7007 ACDGA/P4A Bearing Product Overview & Core Advantages
The 7007 ACDGA/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing is engineered to handle combined loads with high reliability. Its extra light preload (Class A) ensures smooth operation with minimal friction, making it ideal for high-precision spindles and other critical machinery where high rigidity and dimensional stability are paramount.
7007 ACDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| 7007 | Basic designation: 35mm bore, 62mm OD, 14mm width. |
| AC | Angular Contact design. |
| DGA | Duplex arrangement, ground back faces, 25° contact angle. |
| P4A | High-Precision Tolerance Class, exceeding ABEC 7 standards. |
7007 ACDGA/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The duplex arrangement (DGA) and P4A tolerance class provide superior running accuracy and system stiffness, essential for minimizing deflection under load.
Optimized for High Speeds: The phenolic resin cage offers low weight and excellent performance at the limiting speed of 56,000 rpm, reducing centrifugal forces and friction.
Superior Load Capacity: With a 25° contact angle and robust construction, this bearing effectively supports combined radial and axial loads (Dynamic Load Rating: 3330 lbf, Static Load Rating: 2025 lbf).
Universal Matching Capability (SU): This bearing is universally matchable, allowing for precise preload control when mounted in sets of two or more, simplifying installation and enhancing system performance.
7007 ACDGA/P4A Bearing Typical Application Areas
The 7007 ACDGA/P4A is ideally suited for high-performance applications requiring extreme precision and speed, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Equipment
- Aerospace Control Systems
- Medical and Dental Handpieces
