The ball bearing is respectively sleeved with the clamp springs in the two ring grooves, and the outer edge surfaces of the two clamp springs are respectively contacted with the two ends of the two half outer ring inner walls after being combined.

The ball bearing is provided with joints on the two clamp springs respectively.

The ball bearing, trapezoidal half draw-in groove and trapezoidal snap ring between be interference fit.

Since the technical scheme is used, the utility model discloses following beneficial effect has:

the ball bearing of the utility model, through placing the ball in the ball socket arranged on the outer wall of the inner ring, and arranging the outer ring into a structure formed by combining two halves of the outer ring, the distance between the outer ring and the inner ring is shortened as much as possible, and the purpose of preventing the bearing oil smeared on the bearing from being easily thrown out when the bearing oil runs at high speed is realized; the utility model relates to a novel unique, practicality is strong, energy saving and consumption reduction has very big market spreading value.
