7022 CE/HCDTVQ126 Bearing Product Overview & Core Advantages
The 7022 CE/HCDTVQ126 is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. This duplex tandem (DT) matched set is preloaded and manufactured to a P4A super-precision tolerance, ensuring high running accuracy and system rigidity. Its core advantages include the ability to handle high combined loads (radial and axial), superior high-speed capabilities facilitated by a phenolic cage and ceramic balls, and reliable operation within a specified temperature range. This bearing is engineered for high reliability in precision machinery.
7022 CE/HCDTVQ126 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7022 | Basic bearing series, indicating a 110 mm bore, 170 mm OD, and 56 mm width. |
| CE | Indicates a 15° contact angle, optimized for high axial load capacity and speed. |
| HC | Signifies the use of Hybrid Ceramic balls (ceramic balls with steel rings). |
| DT | Denotes a Duplex Tandem arrangement. Two bearings are matched and mounted in tandem to increase axial load capacity in one direction. |
| VQ126 | A manufacturer-specific code often related to a special internal design, preload level, and selection for the matched set. |
7022 CE/HCDTVQ126 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, heat generation, and wear. This construction enables higher limiting speeds, extended service life, and improved reliability, especially in high-speed applications.
Duplex Tandem (DT) Matched Set: This preloaded arrangement provides exceptional axial rigidity and minimizes axial play, which is critical for maintaining precision in spindle applications. The tandem setup is designed to handle heavy axial loads in one direction.
Phenolic Cage: The lightweight and robust phenolic resin cage contributes to smooth operation at high speeds, offering excellent strength and guidance for the ceramic balls.
Super-Precision P4A Tolerances: Manufactured to the tightest dimensional and running accuracy standards, ensuring minimal vibration and superior positional accuracy for the entire spindle system.
