Slewing ring bearing is the most widely applied astronomical devices bearing type. It can be found in a telescope, VLT(very large telescope), observatory, radio telescopes, etc.

The slewing rings used on the right ascension and declination of the telescope belong to the light series thin type slewing ring. The precision requirements are particularly high, and there are technical requirements on pre-tightening, stiffness, and friction torque, so design and processing are very difficult.

Sometimes astronomical devices bearing such as the telescope bearings will be used in extreme environments like the Antarctic, so slewing bearings for astronomical telescopes need to be produced with special material and processing methods, in order to withstand extremely low temperatures.
