The tool for an insert such as a bearing 2 includes a push collar 20, a push sleeve 30 and an abut sleeve 50. The collar has a first push surface 21 and a second push surface 22, at least one of which is formed with at least two concentric and spaced inserting groove units 24. A distance between at least one of the inserting groove units and a center of the push collar is different from that between any other inserting groove unit and the center of the push collar. The push sleeve has a first push end 31 and a second push end 32. The first push end corresponds to and can be mounted into one of the inserting groove units. The second push end is adapted to push the ring insert. The abut sleeve has a first abut end 51 and a second abut end 52 adapted to abut against the shaft bore unit 3. A means for pushing the push collar along with the push sleeve toward the abut sleeve may include a threaded axle rod 10 and threaded positioning units 40, 60. |
