Abstract: An installation piece for supporting a roller in a roller stand of a roller frame. The installation piece includes a main bore for receiving a journal of the roller, an inlet for a lubricant, an outlet for the lubricant, and a pump device for pumping the lubricant leaving the installation piece through the outlet. The pump device has a housing, an inlet channel, and an outlet channel. The inlet channel communicates with the inlet and the outlet channel communicates with the outlet for the flow of the lubricant. The pump device is driven by the flow of the lubricant in the inlet. The housing of the pump device is equipped with a screw pump and a turbine, which is driven by the pressurized inflowing lubricant, in the inlet channel for driving the screw pump.
