Ultra-miniature bearing for vibration resistance and damping reduction

The utility model discloses a super miniature bearing for vibration resistance and damping reduction, which is characterized by comprising a bearing body, a bearing inner ring, a retainer and a bearing outer ring are sequentially arranged on the bearing body from inside to outside, a plurality of sealing ring mounting grooves are arranged on the periphery of the bearing outer ring, and sealing rings are arranged in the sealing ring mounting grooves. A shoulder protection sealing ring is arranged at one end of a mounting cavity formed by the bearing outer ring and the bearing inner ring, and one end of the shoulder protection sealing ring extends upwards to be pressed on the bearing outer ring; and a dustproof cover is arranged on the other side of the mounting cavity. Axial damping is reduced while high vibration is restrained, and abrasion of the end face of the bearing and the bearing shell is reduced. 本实用新型公开了一种用于抗振动降阻尼的特微型轴承，其特征在于，包括：轴承本体，在所述轴承本体上由内向外以此设置有轴承内圈、保持架和轴承外圈，所述轴承外圈外周开设有若干密封圈安装槽，在所述密封圈安装槽内设置有密封圈
