The bearing of a rotary joint is an important component, such as a high-speed rotary joint. The quality of the bearing determines whether the rotary joint used at high speeds can be used for a long time.
Bearings directly affect the performance of high-speed rotating joints. Poor quality bearings have rough surface machining, uneven chamfers, and a clicking sound when the inner ring rotates. This indicates that the curvature ratio of the inner and outer rings of the bearing is not equal, resulting in insufficient concentricity; If there is noise inside the joint bearing, it indicates that there are impurities. When the high-speed rotation time is long, it will get stuck, and the ball will break, causing the bearing to not rotate. When the high-speed rotating joint rotor is too heavy, it will crush the bearing and cause it to not operate normally; Poor quality bearings cannot guarantee concentricity, resulting in excessive clearance between rotating joints and slight oscillation. If not corrected in a timely manner, it will shorten the service life; In addition, the harsh usage environment accelerates the rusting and heating of the bearings, leading to deformation or rupture of the bearings, which cannot be considered as normal operation.
