7026 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7026 ACD/P4ADGA is a precision angular contact ball bearing manufactured to P4A tolerance class for exceptional running accuracy. Engineered with a 25° contact angle and Universal Matchable (SU) design, this bearing is optimized to handle combined loads—simultaneously supporting high radial loads and substantial axial loads in one direction. Its Extra light preload (Class A) ensures minimal friction and smooth operation, making it ideal for applications demanding high rigidity and precise rotational performance in high-speed spindle arrangements.
7026 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ACD | 25° contact angle, Universal Matchable (SU) design | Optimized for combined load capacity and simplified mounting in duplex pairs. |
| P4A | High precision tolerance class (superior to ABEC 7) | Ensures high-speed and low-vibration operation for precision applications. |
| DGA | Preloaded (Extra light / Class A), Lubricated | Provides consistent bearing rigidity and is ready for immediate use. |
7026 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 25° contact angle and phenolic cage provides excellent stability, enabling the bearing to handle significant combined radial and axial loads.
- Precision High-Speed Performance: Manufactured to P4A tolerance standards with a lightweight phenolic cage, the bearing achieves a high limiting speed of 11,000 rpm, suitable for demanding high-speed spindle applications.
- Optimized Internal Geometry: Features 21 high-grade chrome steel balls of 22.225 mm diameter, ensuring smooth operation and long service life under heavy loads.
- Universal Matching & Simplified Installation: The Universal Matchable (SU) designation allows any two bearings to be mounted together in back-to-back (DB) or face-to-face (DF) arrangements without selective matching, reducing assembly time and complexity.
7026 ACD/P4ADGA Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery requiring precision and speed, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
