Kinematic pair which constrains bodies to sliding along an axis without rotating
A prismatic joint is a one-
degree-of-freedom
kinematic pair
[1] which
constrains the motion of two bodies to
sliding along a common axis, without
rotation; 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.
[2]
A prismatic joint can be formed with a
polygonal cross-section to resist rotation. Examples of this include the
dovetail joint and
linear bearings.
