Rail vertical offset measurement

Rail Vertical Offset

A vertical offset of the rails across the axis will induce a roll moment onto the carriages.  To minimize the effect of this roll moment, tolerances for the vertical offset may be found in the table below. This tolerance describes the attributes of the mounting surface, perpendicular to the rail axis.

The maximum S1 allowed can be calculated by obtaining (S1/a) from the table below.  Then using the following formula.
S1max = a x (S1/a)
