Improve, the both ends of the surface of described inner ring are extended the bi-side of outer ring respectively again, and the extended distance of each end face of described inner ring effectively reduces bearing wear less than the diameter of rolling element.
Improve, described rolling element, second rolling element, the 3rd rolling element are all ball, improve usability and the life-span of rolling bearing to a certain extent again.
Improve, described rolling physical efficiency is arranged in the retainer rotationally again, and described retainer can be arranged between described outer ring and the inner ring rotationally, can prevent effectively that rolling element from coming off, guiding rolling element rotation lubricate.
Improve, the two ends between described outer ring and the inner ring are respectively arranged with seal ring again, prevent that grease is on fire, avoid often oiling and simple in structure.
Improve, the shaft hole diameter of described inner ring is less than the 0.1-0.2mm of the middle part through-hole aperture of left seat ring again, and the shaft hole diameter of described inner ring has reduced the friction factor of bearing less than the 0.1-0.2mm of right seat ring middle part through-hole aperture.
Compared with prior art, advantage of the present utility model is: described combination ball bearing is the combination ball design of a rolling bearing and biend bearing, can realize reach to radial load; Retainer and seal ring and end face height and through-hole diameter rationally cooperate, and have reduced the friction factor of this combination ball bearing effectively, thereby have improved usability and the life-span of bearing.
