Thin walled bearings are widely used in the fields of radar and satellite communication equipment. Radar is an electronic device that uses electromagnetic waves to detect targets, requiring the use of thin walled bearings. Thin walled bearings can be used at the rotational connections of components, effectively reducing rotational resistance. Thin walled ball bearings have a simple structure and are convenient to use. Mainly used to withstand radial loads, but when the radial clearance of the bearing is increased, it has certain performance of angular contact ball bearings and can withstand combined radial and axial loads. Our bearings have the characteristics of low friction coefficient, high speed, and long service life. We have multiple cooperative enterprises to improve efficiency and save costs for users.
