7007 ACDGC/P4A Bearing Product Overview & Core Advantages
The 7007 ACDGC/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, it delivers superior running precision for high-performance machinery. This bearing is universally matchable, allowing for flexible mounting in preloaded sets to achieve optimal stiffness and minimal runout. Its 25° contact angle is optimized to handle significant combined loads—both radial and axial—making it an ideal choice for high-speed, high-rigidity spindles and precision systems.
7007 ACDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Basic bearing series with 35 mm bore, 62 mm OD, and 14 mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Optimized internal geometry for high-speed operation. |
| GC | Specific internal clearance/preload group (Moderate / Class C). |
| P4A | High precision tolerance class exceeding ABEC 7 standards. |
7007 ACDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and 25° contact angle provide excellent resistance to combined radial and axial loads. The phenolic cage ensures stable operation under high centrifugal forces.
- Superior Precision: Manufactured to P4A tolerance class with tight dimensional control (bore/OD tolerance: -0.004mm to 0), guaranteeing minimal runout and vibration for ultra-precise applications.
- High-Speed Capability: The lightweight phenolic cage and optimized internal design enable a high limiting speed of 56,000 rpm, making it suitable for demanding spindle applications.
- Universal Matching: Designed as a Universal Matchable (SU) bearing, it can be mounted in pre-arranged sets (up to 3 bearings) to achieve specific preload and stiffness characteristics without selective matching.
- Durability: Constructed from chrome steel for rings and balls, ensuring high fatigue life and reliability in continuous operation within a temperature range of -30°C to 110°C.
7007 ACDGC/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning spindles requiring extreme precision and rigidity.
- Precision Robotics: High-accuracy robotic arms and joints.
- High-Frequency Spindles: PCB drilling and routing machines.
- Medical Equipment: Dental handpieces and high-speed medical scanners.
- Aerospace Systems: Gyroscopes and other critical navigation and control systems.
