7006 CE/HCDGAVQ126 Bearing Product Overview & Core Advantages
The 7006 CE/HCDGAVQ126 is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and high-speed capability. Engineered with a 15° contact angle and an Extra Light (Class A) preload, it delivers superior rigidity and minimizes axial and radial runout. Its universal matchable (SU) design allows two bearings to be paired in a back-to-back or face-to-face arrangement to optimize performance for combined loads. Featuring ceramic balls and a phenolic cage, this bearing excels in high-velocity environments where reduced friction, lower operating temperatures, and extended service life are critical.
7006 CE/HCDGAVQ126 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Ceramic Ball Material | Reduced density for lower centrifugal forces, enabling higher limiting speeds, and improved resistance to wear and electrical arcing. |
| HC | High-Capacity / Phenolic Cage | The phenolic resin cage offers excellent strength-to-weight ratio, low friction, and is suitable for high-speed operation. |
| DGAVQ126 | Internal Design & Universal Match (SU) | Denotes specific internal geometry for optimized load distribution and the universal matchable feature, allowing for simplified mounting and precise preload control in pairs. |
7006 CE/HCDGAVQ126 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 15° contact angle and Class A preload provides superior system stiffness, making it ideal for applications where shaft displacement must be minimized. Manufactured to P4A tolerance class, it guarantees extremely tight dimensional and running accuracy.
- Exceptional High-Speed Performance: The use of ceramic balls significantly reduces centrifugal forces and friction, while the lightweight phenolic cage ensures cage stability. This synergy enables the bearing to achieve a remarkable limiting speed of 100,500 rpm.
- Optimized Load Capacity: As an angular contact ball bearing, it is engineered to support combined loads (simultaneous radial and axial loads). The dynamic and static load ratings of 3398 lbf and 2340 lbf, respectively, ensure reliable performance under demanding conditions.
- Universal Matchability: The SU designation means any two 7006 CE/HCDGAVQ126 bearings can be universally matched. This simplifies inventory and assembly, allowing for precise bearing arrangement (back-to-back or face-to-face) to counteract moment loads or specific thermal expansions.
7006 CE/HCDGAVQ126 Bearing Typical Application Areas
This high-performance bearing is specified for advanced machinery where precision, speed, and reliability are non-negotiable. Key application areas include:
- Machine Tool Spindles: High-speed machining centers, grinding spindles, and CNC lathes.
- Precision Instrumentation: Coordinate measuring machines (CMM) and optical scanning equipment.
- High-Speed Motors and Drives: Servo motors, spindle motors, and turbochargers.
- Aerospace and Defense Systems: Gyroscopes, radar systems, and auxiliary power units (APUs).
