7007 CE/HCP4ADGB Bearing Product Overview & Core Advantages
The 7007 CE/HCP4ADGB is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered as a universal matchable (SU) bearing in a light preload (Class B) configuration, it excels at simultaneously handling combined radial and axial loads. Its P4A tolerance class ensures superior running accuracy, while the combination of ceramic balls and a phenolic cage enables outstanding high-speed performance up to 56,000 rpm. This bearing is pre-lubricated for immediate use and operates effectively within a wide temperature range.
7007 CE/HCP4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates the use of ceramic balls (typically silicon nitride), which reduce centrifugal forces, lower operating temperatures, and enable higher speeds. |
| HC | Refers to the phenolic cage material, offering excellent strength-to-weight ratio, reduced friction, and suitability for high-speed operation. |
| P4A | Denotes an ultra-precision tolerance class with extremely tight dimensional and running accuracy specifications, surpassing ABEC 7 standards. |
| DGB | Signifies a Universal Matchable (SU) bearing. Two bearings can be paired in a back-to-back (DB), face-to-face (DF), or tandem (DT) arrangement without the need for selective shimming, providing design flexibility and high rigidity. |
7007 CE/HCP4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 15° contact angle and universal matchable design allow for the creation of preloaded bearing pairs that deliver exceptional stiffness and the ability to withstand significant combined loads (radial and axial).
- Superior High-Speed Performance: The hybrid construction with ceramic balls and a lightweight phenolic cage minimizes centrifugal forces and inertial drag, directly contributing to the high limiting speed of 56,000 rpm.
- Ultra-Precision Operation: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for applications requiring high positional accuracy and smooth rotation.
- Optimized for Matched Sets: As a Universal Matchable (SU) bearing, it simplifies assembly and ensures predictable performance when used in pairs, providing a pre-defined level of preload for immediate operational readiness.
