The invention discloses a precise zirconia ceramic bearing and a processing technology thereof, and belongs to the technical field of bearings. Comprising an outer ring, an inner ring, a retainer and a plurality of rolling bodies which are made of zirconia ceramics, dustproof assemblies are arranged between the two sides of the inner ring and the two sides of the outer ring, and each dustproof assembly comprises a first dustproof cover embedded in the end of the inner circumferential wall of the outer ring and a second dustproof cover embedded in the end of the inner circumferential wall of the outer ring; the second dustproof cover is embedded in the end of the outer circumferential wall of the inner ring and located between the rolling body and the first dustproof cover. According to the bearing, the first dustproof cover and the second dustproof cover are arranged on the outer ring and the inner ring, and dust is not prone to penetrating through dual protection of the first dustproof cover and the second d
