v調心球軸承有圓柱孔和圓錐孔兩種結構，保持架的材質有鋼質、合成樹脂等。其特點是外圈滾道呈球面形，具有自動調心性，可以補償不同心度的軸撓度造成的誤差，但其內、外圈相對傾斜度不得超過3°。 vAdjusts the bulbus cordis bearing to have the column hole and the circular cone hole two kind of structures, retainer's material quality has the steel, the synthetic resin and so on. Its characteristic is the addendum circle roller conveyer assumes the ball face shape, has the automatic accent disposition, may compensate the error which the misalignment the axis amount of deflection creates, but among them, the addendum circle relative gradient do not surpass 3°.
