The values in thereverse radial and lateral directions are obtainedfrom Table1 below.Equivalent LoadWhen the LM block of models RSR3 to 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 LM block of model RSR12 to 20 receives loads in the radial and lateral directions, or thereverse radial and lateral directions, simultaneously, the equivalent load is obtained from the equationbelow.Table2 Equivalent Factor of Models RSR12 to 20PE X•PR PL Y•PT(When radial and lateral loads are applied)PE : Equivalent load (N): Radial direction: Reverse radial direction: Lateral directionPR : Radial load (N)PL : Reverse radial load (N)PT : Lateral load (N)X, Y : Equivalent factor(see Table2 and Table3)CTC0TPTPLCLC0LFig.3Table1 Basic Load Ratings of Models RSR12 to 20 in All DirectionsDirectionBasic dynamic Basic static loadload rating ratingRadial direction C C0Reverse radialdirectionCL=0.78C C0L=0.70C0Lateral directions CT=0.78C C0T=0.71C0Table3 Equivalent Factor of Models RSR12 to 20(When reverse radial and lateral loads are applied)PE X YEquivalent load in reverseradial direction1 0.99Equivalent load in lateraldirection1.01 1CC0PRCTC0TPE X YEquivalent load in theradial direction1 0.83Equivalent load in lateraldirection1.2 1PTLM GuideIndustrial TechnologiesA1-187
