71801 CD/P4TGA Bearing Product Overview & Core Advantages
The 71801 CD/P4TGA is a single row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to primarily accommodate axial loads in one direction, this bearing is universally matchable (SU), allowing for precise preload configuration when mounted in pairs or sets. Its P4 tolerance class ensures ultra-precise dimensions and running accuracy, making it ideal for demanding, high-speed machinery. The phenolic cage and optimized internal geometry contribute to its superior performance in high-speed and high-rigidity applications.
71801 CD/P4TGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71801 | Basic bearing series designation, indicating a metric, single row angular contact ball bearing with a 12mm bore. |
| CD | Indicates a 15° contact angle and specific internal design optimized for high-speed operation and universal matching. |
| P4 | Specifies the tolerance class, denoting very high precision for dimensions and running accuracy. |
| TGA | Denotes the cage material: a phenolic resin cage, which is lightweight and excellent for high-speed applications. |
71801 CD/P4TGA Bearing Structural Features & Performance Benefits
High Precision & Rigidity: The P4 tolerance class and precision-ground chrome steel components ensure minimal runout and vibration, providing stable and accurate shaft positioning essential for high-rigidity support.
Optimized for High-Speed Operation: The lightweight phenolic cage (TGA) reduces centrifugal forces and friction, enabling a high limiting speed of 140,000 rpm. The 15° contact angle is ideal for applications requiring high rotational speeds with axial loads.
Universal Matchability (SU): This bearing is designed to be universally matchable, allowing for flexible mounting in pairs (back-to-back, face-to-face, or tandem) to accommodate combined loads and achieve specific preload levels without selective assembly.
Superior Load Capacity: Manufactured from high-grade chrome steel, it offers a dynamic load rating of 1010 lbf and a static load rating of 799 lbf, providing reliable performance under demanding conditions.
71801 CD/P4TGA Bearing Typical Application Areas
- Machine Tool Spindles: High-speed machining centers and grinding spindles requiring extreme precision and rigidity.
- Precision Instrumentation: High-resolution encoders, measuring devices, and scientific instruments.
- High-Speed Motors and Drives: Servo motors, spindle drives, and other high-RPM electric motors.
- Aerospace & Defense Systems: Gyroscopes, navigation systems, and other critical control mechanisms.
