S7024 ACDGA/P4A Bearing Product Overview & Core Advantages
The S7024 ACDGA/P4A is a high-precision double row angular contact ball bearing engineered for applications demanding exceptional accuracy and rigidity. Designed to simultaneously handle significant combined loads (radial and bidirectional axial loads), its compact design offers a space-saving solution. Manufactured to the stringent P4A tolerance class, this bearing ensures superior running accuracy, low noise, and vibration, making it ideal for high-reliability, high-speed machinery.
S7024 ACDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| S7024 | Basic bearing series and size designation (120mm bore, 180mm OD). |
| AC | Angular Contact design with a 25° contact angle. |
| D | Double row construction for high rigidity and load capacity. |
| GA | Universal Matchable (SU) bearing in a set of 3, pre-set for specific preload conditions. |
| P4A | High-Precision tolerance class, exceeding ABEC 7/ISO P4 standards for enhanced running accuracy. |
S7024 ACDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to support substantial combined radial and axial loads from both directions, ensuring stable operation under demanding conditions.
- Precision & High-Speed Performance: The phenolic resin cage offers excellent strength-to-weight ratio, reduced friction, and is ideal for high-speed applications. Combined with the P4A precision grade and optimized internal geometry, it contributes to a high limiting speed of 10,000 rpm.
- Sealed & Pre-Lubricated for Longevity: As a sealed bearing pre-filled with grease, it is protected from contamination and is effectively maintenance-free for its service life within the specified temperature range of -30°C to 110°C.
- Universal Matching: The GA suffix indicates the bearing is universally matchable, allowing for flexible mounting arrangements (e.g., back-to-back, face-to-face) in sets to achieve precise preload and system rigidity.
S7024 ACDGA/P4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Gearboxes
- High-Frequency Motors and Spindles
- Industrial Pumps and Compressors
- Advanced Robotics and Automation Equipment
