Device for mounting bearings onto a shaft
 A device for mounting a bearing onto a shaft includes a tube connected to the shaft and having an open end. Three grooves are defined longitudinally in the tube and communicate with the open end. A pushing member has three wings extending radially outward therefrom and the wings are movably received in the grooves. Each of the wings has a rod slidably and perpendicularly connected thereto so as to contact a surface of the bearing. A hydraulic pushing rod pushes the pushing member toward the shaft so that the bearing is moved on the shaft.
