ABSTRACT:
Apparatus includes a pilot stud and a ram. The pilot stud is aligned with an end of a shaft. A rotating member is adapted to receive axially inner and outer rolling bearings and be supported by the rolling bearings for rotation with respect to the shaft. The rotating member has a spacer for maintaining a desired separation between the rolling bearings. The rolling bearings and the rotating member are mounted on the pilot stud. The ram has an abutment member that is adapted to engage the outer rolling bearing. The ram is aligned with and moved toward the shaft. Movement of the ram toward the shaft causes the abutment member to move the outer rolling bearing against the spacer and onto the shaft. Also, this movement of the ram toward the shaft causes the spacer to move the inner rolling bearing onto the shaft. So, a single stroke of the ram mounts the rolling bearings and the rotating member onto the shaft. Preferably, the inner and outer rolling bearings each include a cone, a cup, and a tapered roller set adapted to be positioned for rolling between the cone and the cup. The abutment member preferably includes a radially inner abutment for engaging the outer cone and a radially outer abutment for engaging the outer cup. The radially inner and outer abutments have different axial dimensions for maintaining a desired axial spacing between the outer cone and cup.
