摘要： The ball rolling surfaces 11 and 12 of the pocket 7 holding the ball 5 are set in the two spherical surfaces which have a radius larger than the one of the ball 5 and the centers of which are deflected at an equal space from the center of the pocket on the pitch circle of the pocket disposing, and on the inside portions from the edge 9a of the width direction of the pocket and the edge 9b of the height direction of the pocket the contact portions 14 and 15 where the rolling surfaces of the balls and the balls which are positioned at the displacing end contact to form the gaps 16 and 17 on the area determined from the contact portions 14 and 15 to the edge side and make the lubricant G entered through the gaps 16 and 17 into the ball rolling surfaces 11 and 12.

摘要： Described is a bearing including an annular inner raceway formed directly on the outer periphery of a rotary shaft, a plurality of bearing balls held between the inner raceway and an outer raceway formed on the outer periphery of an outer ring, a retainer for retaining the balls in position and a tubular housing securely fitted to the outer ring. The bearing may be designed as the double row type by providing a pair of outer rings each having an inner raceway and a pair of outer raceways formed on the rotary shaft. The inner ring may be dispensed with so that the bearing may be simplified in design and improved in load withstand properties.
摘要翻译：描述了一种轴承，其包括直接形成在旋转轴的外周上的环形内滚道，保持在内滚道和形成在外圈的外周上的外滚道之间的多个轴承滚珠，用于保持滚珠在一个位置上，并且一个管状的外壳牢固地装在外圈上。通过提供一对外圈，每个外圈具有内滚道和形成在旋转轴上的一对外滚道，可将轴承设计为双排型。可以省去内圈，使得轴承可以在设计上简化并且耐负荷性能得到改善。
