71916 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 71916 ACD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Operating under a P4A tolerance class, this bearing is engineered to handle combined loads efficiently, with its 25° contact angle optimizing performance for high axial load capacity. Its universal matchable (SU) design allows for flexible mounting in pairs to support bidirectional axial loads, making it an ideal, compact solution for high-speed, high-reliability machinery where precision is paramount.
71916 ACD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle. |
| P4A | Indicates a high-precision tolerance class with enhanced running accuracy. |
| DGC | Signifies a phenolic cage material, contributing to lower friction and suitability for high-speed operation. |
71916 ACD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and moderate preload (Class C) provide superior stiffness, enabling the bearing to withstand significant combined radial and axial loads.
- High-Speed Performance: The lightweight phenolic cage (DGC) reduces centrifugal forces, while the optimized internal geometry supports a high limiting speed of 17,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls on the bore diameter, outside diameter, and width, ensuring consistent performance and smooth operation in precision assemblies.
- Universal Matchability (SU): Bearings are supplied lubricated and are universally matchable, allowing for simplified pairing in duplex sets (back-to-back or face-to-face) without selective mounting, which saves time and reduces complexity.
71916 ACD/P4ADGC Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Medical and Dental Equipment
- Aerospace Control Systems
