轴承特性：
低摩擦
挡边上优化的滚子设计和挡边表面光洁度可促进润滑剂膜的形成，从而降低摩擦。 这也减少了摩擦产生的热量和法兰磨损。 此外，轴承可以更好地保持预紧并且降低运行时的噪声水平。
使用寿命长
轴承的基本设计轴承和凸度滚道对数滚道形状可优化沿接触面的载荷分布，减少滚子端部的应力峰值，并降低对不对中和轴偏转的灵敏度 具有常规的直线（图 4）。
提高运行可靠性
滚子和滚道接触面的优化表面处理有利于流体动压润滑油膜的形成。
滚子轮廓和尺寸的一致性
集成在圆锥滚子轴承中的滚子制造公差和尺寸精度极为精密以至于它们几乎完全一样。这提供了载荷分布，以降低噪声和振动等级，并且能够实现更精确的预紧。
刚性轴承应用
一个单列圆锥滚子轴承通常需要配合另一个圆锥滚子轴承共同进行调整。 通过施加预载荷，可以实现刚性轴承应用。
峰值温度下降的跑合阶段
圆锥滚子轴承通常有一个跑合期，在此期间，常规设计的圆锥滚子轴承经历大量的摩擦，导致磨损。 该效果被注意为温度峰值。 在轴承准确无误安装和润滑的前提下，使用圆锥滚子轴承可以大幅降低摩擦、磨损以及摩擦热量。
可分离和互换
即带滚子与保持架组件的内圈（内圈组件）可以与外圈分开安装。 此外，可分离部件是可互换的。 这有助于安装、拆卸和维护检查程序。
