Thus, the relative movement between points in two connected links is considered to result from the kinematic pair that joins them.

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

A kinematic pair is a connection between two bodies that imposes constraints on their relative movement.

A mechanism is modeled as an assembly of rigid links and kinematic pairs.

Reuleaux called the ideal connections between components that form a machine kinematic pairs.

Mathematical models of the connections, or joints, between two links are termed kinematic pairs.

Hartenberg & Denavit presents the definition of a kinematic pair:

Reuleaux believed that machines could be abstracted into chains of elementary links called kinematic pairs.

This one parameter movement identifies this joint as a one degree of freedom kinematic pair.

Similarly, the flat surface of an inclined plane and wedge are examples of the kinematic pair called a sliding joint.

Rigid bodies, or links, connected by kinematic pairs, or joints, are called kinematic chains.

It was Reuleaux who focussed on bodies, called links, and the connections between these bodies called kinematic pairs, or joints.

Constraints on the machine are described by constraints on each kinematic pair, and the sequence of movements of pairs produces a kinematic chain.

Elements of kinematics diagrams include the frame, which is the frame of reference for all the moving components, as well as links (kinematic pairs), and joints.

The engine was connected with a three-speed Transmission (mechanics) and then directly via a torque tube to the rear axle, thus eliminating the need for Kinematic pair.

Franz Reuleaux introduced the kinematic pair as a new approach to the study of machines that provided an advance over the motion of elements consisting of simple machines.

Kinematic pairs model the hinged and sliding joints fundamental to robotics, often called lower pairs and the surface contact joints critical to cams and gearing, called higher pairs.

The bearings that form the fulcrum of a lever and that allow the wheel and axle and pulleys to rotate are examples of a kinematic pair called a hinged joint.

Kinematic pairs, or joints, are considered to provide ideal constraints between two links, such as the constraint of a single point for pure rotation, or the constraint of a line for pure sliding, as well as pure rolling without slipping and point contact with slipping.
