Slider constraint

A slider constraint has five degrees of freedom (DOF) that are fixed, and a sliding X axis that is free. To define the slider constraint, you specify the planar face to constrain, and a direction for the sliding (the X axis).

Note:

When you define a slider constraint on geometry, a local coordinate system is created and applied to the underlying nodes. If local coordinate systems already exist at these nodes, the constraint's coordinate system may overwrite them. For example, if you define a constraint on a location where spring elements are defined, the constraint's coordinate system may overwrite the spring element definitions.
