an upper oil seal, an upper dust cover, a lower oil seal and a lower dust cover are clamped between the inner ring and the outer diameter surface as well as the inner diameter surface of the outer ring.

The upper oil seal and the lower oil seal have the same structure, and the upper oil seal is formed by wrapping an annular rubber ring outside an upper oil seal ring sheet.

The structure of the upper dust cover is the same as that of the lower dust cover, two spherical elastic clamping heads are formed on the upper dust cover, and the two spherical elastic clamping heads are respectively clamped in the grooves matched with the inner diameter surface of the inner ring, the outer diameter surface of the inner ring and the inner diameter surface of the outer ring.

The inner ring and the outer diameter surface are formed with inner ring steel ball channels, the inner diameter surface of the outer ring is formed with steel ball inner ring channels, and the steel balls are arranged in the inner ring steel ball channels and the steel ball inner ring channels.

The beneficial effects of the utility model reside in that:

the bearing performance of the bearing is better than that of a steel ball bearing, and the optimal value of the rotating speed is inserted between the steel ball bearing and a roller bearing. It is equipped with oil blanket and shield, and waterproof and dust proof performance is good.

Detailed Description

Example (b): as shown in figures 1 to 4, the bearing with moderate rotating speed and good bearing performance comprises an outer ring 2 and an inner ring 1, wherein steel balls 4 are clamped between the inner ring 1 and the outer diameter surface and the lower part of the inner diameter surface of the outer ring, and are arranged on a steel ball retainer 3; the inner ring 1, the outer diameter surface and the upper part of the inner diameter surface of the outer ring clamp a roller 6, and the roller 6 is arranged on a roller retainer 5;

the roller retainer 5 is structurally characterized in that a plurality of plastic upright columns 52 are formed on a plastic ring piece 51, the plurality of plastic upright columns 52 are distributed on the plastic ring piece 51 in an annular array by taking the circle center of the plastic ring piece 51 as the center, and rollers 6 are inserted between two adjacent plastic upright columns 52;

an outer ring step 2a is formed on the inner diameter surface of the outer ring 2, an inner ring step 1a is formed on the outer diameter surface of the inner ring 1, and the lower end surface of the roller 6 is pressed on the outer ring step 2a and the inner ring step 1 a;

an upper oil seal 7, an upper dust cover 8, a lower oil seal 9 and a lower dust cover 10 are clamped between the inner ring 1, the outer diameter surface and the inner diameter surface of the outer ring.

The upper oil seal 7 and the lower oil seal 9 have the same structure, and the upper oil seal 7 is formed by an annular rubber ring 72 coated outside an upper oil seal ring piece 71.
