    - A kinematic pair consists of two kinematic links which have either completely or successfully constrained motion between them.

    - Based on the nature of relative motion between links they are classified as:

    1) Sliding pairs
    2) Revolute pairs
    3) Rolling pairs
    4) Globuler pairs.

    - Lower and higher pairs are classified according to the nature of contact between links.

    - Forced closed or self closed pairs are classified according to the mechanical arrangement between links.

    - If two links of a pair are not held mechanically while transmitting relative motion between them, then they are called as force closed pairs or unclosed pairs.
