Nettet2. The journal Πbearing kinematic joint A journal Πbearing kinematic joint is schematically represented in fig.1. The journal, p, is usually the rotating element of the joint and it is part of a shaft (i.e. the rotor of a machine). The bearing, c, operates like a constraint as it forces the shaft to rotate around a fixed axis.
