The values in the reverse radial and lateraldirections are obtained from Table1 below.Equivalent LoadWhen the LM casing of model NSR-TBCreceives loads in the reverse radial and lateraldirections simultaneously, the equivalent load isobtained from the equation below.PEX•PLY•PTPE : Equivalent load (N): Reverse radial direction: Lateral directionPL : Reverse radial load (N)PT : Lateral load (N)X, Y : Equivalent factor (see Table2)CTC0TPTPLFig.1Table1 Basic Load Ratings of Model NSR-TBCin All DirectionsDirectionCLC0LBasic dynamicload ratingBasic staticload ratingRadial direction C C0Reverse radialdirectionCL=0.62C C0L=0.50C0Lateral directions CT=0.56C C0T=0.43C0Table2 Equivalent Factor of Model NSR-TBCCC0PRCTC0TPE X YEquivalent load in reverseradial direction1 1.155Equivalent load in lateraldirection0.866 1Industrial TechnologiesPTA1-252
