Radial spherical plain bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface.

径向球面滑动轴承由一个具有凸球形外表面的内圈和一个具有相应凹球形内表面的外圈组成。

When grinding the bearing ring, the outside diameter of it was taken as locating datum to process the outer raceway with the assistance of electromagnetic centerless clamper.

轴承环磨削过程中，以轴承环外径作为定位基准，在电磁无心夹具上磨削轴承环外滚道。

As a rule, the outside diameter of the outer ring is ground spherically, so the ring can align itself in a suitably designed sheet-steel or cast-iron housing if the beating locations are misaligned.

按照规定，外圈的外径是，所以在轴承错位的时候能够自调以能够配合一个设计合理的钢板或铸铁钢架。
