調心球軸承有圓柱孔和圓錐孔兩種結構，保持架的材質有鋼板、合成樹脂等。其特點是外圈滾道呈球面形，具有自動調心性，可以補償不同心度和軸撓度造成的誤差，但其內、外圈相對傾斜度不得超過3度。該類軸承適用于承受重載荷與沖擊載荷、精密儀表、低噪音電機、汽車、摩托車、冶金、軋機、礦山、石油、造紙、水泥、榨糖等行業及一般機械。  

    The self-aligning ball bearing has two structures: cylindrical hole and conical hole. The material of the cage is steel plate, synthetic resin and so on. Its characteristic is that the outer ring raceway is spherical and has automatic heart control, and it can compensate the error caused by different degrees of heart and axis deflection, but the relative inclination of inner and outer ring must not exceed 3 degrees. This kind of bearing is suitable for heavy load and impact load, precision instrument, low noise motor, automobile, motorcycle, metallurgy, rolling mill, mine, oil, paper, cement, squeezing sugar and other industries as well as general machinery.
