BDP-070 Bearing Demount Press

The Simmons Bearing Demount Press (BDP-070) automatically removes bearings from the axle journals of a railway wheel set. First the height of the jaws is adjusted to the incoming wheel set diameter. The wheel sets then roll into the press from shop rails onto the carriage. The carriage supports the wheel set and moves it precisely to the left and right cylinder beams with a motor-driven rack and pinion. With the wheel set in the correct position, the jaws swing in behind the bearing backing ring where a hydraulic ram pushes a mandrel through the bearing. Once the bearing is removed from the wheel set, the jaws open and the bearing rests on the mandrel for removal. The process is then repeated for the other side before the wheel set is pushed through the machine onto shop rails.

Railway Bearing Demount Press

The press can be supplied for fully automatic or semi-automatic operation, depending on the customer’s production requirement. The removed bearings can be handled in a number of ways. Optional equipment is available to manage the removed bearings either manually or automatically.
