This kind of bearing outerringraceway is spherical shape, so the self-aligning good performance, to compensate concentricity error.
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。
2
The symmetrical barrel rollers position themselves freely on the concave outerringraceway, which compensates for any shaft misalignment or flexing.
对称每桶辊位置上自由凹外圈滚道，使用户在任何轴偏心或展示。
3
Geometric accuracy and semblance quality were required seriously during grinding outerringraceway and rib of bearing synchronistically, common corindon grinding wheel was not very effective.
