Speed

The permissible operating temperature limits the speed at which rolling bearings can be operated, see the section Reference speeds. Bearing types with low friction and correspondingly low heat generation inside the bearing are therefore the most suitable for high-speed operation.
The highest speeds can be achieved with deep groove ball bearings (fig 1) and self-aligning ball bearings (fig 2) when loads are purely radial and with angular contact ball bearings (fig 3) for combined loads. This is particularly true of high-precision angular contact ball bearings or deep groove ball bearings with ceramic rolling elements.
Because of their design, thrust bearings cannot accommodate as high speeds as radial bearings.
