The attainable speeds for super-precision bearings are primarily dependent on bearing type, design and material, type and magnitude of load as well as lubricant and lubrication method. For the permissible speed, operating temperature is an additional limit.
Super-precision bearing arrangements in high-speed applications require bearings that generate the least amount of friction and frictional heat. Super-precision angular contact ball bearings and cylindrical roller bearings are best suited for these applications. For extremely high speeds, hybrid bearings (bearings with ceramic rolling elements) may be necessary.
When compared to other super-precision bearing types, angular contact ball bearings enable the highest speeds. Diagram 1 compares the relative speed capability of SKF angular contact ball bearings in the different series. For details about the bearing series, refer to the Designation system.
Thrust bearings cannot accommodate speeds as high as radial bearings.
It is a general rule that a certain loss of rigidity must be tolerated to attain higher speeds.
For additional information about attainable speeds, refer to Speeds.
