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.
