7006/VA9D1 Bearing Product Overview & Core Advantages
The 7006/VA9D1 is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Engineered to simultaneously handle combined radial and axial loads, its single-row design with a 25° contact angle provides optimal performance in high-speed scenarios. Manufactured to P4 tolerance class, this bearing ensures minimal runout and superior rotational accuracy. The Universal Matchable (SU) designation allows for precise preloaded pairs, making it an ideal choice for machine tool spindles and other high-reliability equipment where rigidity and precision are paramount.
7006/VA9D1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series designation, indicating a metric angular contact ball bearing with a 30mm bore, 55mm OD, and 13mm width. |
| V | Indicates the bearing is supplied pre-lubricated from the factory. |
| A9 | Specifies a 25° contact angle, optimized for supporting high axial loads. |
| D1 | Denotes manufacturing to ABEC 7 / P4 tolerance class, ensuring extremely tight dimensional and running accuracy. |
7006/VA9D1 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and robust construction of chrome steel rings and balls enable the bearing to effectively support significant combined loads. The high radial dynamic load rating of 3105 lbf ensures long service life under demanding conditions.
- Superior High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, contributing to a high limiting speed of 100,500 rpm. This makes it suitable for very high-speed spindle applications.
- Precision Engineering: Manufactured to P4 tolerance class with extremely tight bore, outside diameter, and width tolerances, this bearing guarantees exceptional running accuracy and low vibration levels.
- Universal Matching (SU): Bearings designated as SU can be universally matched in any combination to form preloaded sets (typically back-to-back or face-to-face), simplifying installation and ensuring optimal system stiffness.
7006/VA9D1 Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Instruments: Measuring devices and optical equipment requiring minimal runout.
- High-Frequency Motors: Spindles for PCB drilling and other high-RPM electric motors.
- Robotics: High-accuracy joints and arm assemblies.
