7007 CE/P4ADBG3 Bearing Product Overview & Core Advantages
The 7007 CE/P4ADBG3 is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This duplex back-to-back (DB) arrangement bearing set is preloaded, enabling it to handle combined loads (significant radial and axial loads in both directions) simultaneously. Manufactured to the stringent P4A tolerance class, it offers superior running accuracy and is ideal for high-speed, high-precision machinery where maximum system rigidity and minimal runout are critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Basic bearing series and size designation (35mm bore, 62mm OD). |
| C | Indicates a 15° contact angle, optimized for high-speed performance and moderate axial load capacity. |
| E | Denotes a reinforced (high-capacity) design with a larger ball set and optimized internal geometry. |
| P4A | Specifies the tolerance class, indicating very high precision for dimensional and running accuracy. |
| DB | Signifies a Duplex Back-to-Back matched bearing arrangement. |
| G3 | Indicates the specific preload level applied to the matched set for optimal rigidity. |
7007 CE/P4ADBG3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a wide, rigid support system that effectively resists overturning moments and can accommodate heavy combined loads. The preload (G3) eliminates internal clearance, ensuring precise shaft positioning and enhanced system stiffness.
- Optimized High-Speed Performance: The 15° contact angle and lightweight phenolic resin cage reduce centrifugal forces and friction, enabling stable operation at the high limiting speed of 56,000 rpm.
- Superior Precision: Conforming to the P4A tolerance class, this bearing guarantees minimal runout and exceptional dimensional stability, which is crucial for applications requiring extreme accuracy.
- Enhanced Durability: Manufactured from high-grade chrome steel for both rings and balls, the bearing ensures long service life and reliable performance under demanding conditions.
7007 CE/P4ADBG3 Bearing Typical Application Areas
This bearing is engineered for high-performance applications, including:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers where precision and rigidity are paramount.
- Precision Gearboxes: Especially in robotics and aerospace actuation systems.
- High-Frequency Spindles: Used in PCB drilling and semiconductor manufacturing equipment.
- Medical Equipment: Such as high-speed dental handpieces and imaging device rotors.
