A system for providing a load on a bearing mounted to a shaft includes an attaching member releasably connectable to the shaft and a press mechanism in fluid communication with a source of fluid and configured to provide a compressive load to the bearing. The press mechanism includes a switch having a base and a piston in communication with the fluid such that an increase in a pressure of the fluid results in the piston extending upwardly from the base and a decrease in the pressure of the fluid results in the piston retracting toward the base. The switch includes a lower proximity sensor and a higher proximity sensor. The piston is configured to extend upwardly from the base past the lower proximity sensor and to trip the higher proximity sensor. The switch is configured to control the increase in the pressure in response to the piston tripping the higher proximity sensor.

Systems and methods are provided for a compound bearing assembly including an offset coupler supporting an inner bearing and an outer bearing for distributing a rotational loading of the compound bearing assembly. In some embodiments, at least one of the bearings comprises a bearing cage with a plurality of elongated openings for receiving a respective plurality of balls. The compound bearing assembly is configured to support a drive shaft of a supercharger system of a vehicle or some other rotational system.

The rotational torque inspection method for a bearing device comprises: a press-fitting step (S02); a first bearing preload value calculation step (S03) for calculating a first bearing preload value (P1); a post-press-fit rotational torque measurement step (S05) for measuring a post-press-fit rotational torque (Ta); a crimping step (S06) for crimping the small diameter step part to the inner ring; a post-crimping rotational torque measurement step (S07) for measuring a post-crimping rotational torque (Tb); a second bearing preload value calculation step (S08) for calculating a second bearing preload value (P2); and a determination step (S09) for determining the suitability of the preload depending on whether or not the second bearing preload value (P2) is within a range of a reference value.

The invention relates to a device and a method for mounting a bearing 200 on a roll neck and for removing the bearing from the roll neck of a roll. Known devices of this type have a first and a second piston/cylinder unit. They also have a stop ring 130, fixed in the axial direction A at the end of the roll neck 320 remote from the body, which acts as a stop for the inner piston 110 of the first piston/cylinder unit. In addition, the known devices have a nut 150 which can be screwed onto an external thread of the inner piston to secure the bearing 200 in the axial direction, in particular during a rolling operation. As an alternative to the known prior art, the present invention provides that an annular cylinder 120 serves both as a cylinder for the first piston/cylinder unit and as a cylinder for the second piston/cylinder unit. For its function as a cylinder for the second piston/cylinder unit, said annular cylinder is covered to a certain ex ent on its side remote from the body by an annular cylinder cover 122. The cylinder cover 122 serves, together with an outer flange 142 of an outer piston 140, to axially delimit a removal pressure chamber 2 of the second piston/cylinder unit.

Systems and methods for removing a bearing assembly from a shaft include a steam ring, the steam ring being a ring shaped member. The steam ring has an inner bore sized to circumscribe the shaft. A lip ring extends from a first end face of the steam ring and has an inner diameter length that is greater than an outer diameter length. A steam inlet port extends through a sidewall of the steam ring. A steam outlet port extends through the sidewall of the steam ring at a location spaced apart from the steam inlet port.

A bearing alignment assembly comprises an outer ring. An inner ring assembly is disposed radially inwardly of the outer ring and cooperating therewith to form a roller volume. The inner ring assembly has a forward inner ring and an adjacent aft inner ring cooperating to provide an inner surface of the inner ring assembly. The forward inner ring includes axial grooves extending axially along and circumferentially spaced around a forward portion of the inner circumferential surface of the inner ring assembly. One or more of the axial grooves of the forward inner ring being an alignment axial groove having at least one cross-sectional dimension different than a corresponding cross-sectional dimension of other of the axial grooves of the forward inner ring, the aft inner ring including axial grooves extending axially along and circumferentially spaced around an aft portion of the inner circumferential surface, at least one of the axial grooves of the aft inner ring having the different cross-sectional dimension and positioned on the aft inner ring for alignment with the alignment axial groove. Rolling elements are rollingly disposed in the roller volume for relative rotational motion of the outer ring and the inner ring assembly.
