This disclosure is directed to a power gripper for use with a robotic tool that includes a housing having formed therein opposed pairs of piston and cylinder arrangements to effect the drive of a corresponding finger carrier slidably supported on each end of the housing for movement between and open and closed position. The respective finger carriers are slidably supported relative to the housing by a pair of diagonally disposed support shafts. Operatively connected to each of the respective finger carriers is a synchronizing shaft in meshing relationship with a pinion for synchronizing the movement of the respective carrier fingers between open and closed position. The arrangement is such that the synchronizing shafts are freely slidable within the housing and independent of the support shaft so as to be free of any sliding friction and/or bearing forces imparted to the support shafts during operation.
