7013 ACE/HCPA9ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Stiffness: The duplex tandem (DT) arrangement with preload provides exceptional resistance to deflection under heavy axial and combined loads, ensuring precise shaft positioning.
- Superior High-Speed Capability: The combination of a lightweight phenolic cage and low-density ceramic balls reduces centrifugal forces, enabling stable operation at the high limiting speed of 31,000 rpm.
- Enhanced Load Capacity: The 25° contact angle and robust construction provide high dynamic and static load ratings (7020 lbf / 6525 lbf), suitable for demanding combined load conditions.
- Precision Engineering: Manufactured to PA9A tolerance class with tight dimensional controls, this bearing guarantees high running accuracy and minimal vibration for sensitive applications.
