所以空载启动后立即切断动力，大型机械不能手动旋转。机械空转，检查有无振动、噪音、旋转部件是否有接触等等，确认无异常后，进入动力运转。
从空载低速开始，动力运转。缓缓的提高至所定条件的额定运转。试运转中检查事项为，否有异常音响、调心球轴承温度的变化、润滑剂的泄漏或变色等等。如果发现异常，应立即中止运转，检查机械，必要时要拆下调心球轴承检查。一般可根据调心球轴承座的外部温度推测。但利用油孔直接丈量调心球轴承外圈的温度更加准确。调心球轴承温度，调心球轴承温度。从运转开始逐渐升高，通常1~2小时后温度稳定。如果调心球轴承装置不良，温度会急剧上升，出现异常高温。其原因诸如润滑剂过多、调心球轴承游隙过小、装置不良、密封装置摩擦过大等。高速旋转的场所，调心球轴承结构、润滑方式的选择错误等也是其原因。
