The right ascension bearings and declination bearings belong to 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 is very difficult.
BRS RIGIA specialized in customized slewing ring bearings, we can produce according to drawing or samples, design service also available. We devoted to supply customers with the most suitable and cost-effective bearing, not the most expensive bearings.
Sometime the telescope bearings will be used in extreme environment like the Antarctic, so slewing bearings for astronomical telescope need to be produced with special material and processing method, in order to withstand extremely low temperatures.
Three row roller slewing ring bearings are often applied on the radio telescope antenna.
