S7024 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides a rigid bearing arrangement capable of supporting high combined loads and moments. With a 15° contact angle, it efficiently manages bidirectional axial loads in addition to heavy radial loads.
Precision & High-Speed Performance: Manufactured to P4A tolerance class with a phenolic cage, this bearing ensures smooth operation and low vibration at high speeds, with a limiting speed of 11,000 rpm.
Sealed & Maintenance-Free Operation: The integrated seals (DGA suffix) effectively protect the bearing from contaminants and retain the pre-filled grease, enabling long service life with minimal maintenance.
Universal Matchable (SU): This bearing is "universal matchable," meaning two bearings can be paired in any combination to achieve the desired preload or clearance without selective mounting, simplifying installation and inventory.
S7024 CE/P4ADGA Bearing Typical Application Areas
The S7024 CE/P4ADGA is ideally suited for high-performance applications including:
- Machine Tool Spindles (High-speed milling, grinding, and turning centers)
- Precision Gearboxes
- Industrial Pumps and Compressors
- High-Frequency Motors
- Medical and Laboratory Equipment
