| description | PROBLEM TO BE SOLVED: To provide a bearing hydraulic nut having superior working efficiency during attachment and detachment of a bearing to a shaft. SOLUTION: A nut body 1 includes a hole 4 axially extending from the bottom surface of a recess 1a thereof to the other end surface, and having a large diameter hole portion 4a on the other end side. By inserting a headed bolt 5 into the through-hole 4 from the other end side, the distal end of the bolt 5 is screwed into a plunger 2, and the head thereof is stored in the large diameter hole portion 4a of the through-hole 4. In the state in which the movement of the head of the bolt 5 toward the plunger 2 is restricted halfway in the through-hole 4, the bolt 5 is rotated in a direction to screw into the plunger 2, thereby drawing back the plunger 2 pushed out of the nut body 1 to an initial position. This eliminates the necessity of a tool or the like for drawing back the plunger 2 during the attachment and detachment of the bearing to the shaft, thus improving the working efficiency.
