Abstract
In an angular ball bearing, an outer ring is provided with a plurality of oil holes. The circumferential phases of the plurality of oil holes are θ≥45°, when the angular rolling bearing is viewed in the axial direction during rotation of the bearing, when the center of a ball passes through the center line of one oil hole, the ball closest to the remaining oil hole is located at a position which intersects with the center line of the other oil hole, and when an angle formed by a straight line passing through the center of the ball closest to the oil hole and perpendicular to the radial direction of the angular ball bearing, and a tangent at a contact point between the center line of the oil hole and the ball is set as (θ) when the angular rolling bearing is viewed from the axial direction.
