| 调心球轴承有圆柱孔和圆锥孔两种结构，保持架的材质有钢板、合成树脂等。其特点是外圈滚道呈球面形，具有自动调心性，可以补偿不同心度和轴挠度造成的误差，但其内、外圈相对倾斜度不得超过3度。 |
| With two structures of bore cylindrical or tapered and retainers made of steel sheet or synthetic resins,the bearings are characteristic of their spherically formed outer ring raceways allowing for misalignment within 3°deflection between inner ring and outer ring,so as to compensate concentricity and deflection errors. |
