7005 CE/HCDTVQ126 Bearing Product Overview & Core Advantages
The 7005 CE/HCDTVQ126 is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. As a duplex tandem (DT) arrangement bearing set, it is preloaded and matched to deliver superior high rigidity and axial load capacity in one direction. Its construction, featuring a phenolic cage and ceramic balls, is optimized for high-speed operation, making it an ideal solution for high-precision, high-reliability machinery where uncompromising accuracy and stiffness are paramount.
7005 CE/HCDTVQ126 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a 15° contact angle and specific internal design optimizations. |
| HC | Signifies the use of Hybrid Ceramic balls (Silicon Nitride). |
| DT | Denotes a Duplex Tandem preloaded and matched set of two bearings. |
| VQ | Specifies a Phenolic (resin) cage for reduced weight and superior high-speed performance. |
| 126 | Internal code related to specific preload and matching criteria. |
7005 CE/HCDTVQ126 Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Load Capacity: The duplex tandem arrangement and built-in preload create an exceptionally stiff bearing system, capable of handling heavy combined loads with a primary focus on unidirectional axial loads.
- Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-density, high-hardness ceramic balls significantly reduces centrifugal forces, enabling a high limiting speed of 56,000 rpm.
- Enhanced Durability & Precision: Manufactured to a P4A tolerance class, this bearing ensures ultra-precise running accuracy. The open seal type allows for customized lubrication schemes to maximize performance in specific operating environments.
- Extended Service Life: Ceramic balls offer excellent wear resistance, lower friction, and are electrically insulating, contributing to longer bearing life and reduced maintenance intervals.
7005 CE/HCDTVQ126 Bearing Typical Application Areas
This bearing is engineered for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Robotics and Automation Arms
- High-Frequency Motors and Spindles
- Medical Equipment (e.g., Dental handpieces, Centrifuges)
