[0002] Precision machine tool spindles, large electric spindles, and precision lead screw systems often use high-speed precision spindle bearings and precision ball screw bearings in pairs. In order to meet these requirements, it is necessary to accurately measure the protrusion of the assembly end face of a single angular contact bearing under a certain preload. The protrusion of the end face is an important parameter of the bearing, which not only affects the rotational accuracy, rigidity, vibration, and noise of the spindle, but also directly affects the life of the bearing.
