| description | The utility model relates to the field of bearings, and particularly discloses an angular contact ball bearing for an electric tool. The angular contact ball bearing comprises an inner ring, an outer ring, a rolling body and a retainer, and two sealing covers are further arranged between the inner ring and the outer ring; the contact angle of the rolling body is alpha which is equal to 30 +/-2 degrees; the outer edge of the sealing cover makes contact with the outer ring and rotates synchronously with the outer ring, and a gap is reserved between the inner edge of the sealing cover and the inner ring. A sealing groove is formed in the outer edge of the inner ring; a main sealing lip and an oil guide lip are arranged on the inner edge of the sealing cover, and the main sealing lip is arranged in the sealing groove; and the oil guide lip is arranged towards the rolling body and extends to a part of the end surface covering the outer flange of the inner ring in the axial direction.
