A single slider crank chain is a four-link mechanism. We know that by fixing, in turn, different links in a kinematic chain, an inversion is obtained and we can obtain as many mechanisms as the links in a kinematic chain. It is thus obvious, that four inversions of a single slider crank chain are possible.

The second category of kinematic chain is the Single Slider Crank Chain. It consists of four kinematic pairs out of which one is a sliding pair and the rest three are turning pairs. If different links of the Single Slider Crank Chain are fixed at different time, four different inversions can be generated.
