7020 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7020 ACD/P4ADGB is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. Engineered to simultaneously handle combined radial and axial loads, this bearing features a 25° contact angle and is supplied as a universally matchable (SU) pair, enabling simplified mounting and optimal preload configuration. Its P4A tolerance class ensures ultra-precise running accuracy, making it ideal for high-speed spindles and other demanding machinery where high rigidity and reliable performance are critical.
7020 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle |
| P4A | High precision tolerance class for superior running accuracy |
| DGB | Paired set arrangement: Universal Matchable (SU) bearings supplied as a duplex pair |
7020 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and duplex pairing (SU) create a highly rigid bearing system capable of supporting significant combined loads. The 25° contact angle provides excellent axial load carrying capacity in both directions when properly arranged.
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional controls (bore: -0.004mm to 0, OD: -0.004mm to 0), ensuring minimal runout and vibration for high-speed applications.
- Optimized Internal Geometry: Features 22 chrome steel balls with a diameter of 15.875 mm arranged in a phenolic cage, providing stable operation at limiting speeds up to 16,000 rpm.
- Superior Material Quality: Constructed from chrome steel for both rings and balls, offering high durability and wear resistance in demanding operating conditions.
- Pre-lubricated Design: Factory lubricated for immediate operation, suitable for temperatures from -30°C to 110°C.
7020 ACD/P4ADGB Bearing Typical Application Areas
- Machine Tool Spindles: High-precision milling, grinding, and turning centers requiring exceptional rigidity and accuracy
