The utility model discloses a roll bearing lubricating automatic connection module, which belongs to the technical field of roll bearing lubricating equipment and is used for quick connection and disconnection between a roll lubricating oil supply pipe and a roll bearing block. In technical scheme, the roll bearing lubricating automatic connection module comprises a swing arm, an air duct, a spring, a sleeve, a gland and a quick coupling, wherein the swing arm is L-shaped, the cross bar of the swing arm is fixedly mounted on a working roll roll-bending block by a bolt, the straight bar of the swing arm is a cylinder, the air duct, the spring and the sleeve are mounted in the cylinder, the spring and the sleeve are sleeved on the periphery of the air duct, the lower edge of the sleeve is opposite to the upper end of the spring, the gland is connected at the upper end of the cylinder through the bolt, a round hole is formed at the center of the gland, and the upper end of the air duct passes through the round hole so as to connect the quick coupling. With the air duct floatation technology provided by the utility model, the quick coupling is guaranteed to allow a larger radial deviation when being connected, the defect that an air cylinder structure amplifies the main body error is avoided, structure is simplified greatly, cost of spare parts and maintenance cost are saved, so that the roll bearing lubricating automatic connection module has the advantages of being simple and compact in structure, rational in design and low in price.
