71914 ACE/P4ADGB Bearing Product Overview & Core Advantages
The 71914 ACE/P4ADGB is a precision angular contact ball bearing designed for high-performance applications requiring exceptional accuracy and reliability. This universally matchable (SU) bearing is part of a preloaded pair (Light / Class B), enabling it to handle combined radial and axial loads simultaneously. Manufactured to the stringent P4A tolerance class, it offers superior running accuracy and is optimized for high-speed operation up to 31,000 rpm. Its compact design and high rigidity make it an ideal choice for demanding, precision machinery.
71914 ACE/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACE | Specific internal design with a 25° contact angle and optimized internal geometry. |
| P4A | Denotes a high-precision tolerance class with very tight dimensional and running accuracy limits. |
| DGB | Indicates a Universal Matchable (SU) bearing, designed to be mounted in pairs (duplex sets) with a specific preload (Light / Class B) without the need for selective shimming. |
71914 ACE/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 25° contact angle provides excellent resistance to combined loads. When mounted in a universally matched pair, the system delivers high axial and radial stiffness, crucial for applications with minimal deflection requirements.
- Superior High-Speed Performance: The lightweight and robust phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to the high limiting speed of 31,000 rpm. The open design facilitates efficient lubrication and cooling.
- Precision Engineering: Manufactured to P4A tolerance class, this bearing guarantees precise shaft positioning, low vibration, and smooth operation, which is essential for high-accuracy machinery.
- Universal Matchability (SU): This feature allows for simplified installation of preloaded bearing pairs, ensuring optimal performance and reducing assembly time and complexity.
71914 ACE/P4ADGB Bearing Typical Application Areas
This precision bearing is ideally suited for high-speed and high-precision applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
