7006 CD/P4ATBTA Bearing Product Overview & Core Advantages
The 7006 CD/P4ATBTA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This triplex matched set in a back-to-back (TBT) arrangement provides superior stiffness and stability, enabling it to handle significant combined loads (radial and axial) simultaneously. Manufactured to P4A tolerance class with an extra light preload (Class A), it is engineered for high-speed operation up to 100,500 rpm, making it ideal for ultra-precise spindles and machinery.
7006 CD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD). |
| CD | Contact angle of 15°, optimized for high-speed performance and radial load capacity. |
| P4A | Indicates a high-precision tolerance class (superior to ABEC 7), ensuring minimal runout and vibration. |
| TBT | Triplex Back-to-Back matched set. Three bearings are selectively matched and preloaded as a unit to provide maximum system rigidity and moment load capacity. |
| A | Specifies an Extra Light Preload (Class A), which minimizes friction and heat generation for optimal high-speed operation. |
7006 CD/P4ATBTA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The triplex back-to-back (TBT) arrangement creates a highly rigid bearing system that effectively resists moment loads and shaft deflection, crucial for maintaining precision under heavy cutting forces or high loads.
- Superior Load Capacity: The 15° contact angle and robust construction using chrome steel rings and balls provide a high dynamic load rating of 6908 lbf and static load rating of 5400 lbf, enabling reliable performance under demanding combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight phenolic cage and extra light preload work in concert to reduce centrifugal forces and friction, allowing the bearing to achieve its maximum limiting speed of 100,500 rpm.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls on the bore diameter, outside diameter, and width, ensuring predictable and repeatable performance in the most demanding applications.
7006 CD/P4ATBTA Bearing Typical Application Areas
The 7006 CD/P4ATBTA is specified for high-performance machinery where precision, speed, and rigidity are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Drives: High-frequency motor spindles and servo drives.
- Aerospace & Defense Systems: Gyroscopes, radar equipment, and navigation instruments.
- Medical Equipment: Dental handpieces and high-speed surgical tools.
