Each bearing will have a resultant normal loadas well as a side load. The orientation of the appliedload with respect to the bearing system is the importantfeature to consider. This means that these equationscan still be used even if the orientation of the translationis not horizontal, as long as the load to bearingrelationship is preserved.Vertical Translation with Vertical Load:when the loadis applied in the direction of travel (thrust), then thefollowing equations should be used to calculate theloads on each bearing block. This type of configurationis generally found in vertical applications. Theorientation of the applied load with respect to the bearingsystem is the important feature to consider. This meansthat these equations can still be used even if theorientation of the translation is not vertical, as long asthe load to bearing relationship is preserved.F2=+L–––4L–––2d4–––d2F1=+d3–––d1()d4–––d2F3=d4–––d2L–––4L–––2d3–––d1d4–––d2F4= + +( )F2S= F4S =d3–––d1( )F1S= F3S =+L–––4d3–––d1( )L–––2F3= F4 =L–––2d4–––d2( )F1= F2 =L–––2d4–––d2( )F1= F3 =L–––2d3–––d1( )F2= F4 =L–––2d3–––d1( )F1S= F3S =L–––2d4–––d2( )F2S= F4S =L–––2d4–––d2( )(7)(8)(9)––––––––
