7006 ACD/HCP4ADBB Bearing Product Overview & Core Advantages
The 7006 ACD/HCP4ADBB is a precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement is preloaded to Light / Class B specifications, ensuring optimal stiffness and minimal axial/radial runout. Its construction, featuring a phenolic cage and ceramic balls, is engineered for high-speed operation and superior performance under combined radial and axial loads. This bearing is an ideal solution for high-precision, high-reliability machinery where uncompromising accuracy is paramount.
7006 ACD/HCP4ADBB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD). |
| AC | Angular Contact design with a 25° contact angle. |
| D | Duplex (two bearings in a set). |
| HC | Hybrid Ceramic, indicating ceramic balls for reduced friction and heat generation. |
| P4A | High-Precision Tolerance Class, exceeding ABEC 7/ISO P4 standards for exceptional running accuracy. |
| DB | Back-to-Back mounting arrangement, providing high moment rigidity. |
| B | Light Preload grade. |
7006 ACD/HCP4ADBB Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The duplex back-to-back (DB) arrangement with a controlled light preload creates a highly rigid bearing system that effectively resists moment loads and maintains precise shaft positioning, which is critical for high-precision applications.
Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-density ceramic balls (Hybrid Ceramic) significantly reduces centrifugal forces, enabling stable operation at the high limiting speed of 72,500 rpm. This design minimizes friction and heat buildup.
Excellent Load Capacity: With a 25° contact angle, this bearing is optimized to handle significant combined loads (radial and axial acting simultaneously), making it suitable for applications with complex loading conditions.
Extended Service Life: The use of ceramic balls is not only beneficial for speed but also enhances durability, as ceramic is harder and more resistant to wear and degradation than standard steel.
