Rolling Bearing Precision Level Selection

Rolling bearing precision level selectionThe precision level of rolling bearings should be selected in accordance with the mechanical accuracy. To improve the rotation accuracy of the machine and reduce vibration and noise, it should not only rely on increasing the bearing tolerance level. It is necessary to pay attention to the manufacturing accuracy, manufacturing quality and assembly quality of the matching parts. The bearing price double raised according to different bearing precision levels,…

Is it possible to repair bearing?

Installation has a great impact on bearing life. It requires good concentricity and sealing to prevent dust, water and particles entering into the bearing. What’s, Proper radial clearance is also essential.When foreign matter entered card steel, cold rolled steel, it will cause 10 or dozens of times impact force. Therefore, standardized cooperation, eliminate card steel phenomenon are the way to avoid early fatigue damage of bearing.If operating temperature exceeds 120 degree, roller an…
