| Code Segment | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| DT | Matched set (Duplex Tandem) arrangement for increased axial load capacity. |
| P | Indicates the bearing is supplied with a preload for enhanced rigidity. |
| P4B | Specifies the P4 (ABEC-7) precision tolerance class. |
7007 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single row angular contact design, combined with a P4 precision class and factory-applied preload, ensures minimal axial and radial runout, providing exceptional rotational accuracy and system stiffness.
- Superior Axial Load Capacity: The 25° contact angle is optimized to handle significant axial loads in one direction efficiently.
- High-Speed Capability: The lightweight and robust phenolic resin cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 20,000 rpm.
- Optimized Internal Geometry: With 16 precision balls of 7.938 mm diameter, the bearing ensures smooth operation and a high dynamic load rating of 3330 lbf.
