7007 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7007 ACD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-lubricated set of two, it is engineered to accommodate combined loads (radial and axial) simultaneously. Its P4A tolerance class and extra light preload (Class A) ensure smooth, high-precision operation, making it ideal for high-speed spindles and other precision machinery where minimal runout and high system rigidity are critical.
7007 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Basic bearing series, indicating a 35mm bore, 62mm OD, and 28mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Signifies a Universal Matchable (SU) bearing. Two such bearings can be paired in a back-to-back (DB) or face-to-face (DF) arrangement. |
| P4A | Indicates a high-precision tolerance class, superior to ABEC-7, ensuring extremely tight dimensional and running accuracy. |
| DGA | Specifies the extra light preload (Class A) applied to the bearing set, reducing vibration and optimizing performance at high speeds. |
7007 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 25° contact angle and the ability to be universally matched in pairs provides superior rigidity and the capacity to handle significant combined radial and axial loads from both directions.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards with an extra light preload, this bearing minimizes friction and heat generation, enabling a high limiting speed of 56,000 rpm. The phenolic cage is lightweight and robust, contributing to smooth operation at high velocities.
- Optimized for Precision Arrangements: The universal matchable (SU) feature allows for simplified mounting of pre-loaded duplex sets without selective assembly, ensuring consistent, high-performance outcomes in machine tool spindles.
- Pre-Lubricated for Immediate Use: The bearing is supplied lubricated, ready for installation, which facilitates quicker assembly and reduces initial setup time.
7007 ACD/P4ADGA Bearing Typical Application Areas
The 7007 ACD/P4ADGA is engineered for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding, and turning centers)
- Precision Grinding Spindles
- High-Frequency Motors
