To provide a bearing unit in which radial rigidity is improved, and cost and torque of a bearing is reduced.
Three, first to third single row bearings 6, 8, and 10 are arranged between a shaft body 2 and a housing 4. The second and third single row bearings are arranged on both sides of the first single row bearing. Each single row bearing includes an inner ring 12, an outer ring 14, and a plurality of rolling elements 16. Between the second single row bearing and the first single row bearing, a spacer 18 is interposed in such condition as abutted with the outer rings. Between the first single row bearing and the third single row bearing, a spacer 20 is interposed in such condition as abutting the inner rings. The inner ring of the second single row bearing abuts an outward flange 2f. The inner ring of the third single row bearing is bonded and fixed to the shaft body. The second single row bearing and the first single row bearing are arranged back to back. The first single row bearing and the third single row bearing are arranged face to face.
