7009 CE/DTVQ126 Bearing Product Overview & Core Advantages
The 7009 CE/DTVQ126 is a precision angular contact ball bearing supplied as a matched duplex tandem (DT) set. Engineered for applications demanding high rigidity and exceptional running accuracy under combined loads, this bearing is preloaded and manufactured to P4A tolerance class for superior performance. Its design is optimized to accommodate high axial loads in one direction, making it ideal for high-speed spindles and precision machinery where maximum stiffness and minimal runout are critical.
7009 CE/DTVQ126 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CE | Indicates a 15° contact angle, optimized for high axial load capacity and high-speed operation. |
| DT | Denotes a Duplex Tandem matched set. Two bearings are mounted in tandem to increase axial load capacity in a single direction. |
| VQ126 | Signifies a specific preload class applied to the matched set, ensuring optimal stiffness and rotational accuracy right from installation. |
7009 CE/DTVQ126 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex tandem (DT) arrangement combines two bearings to significantly increase the axial load-carrying capacity in one direction, providing exceptional system rigidity to resist deflection under heavy combined loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class with a 15° contact angle and a lightweight phenolic cage, this bearing ensures smooth operation, minimal vibration, and a high limiting speed of 46,000 rpm.
- Optimized for Preload: The bearings are supplied as a pre-matched and preloaded set (VQ126), eliminating complex calculations and adjustments during installation. This guarantees immediate, high-performance operation with maximum stiffness.
- Durable Construction: Made from chrome steel for both rings and balls, the bearing offers high durability and long service life under demanding conditions.
7009 CE/DTVQ126 Bearing Typical Application Areas
This precision angular contact ball bearing set is ideally suited for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: Applications in PCB drilling, dental handpieces, and small precision motors.
- High-Speed Compressors & Pumps: Where axial load capacity and rigidity are paramount.
