One end of the fixing bolt extends into the positioning hole of the installation part and simultaneously fixes the sealing member and the installation part.

[0006] In the above-mentioned rolling bearing convenient for installation, a first sliding groove for the ball bearings to slide is opened on the outer bearing ring. A second sliding groove for the ball bearings to slide is opened on the inner bearing ring. A third sliding groove for the ball bearings to slide and that fits with the first sliding groove is opened on the installation part.

[0007] In the above-mentioned rolling bearing convenient for installation, the diameter of the ball bearings is smaller than the width of the installation groove.

[0008] In the above-mentioned rolling bearing convenient for installation, an installation groove for installing the sealing member is opened on the outer bearing ring.

[0009] Compared with the prior art, in this easily installable rolling bearing, an installation groove is provided on the outer ring of the bearing, and the balls can be installed between the outer ring and the inner ring of the bearing from the installation groove, facilitating the installation by the staff.

[0013] The following are specific embodiments of the present utility model in combination with the drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0014] As Figure 1 , Figure 2 shown, this easily installable rolling bearing includes an inner ring 1 and an outer ring 2 of the bearing. A plurality of balls 3 are arranged between the inner ring 1 and the outer ring 2 of the bearing. Cage 4 is arranged at the upper and lower ends of the balls 3. Seals 6 are arranged on both the upper and lower sides between the outer ring 2 and the inner ring 1 of the bearing. The cross-section of the seal 6 is arranged in a Z-shaped structure. A sealing ring 7 that is in contact with one end of the seal 6 is arranged on the outer peripheral wall of the inner ring 1 of the bearing. The sealing ring 7 and the inner ring 1 of the bearing are integrally formed. The seals 6 arranged on the upper and lower sides are fixedly installed on the outer ring 2 of the bearing through fixing bolts 10.
