Document Type and Number:
Japanese Patent JP6903761
Kind Code:
B2
Abstract:
The present invention provides a multirow ball bearing and a method of manufacturing the same capable of effectively dispersing a radial load while reducing a frictional force when an inner ring and an outer ring rotate relative to each other. Multiple ball rows (5) are adjacently interposed between an inner ring (3) and an outer ring (4); each of the multiple ball rows (5) includes balls (5a) arranged with prescribed gaps (L) and is arranged to be shifted in a row direction of the ball row (5) relative to a ball row (5) adjacent to the ball row (5), and the balls (5a) in each of the ball rows (5) face spaces (LS) formed by the prescribed gaps (L) in a ball row (5) adjacent to the ball row (5) and are each brought into contact with two of the balls (5a) forming each of the prescribed gaps.
