7010 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7010 ACD/P4ADGB is a precision angular contact ball bearing designed for high-performance applications. Engineered to a P4A tolerance class, it offers exceptional running accuracy and dimensional stability. Its key advantage lies in its ability to handle combined loads—simultaneously supporting significant radial and axial loads. The Universal Matchable (SU) design allows two bearings to be paired in a universal arrangement, providing superior rigidity and operational precision. Pre-loaded with a Light / Class B preload, it is ideal for high-speed spindles and other demanding machinery requiring minimal runout and high reliability.
7010 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| D | Specifies a light preload (Class B) for enhanced stiffness. |
| P4A | Indicates a high-precision tolerance class for superior running accuracy. |
| DGB | Denotes a Universal Matchable (SU) bearing, supplied as a set of two for universal pairing. |
7010 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row angular contact design and phenolic cage provide exceptional structural integrity, enabling the bearing to sustain high combined radial and axial loads (Dynamic: 10395 lbf, Static: 10462 lbf).
- Optimized for High-Speed Operation: The lightweight phenolic cage and 25° contact angle contribute to stable performance at high rotational speeds, with a limiting speed of 46,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring smooth operation and minimal vibration in precision applications.
- Pre-Lubricated & Ready for Use: The bearing comes lubricated from the factory, facilitating immediate installation and initial operation within its specified temperature range of -30°C to 110°C.
