The values in the reverseradial and lateral directions are obtained fromTable1 below.Equivalent LoadWhen the <strong>LM</strong> block of models RSH7 and 9 receives loads in all four directions simultaneously, theequivalent load is obtained from the equation below.PEPRPLPTPE : Equivalent load (N): Radial direction: Reverse radial direction: Lateral directionPR : Radial load (N)PL : Reverse radial load (N)PT : Lateral load (N)When the <strong>LM</strong> block of model RSH12 receives loads in the radial and lateral directions, or the reverseradial and lateral directions, simultaneously, the equivalent load is obtained from the equation below.Table2 Equivalent Factor of Model RSH12PE X•PR PL Y•PT(when radial and lateral loads are applied)PE : Equivalent load (N)PE X Y: Radial directionEquivalent load1 0.83in the radial direction: Reverse radial directionEquivalent load: Lateral direction1.2 1in lateral directionPR : Radial load (N)PL : Reverse radial load (N)PT : Lateral load (N)X, Y : Equivalent factor(see Table2 and Table3)PTPLFig.1Table1 Basic Load Ratings of Model RSH12 in All DirectionsDirectionBasic dynamic Basic staticload rating load ratingRadial direction C C0Reverse radialdirectionCL=0.78C C0L=0.70C0Lateral directions CT=0.78C C0T=0.71C0PRPTTable3 Equivalent Factor of Model RSH12(when reverse radial and lateral loads are applied)PE X YEquivalent loadin reverse radial direction1 0.99Equivalent load in lateraldirection1.01 1<strong>Industrial</strong> <strong>Technologies</strong>A1-198
