PURPOSE: A water pump with a bearing is provided to enhance assembling performance since a semi-arc shape of two bearings are mounted on a driving shaft. CONSTITUTION: A water pump with a bearing comprises a driving shaft(200), a first bearing, a second bearing, first and second bearing units. The first bearing is mounted on one side of the outer circumferential surface of the driving shaft. The second bearing is mounted on the other side of the outer circumferential surface of the driving shaft. The second bearing has a semi-arc shape and is fastened to the first bearing. The first bearing unit is overlapped in the length direction of the driving shaft. The second bearing unit respectively corresponds to the first bearing units of the first bearing. The second bearing unit has a semi-arc shape and is overlapped in the length direction of the driving shaft. A through hole is formed through the first bearing in the length of the driving shaft. |
