7020 ACD/P4A Bearing Product Overview & Core Advantages
The 7020 ACD/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (radial and axial loads in one direction), this bearing features a 25° contact angle for optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it delivers superior running accuracy and is preloaded for enhanced system stiffness and minimal deflection under operational stresses. Its compact design and high-speed capability (up to 12,000 rpm) make it ideal for demanding precision machinery.
7020 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| AC | Angular Contact design | Optimized for combined radial and axial loads |
| D | High contact angle (25°) | Enhanced axial load carrying capacity |
| P4A | P4 tolerance class with specific internal clearance | Superior running accuracy and preload optimization |
7020 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row angular contact design with P4 precision tolerance ensures minimal runout and high system stiffness. The phenolic resin cage provides excellent dimensional stability and reduced friction at high speeds.
- Superior Load Capacity: With a 25° contact angle and optimized raceway geometry, this bearing efficiently handles combined radial and axial loads. It features a dynamic load rating of 17,842 lbf and static load rating of 18,000 lbf for reliable performance under demanding conditions.
- High-Speed Performance: The lightweight phenolic cage and precision-ground chrome steel components enable stable operation at limiting speeds up to 12,000 rpm. The open design allows for efficient lubrication management in high-speed applications.
- Precision Engineering: Manufactured from high-grade chrome steel with 15.875 mm balls and 22-ball complement, this bearing delivers consistent performance across its operating temperature range of -30° to 110°C.
