71822 CD/P4 Bearing Product Overview & Core Advantages
The 71822 CD/P4 is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, this bearing is optimized to handle significant combined loads, accommodating both radial and axial forces in one direction. Its compact design, featuring a 16mm width, makes it ideal for space-constrained, high-speed spindles and precision machinery where high rigidity and minimal runout are critical. The phenolic cage and preload availability further enhance its performance in demanding operational environments.
71822 CD/P4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a specific contact angle (15°) and internal design optimized for high rigidity and precise load distribution. |
| P4 | Denotes a high-precision tolerance class equivalent to ABEC-7, ensuring extremely tight dimensional and running accuracy. |
71822 CD/P4 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 15° contact angle and P4 precision grading provide superior stiffness and minimal axial/radial deflection, which is essential for maintaining accuracy under load in machine tool spindles.
- Optimized Load Capacity: Engineered to support high combined radial and axial loads simultaneously. With a dynamic load rating of 7178 lbf and a static load rating of 9112 lbf, it offers reliable performance in rigorous applications.
- High-Speed Capability: The lightweight phenolic resin cage ensures stability and reduced centrifugal forces, contributing to a high limiting speed of 13,000 rpm. This makes it suitable for high-speed applications.
- Preload Availability: The option for preload allows for further reduction in axial and radial play, enhancing system stiffness and rotational accuracy for the most demanding precision tasks.
71822 CD/P4 Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Rotary Tables: Indexing and positioning systems.
- High-Frequency Motors and Spindles: Applications requiring minimal vibration and high rotational accuracy.
- Medical and Laboratory Equipment: Centrifuges and high-speed scanners.
- Robotics: Precision joints and gearboxes.
