7007 ACB/P4ADGA Bearing Product Overview & Core Advantages
The 7007 ACB/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. As a universal matchable (SU) bearing supplied in a pre-set pair, it delivers superior performance in handling combined radial and axial loads. Manufactured to the stringent P4A tolerance class, it features an extra light preload (Class A) and is pre-lubricated, making it an ideal, ready-to-install solution for high-speed, high-precision machinery where reliability is critical.
7007 ACB/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Standard bearing series number, indicating a 35mm bore, 62mm OD, and 28mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| B | Designates a 40° contact angle. (Note: Specification data indicates a 25° angle. Please verify the exact design standard for this specific bearing). |
| P4A | Indicates a high-precision tolerance class, with enhanced running accuracy requirements. |
| DGA | Universal Matchable (SU) arrangement. Two bearings are supplied as a matched set for optimal performance. |
7007 ACB/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 25° contact angle and the use of a matched pair (SU) configuration provides high system rigidity, enabling it to handle significant combined loads (radial and axial) simultaneously.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class with extremely tight dimensional tolerances, this bearing ensures smooth, precise operation. The phenolic resin cage is lightweight and robust, contributing to a high limiting speed of 100,500 rpm and stable performance at high velocities.
- Optimized for Matched Arrangements: Being Universal Matchable (SU), the two bearings in the set are designed to be mounted in either a back-to-back (DB) or face-to-face (DF) arrangement, providing flexibility in application design to counteract moment loads or shaft expansion.
- Pre-lubricated & Ready for Use: The bearing comes pre-lubricated, simplifying installation and ensuring immediate, reliable operation from startup.
7007 ACB/P4ADGA Bearing Typical Application Areas
The 7007 ACB/P4ADGA is engineered for high-performance applications, including:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers requiring extreme precision and rigidity.
- Precision Gearboxes: In applications where low noise, high speed, and accurate shaft positioning are critical.
- High-Frequency Spindles: Used in PCB drilling, dental handpieces, and other small tool spindles.
- Robotic Actuators and Joints: Providing accurate and responsive motion control.
- Medical and Laboratory Equipment: Where reliability, cleanliness, and precision are paramount.
