7008 CE/DTVQ126 Bearing Product Overview & Core Advantages
The 7008 CE/DTVQ126 is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This duplex tandem (DT) arrangement consists of two preloaded bearings, enabling it to handle significant combined loads (radial and axial) in one direction with maximum stiffness. Manufactured to a P4A tolerance class, it offers superior running accuracy, making it ideal for high-speed, high-precision machinery where uncompromising performance is critical.
7008 CE/DTVQ126 Bearing Model Code Explained, Specifications & Naming Convention
| 7008 | Basic bearing series, indicating a 40 mm bore, 68 mm OD, and 30 mm width. |
| CE | Indicates a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| DT | Signifies a Duplex Tandem preloaded set. Two bearings are mounted in tandem to increase axial load capacity in one direction. |
| VQ126 | A manufacturer-specific code, typically indicating a special group selection for optimal preload and running accuracy within the matched set. |
7008 CE/DTVQ126 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex tandem arrangement and preload create an exceptionally rigid bearing system, effectively resisting deflection under heavy combined loads. This configuration is specifically engineered to handle substantial thrust loads in a single direction.
High-Speed Performance: Featuring a lightweight phenolic resin cage, this bearing is capable of achieving a high limiting speed of 43,000 rpm. The cage ensures stability and reduces centrifugal forces at elevated rotational speeds.
Precision Engineering: Manufactured to P4A tolerance class with a 15° contact angle, this bearing guarantees precise shaft guidance, low noise, and minimal vibration, which is essential for maintaining machining and operational accuracy.
Durability & Reliability: Constructed from chrome steel for both rings and balls, the bearing provides excellent wear resistance and a long operational life under demanding conditions.
7008 CE/DTVQ126 Bearing Typical Application Areas
