Classified by structural characteristics

According to the structure, rolling bearings can be divided into:

Deep groove ball bearings, needle roller bearings, angular contact bearings, self-aligning ball bearings,

Spherical roller bearings, thrust ball bearings, torque spherical roller bearings,

Cylindrical roller bearings, tapered roller bearings, and seated outer spherical bearings.

Bearings are divided into sizes according to their diameter specifications:

1. Miniature bearings-bearings with a nominal diameter of 26mm or less.

2. Small bearings-bearings with a nominal diameter of 28-55mm.

3. Small and medium-sized bearings-bearings with a nominal diameter of 60-115mm.

4. Medium-sized bearings-bearings with a nominal diameter of 120-190mm.

5. Large bearings-bearings with a nominal diameter of 200-430mm.

6. Giant bearings-bearings with a nominal diameter of 440-2000mm.

7. Heavy and extra-large bearings—bearings whose nominal diameter is above 2000mm.
