The values inthe reverse radial and lateral directions areobtained from table 1 below.The basic load ratings of model NRS are equalin all the four directions (radial, reverse radialand lateral directions), and their actual valuesare provided in the specification table for NR/NRS.Equivalent LoadFig.5Table1 Rated Loads in All Directions with Model NRWhen the LM block of model NR receives loads in the reverse radial and lateral directions simultaneously,the equivalent load is obtained from the equation below.Table2 Equivalent Factor of Model NRPEX•PLY•PTPE : Equivalent load (N): Reverse radial direction: Lateral directionPL : Reverse radial load (N)PT : Lateral load (N)X, Y : Equivalent factor (see Table2)DirectionRadialdirectionReverseradial directionLateraldirectionsBasic dynamicload ratingBasic static loadratingWhen the LM block of model NRS receives loads in the reverse radial and lateral directions simultaneously,the equivalent load is obtained from the equation below.CTC0TPTPLCLC0LCCL=0.78CCT=0.48CCC0PRC0CTC0TPTC0L=0.71C0C0T=0.45C0PE X YEquivalent load inreverse radial directionEquivalent load inlateral direction1 20.5 1Industrial TechnologiesPEPRPLPTPE : Equivalent load (N): Radial direction: Reverse radial direction: Lateral directionPR : Radial load (N)PL : Reverse radial load (N)PT : Lateral load (N)A1-174
