An apparatus and assembly of a modular bearing device for a pair of gripper arms in a mirror-inverted configuration seated on a support plate for the gripping, holding and guiding of bottle-like containers. The gripper arms are movable from a gripping position into an open position and vice versa by means of a rotatably mounted cam control shaft, each gripper arm having a bearing pin for the pivotal supporting the respective gripping arm and a base plate with a receiving opening running through it for the pivotal supporting of the cam control shaft, wherein the bearing pins are fixed to one side of the base plate, and releasably fastening at least one of the gripper arms on the support plate. With the objective of quick and easy dismantling/assembling, the bearing device is characterized in that the first bearing pin or the second bearing pin is designed as a sleeve for receiving the fastening, the through-hole of which aligns with a receiving opening in the base plate in the axial direction of the sleeve.
