The general high-speed bearing refers to the bearing with a speed of 60 meters per second.

Among the sliding bearings, hydrostatic bearings, hydrodynamic bearings, gas static bearings, and gas dynamic bearings are all suitable for high-speed rotation, while general rolling bearings are suitable for low-to-medium-speed rotation. If rolling bearings are used for high-speed rotation, special requirements are required. The above bearings are all easily found in the national standard, and their models can be reasonably selected according to factors such as the load used.

If the speed is between 5 and 60 meters per second, it is not considered a high-speed bearing, and the general bearing can basically satisfy as long as it can be lubricated.
