The size of the slide selected for a given application
will depend upon the user’s requirements. Load and slide size are
major variables to consider when choosing your UniSlide. This page
gives general guidelines on load handling for horizontal, vertical
and cantilevered loads. Multi-axis systems require additional design
engineering . In calculating the moment created by a cross slide
you must determine the weight of the upper slide assembly. Weights
are listed in the Price List. Be cognizant of deflection of an unsupported
UniSlide base. For long transport in two or more axes, parallel
coupled slide assemblies using our “B” dovetail base cross sections
are recommended. Please see Parallel Coupled UniSlide Assemblies.
Working With Cantilever Loads
The X axis carries the weight of the Y axis,
the Z axis and the attached load. For good stability, the X axis
should be one model larger than the Y axis when the Y axis length
(L) is longer than three times (3x) the width of the X. Example
1: Two Model MB4012BJ-S4 UniSlides would be suitable in an X and
Y configuration. These models are 4" wide and 12" long. Example
2: If considering two MB4015BJ-S4 Unislides for an X and Y configuration,
choose an MB6018BJ-S6 for the X axis instead. This will be more
stable, since the MB6000 model is 6" wide. The MB4015BJ-S4 is only
15" long-not enough to meet the 3x criteria spelled out above.
