S7006 CD/P4A Bearing Product Overview & Core Advantages
The S7006 CD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 15° contact angle, it is optimized to support combined loads, handling significant radial loads and axial loads in one direction simultaneously. Manufactured to the stringent P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed operation and high-reliability scenarios. The bearing comes preloaded and lubricated from the factory, simplifying installation and ensuring immediate, optimal performance.
S7006 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| C | 15° Contact Angle | Optimized for combined radial and axial loads. |
| D | High Load Capacity Design | Enhanced internal geometry for greater load ratings. |
| P4 | Tolerance Class (ABEC-7) | Guarantees ultra-precision for high-speed, low-vibration applications. |
| A | Preload Level | Light preload applied to increase rigidity and minimize axial play. |
S7006 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 15° contact angle and a light preload (A) provides superior system stiffness, critical for applications requiring high positional accuracy and resistance to deflection under load.
- Superior Load Capacity: Engineered with a high-capacity design (D), this bearing offers a dynamic load rating of 3218 lbf and a static load rating of 1800 lbf, enabling it to handle demanding combined loads effectively.
- Optimized High-Speed Performance: The lightweight phenolic resin cage ensures excellent stability and low friction at high rotational speeds, contributing to a high limiting speed of 32,000 rpm.
- Ready-to-Install & Reliable: The bearing is sealed and comes pre-lubricated, protecting it from contamination and providing long-term, maintenance-free operation within its specified temperature range of -30°C to 110°C.
S7006 CD/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance machinery where speed, accuracy, and rigidity are paramount. Key applications include:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Gearboxes
- High-Frequency Motors and Spindles
