Cylindrical joint

A cylindrical joint is a two-degrees-of-freedom kinematic pair used in mechanisms.

[1] Cylindrical joints constrain two bodies to a single axis while allowing them to rotate about and slide along that axis.

This can be pictured by an unsecured axle mounted on a chassis, as it may freely rotate and translate.

[2] An example of this would be the rotating rods of a table football (foosball).
