<p><P>PROBLEM TO BE SOLVED: To enhance strength against crack without changing major dimensions of a bearing for a lunger pump. <P>SOLUTION: A bearing for a lunger pump includes an inner ring 2 of a ball bearing formed by interposing a plurality of balls 4 between the inner ring and an outer ring and fitted to an eccentric shaft, wherein an outer peripheral surface of the outer ring 3 is disposed to abut on a plunger of the pump to reciprocate the plunger through the rotation of the eccentric shaft. The wall thickness (t) of the thinnest part of the outer ring 3 in the radial direction is set between 50% and 60% of the diameter (D) of the ball. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
