2. The outer ring and the inner ring of the boring tool or the hacksaw blade to be smashed or slid, and the outer ring and inner ring of the bearing should be “giggle” and free from swarf, scratches or only inconspicuous fine marks. If the bearing has the markings blurred, the appearance is dull, the swaying has a gap, the outer ring rotates at the same position, there are scraps or scratches during the slashing, the rust stains on the cage, etc., indicating that the bearing quality is unqualified, do not buy.

3. The end face of the outer ring should be marked with the code name, origin and date of manufacture, and it should be clearly conspicuous.

4. Hold the inner and outer rings separately with both hands so that they move relative to each other in the radial and axial directions. There should be no sense of clearance. Larger bearings can feel the gap, but there should be no metal impact.

5. For qualified ball bearings, it is made of high-quality bearing steel. The inner and outer rings and cages should be bright as a mirror after wiping off the anti-rust oil. The hand should be smooth and delicate when touched.

6. Make a mark on the outer ring. Whenever you stop, the stop position of the mark should be different.

7. The rivet riveting between the cages should be uniform and the rivet heads should be unbiased. Support the inner ring by hand and the outer ring by the other hand. The outer ring should be able to rotate quickly and then gradually stop.
