Types Of Deep Groove Ball Bearings

Deep groove ball bearings are one of the most versatile rolling bearings widely used in the machinery industry. Primarily, deep groove ball bearings are designed to withstand radial loads, and they can also stably bear combined radial and axial composite loads. In particular, for mechanical equipment operating at extremely high speeds where thrust bearings cannot be applied, deep groove ball bearings can undertake bidirectional pure axial loads. Featuring maintenance-free operation, low manufacturing cost and excellent universal adaptability, deep groove ball bearings have become the most popular bearing type in various mechanical supporting scenarios.

According to different structural designs and protective configurations, deep groove ball bearings are classified into 11 mainstream models, covering the complete specifications of standard and flanged types:

1. Standard basic deep groove ball bearings (60000 series);

2. Deep groove ball bearings with outer ring retaining groove (60000N series);

3. Single-sided dust cover and outer ring retaining groove type deep groove ball bearings (60000-ZN series);

4. Double-sided dust cover and outer ring retaining groove type deep groove ball bearings (60000-2ZN series);

5. Single-sided dust-proof deep groove ball bearings with one-side dust cover (60000-Z series);

6. Double-sided dust-proof deep groove ball bearings with double-side dust covers (60000-2Z series);

7. Single-sided sealed deep groove ball bearings with single sealing ring (60000-LS, 60000-RZ series);

8. Double-sided sealed deep groove ball bearings with double sealing rings (60000-2LS, 60000-2RZ series);

In addition to structural classification, deep groove ball bearings can be scientifically divided into six categories based on their nominal outer diameter sizes, covering full-size specifications from miniature to extra-large models:

4. Medium and large-sized deep groove ball bearings: The nominal outer diameter ranges from 120mm to 190mm, matching medium-load industrial machinery;

5. Large-sized deep groove ball bearings: The nominal outer diameter ranges from 200mm to 430mm, used for heavy-duty mechanical equipment;

6. Extra-large deep groove ball bearings: The nominal outer diameter is 440mm or above, specially customized for super-large industrial supporting equipment.
