Bearing for rotary press cylinders

An adjustable bearing arrangement for mounting the spindle end of a rotary printing press cylinder, comprising:

• a press frame, an eccentric bushing rotatably mounted in an aperture in the press frame, clamping means for selectively locking said bushing in position in said frame aperture, a cylinder mounting bracket having a substantially axially extending locating pin rotatably received coaxially in said eccentric bushing, and an anti-friction bearing carried by said mounting bracket coaxially with said locating pin for journalling said cylinder spindle, rotation-inhibiting means for locking said locating pin in an operative position including a rotation-inhibiting lever, a substantially vertical groove formed in the end of said locating pin for receiving and guiding one end of said rotation-inhibiting lever, a knuckle joint disposed parallel to said locating pin, the other end of said lever being pivotally mounted on said press frame around said knuckle joint, said anti-friction bearing including an outer race disposed in an enclosed bearing support ring having a coaxially extending, generally round support pin formed with two substantially vertical and flat outer faces, said cylinder mounting bracket having a bearing support member for receiving said support pin and formed with an open radial slot on one side thereof aligned with said vertical groove in said locating pin and dimensioned to receive said flat outer faces of said support pin therebetween, and said support pin being rotatable within said support member so that said flat outer faces are out of registry with said slot and said support pin is retained in said support member.
