Specifications and Design

6002 bearings are single-row, deep-groove ball bearings with the following specifications:

| Specification | Value |
|---|---|---|
| Bore Diameter | 15 mm |
| Outer Diameter | 32 mm |
| Width | 9 mm |
| Rolling Elements | 9 balls, 6.35 mm diameter |
| Static Load Capacity (C0) | 2.5 kN |
| Dynamic Load Capacity (C1) | 6.8 kN |
| Limiting Speed | 12,000 RPM (oil lubrication) |

The deep-groove design allows for axial and radial loads, making them suitable for a wide range of applications.

Selection Criteria

When selecting 6002 bearings, it is important to consider the following factors:

• Load Capacity: Ensure that the bearing can withstand the expected load requirements both radially and axially.
