In such a setting, the load distribution is not uniformand, as a result, an excessive load is applied in localized areas (i.e., both ends) as shown inFig.2. Continued use under such conditions may result in flaking in those areas, consequently shorteningthe service life. In such a case, calculate the actual load by multiplying the moment value byany one of the equivalent-moment factors specified in Table1 to Table9.<strong>LM</strong> railBall displacement lineFig.2 Ball Load when a Moment is AppliedAn equivalent-load equation applicable when a moment acts on an <strong>LM</strong> <strong>Guide</strong> is shown below.P = K•MMoment loadLoad distribution curveRows of balls under a loadP : Equivalent load per <strong>LM</strong> <strong>Guide</strong> (N)K : Equivalent moment factorM : Applied moment (N-mm)Maximum applied load on a ballMaximum ball deflectionMoment loadBalldisplacement lineRows of balls under a loadLoad distribution curve<strong>LM</strong> <strong>Guide</strong><strong>Industrial</strong> <strong>Technologies</strong>A1-51
