There are many classifications and definitions of bearings, one of which is called high-speed bearings. High-speed bearings are generally used inside machinery; some small bearings cannot move tens of thousands of revolutions. In fact, this cannot be regarded as a high-speed bearing, especially a large bearing with hundreds of Turns can be called high-speed bearings, why? Many people will ask, what kind of bearing is a high-speed bearing? Since the high-speed bearing is calculated at the line speed, when the bearing speed reaches 60m/s, it has been regarded as a high-speed bearing. High-speed bearings are generally more accurate than low-speed bearings, and the surface is relatively smooth; low-speed bearings are called rolling bearings, and high-speed bearings are called sliding bearings. Rolling bearings are generally spherical, cylindrical, and conical, and high-speed sliding bearings are generally bearing bushes. 37 years of professional production of high-speed bearings and low-speed bearings, customized according to customer application scenarios, to meet the speed requirements of various scenarios.
