调心滚子轴承

Self-aligning roller bearings

调心滚子轴承是在有二条滚道的内圈和滚道为球面的外圈之间，组装着鼓形滚子的轴承。

调心滚子轴承具有两列滚子，主要承受径向载荷，同时也能承受任一方向的轴向载荷。

有高的径向载荷能力，特别适用于重载或振动载荷下工作，但不能承受纯轴向载荷。

该类轴承外圈滚道是球面形，故其调心性能良好，能补偿同轴度误差。

An aligning roller bearing is a bearing with a drum roller assembled between an inner ring with two raceways and an outer ring with spherical raceways.

Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. 

It has high radial load capacity, especially suitable for heavy loads or vibration loads, but cannot withstand pure axial loads. 

This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.
