A prismatic joint is a one- degree-of-freedom kinematic pair which constrains the motion of two bodies to sliding
Sliding may refer to:
*Sliding (dance), also floating or gliding, a group of footwork-oriented dance techniques
*Slide (baseball), an attempt by a baseball runner to avoid getting tagged out

along a common axis, without rotation
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional ...
; for this reason it is often called a slider (as in the slider-crank linkage) or a sliding pair. They are often utilized in hydraulic and pneumatic cylinders.
A prismatic joint can be formed with a polygonal cross-section to resist rotation. See for example the dovetail joint and linear bearings.
