S7024 ACD/P4ADGA Bearing Product Overview & Core Advantages
The S7024 ACD/P4ADGA is a precision double-row angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to simultaneously handle combined radial and axial loads from both directions, this bearing features a compact design that saves space in complex assemblies. Its P4A tolerance class and universal matchable (SU) designation ensure superior running accuracy and simplified mounting in preloaded arrangements. The sealed construction with pre-lubrication offers long-term, maintenance-free operation, making it an ideal solution for high-performance industrial systems.
S7024 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ACD | Angular Contact, Double Row | Enables handling of combined loads from both directions with high rigidity. |
| P4A | High Precision Tolerance Class (equivalent to ABEC 7) | Guarantees exceptional running accuracy and low vibration for precision applications. |
| DGA | Contact Angle of 25° and Universal Matchable (SU) | Optimized for axial load capacity and allows for flexible mounting in preloaded sets. |
S7024 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design and 25° contact angle provide superior stiffness, enabling the bearing to support significant combined radial and axial loads (40,050 lbf dynamic / 52,200 lbf static) with minimal deflection.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards and featuring a lightweight phenolic cage, this bearing ensures smooth operation and is capable of achieving a limiting speed of 10,000 rpm, making it suitable for high-speed applications.
- Sealed & Maintenance-Free Operation: The integrated seals protect against contamination, while the pre-applied grease lubrication operates effectively within a temperature range of -30°C to 110°C, ensuring long service life without the need for re-lubrication.
- Universal Matchability (SU): Bearings can be universally paired in any combination, simplifying the creation of preloaded bearing sets and reducing inventory complexity.
S7024 ACD/P4ADGA Bearing Typical Application Areas
This precision double-row angular contact ball bearing is ideally suited for demanding applications in:
- Machine Tool Spindles
- High-Speed Industrial Pumps & Compressors
- Precision Gearboxes
- Medical and Laboratory Equipment
