Another advantage of the cartridgebearing is the easy serviceability. In most axial bearings, the cup is an integral part of the hub and cannot be replaced.
另一个轴承利用墨盒是最容易的适用性。大多数轴向轴承，杯子是一个集线器组成部分，不能被取代。

If an axial load rated bearing is the best, why are they less reliable than the sealed cartridgebearing?
如果额定轴向载荷轴承是最好的，他们为什么不可靠的轴承密封墨盒比？

If a similar seal existed for the axial cup-and-cone bearing, the longevity would exceed that of the cartridgebearing.
