双列滚动轴承
摘要：
一种双列滚动轴承(1)，具有：在内周上具有两个滚道面(6、6)的外侧构件(2)；配置在该外侧构件(2)的内侧且在外周上具有两个滚道面(7、7)的内侧构件(3)；装入外侧构件(2)的滚道面(6、6)与内侧构件(3)的滚道面(7、7)之间的两列滚动体(4、4)；以及保持滚动体(4)的保持器(5)，外侧构件(2)与内侧构件(3)的任一者由一对滚道圈(3a、3b)形成，且两滚道圈(3a、3b)利用固定用螺栓(16)连结，其特征在于，在一对滚道圈(3a、3b)上设有定位孔(13a、13b)，通过将定位构件(14、14’)嵌合插入该定位孔(13a、13b)来抑制一对滚道圈(3a、3b)在径向上偏芯。
摘要（英）：

A double-row rolling bearing (1) characterized in comprising an outer member (2) having two raceway surfaces (6, 6) on the inner periphery, an inner member (3) disposed on the inner side of the outer member (2) and having two raceway surfaces (7, 7) on the outer periphery, two rows of rolling elements (4, 4) mounted between the raceway surfaces (6, 6) of the outer member (2) and the raceway surfaces (7, 7) of the inner member (3), and a holder (5) for holding the rolling elements (4), the outer member (2) or the inner member (3) being formed by a pair of raceway rings (3a, 3b), and both raceway rings (3a, 3b) being fastened together by a securing bolt (16), wherein positioning holes (13a, 13b) are provided in the pair of raceway rings (3a, 3b), and positioning members (14, 14') are fitted into the positioning holes (13a, 13b), whereby misalignment in the radial direction of the pair of raceway rings (3a, 3b) is inhibited.
