y : Equivalent factor (see Table2)PTDirectionRadialdirectionReverseradial directionLateraldirectionsPLBasic dynamicload ratingCCL=0.78CCT=0.48CPRBasic static loadratingC0C0L=0.71C0C0T=0.35C0PE X YEquivalent load inreverse radial directionEquivalent loadin lateral direction1 20.5 1PTLM GuideIndustrial TechnologiesA1-179
