71913 CE/HCP4ADT Bearing Product Overview & Core Advantages
The 71913 CE/HCP4ADT is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Engineered as a duplex tandem (DT) pair, this bearing is preloaded and ready for installation, delivering superior high rigidity and the ability to handle significant combined loads. Featuring a phenolic cage and ceramic balls, it is optimized for high-speed operation and offers an extended service life in precision machinery.
71913 CE/HCP4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71913 | Standard bearing series and size designation. |
| CE | Contact angle of 15°. |
| HC | Hybrid Ceramic: Features ceramic balls for enhanced speed and life. |
| P4A | High precision tolerance class, exceeding ABEC 7/ISO P4. |
| DT | Duplex Tandem arrangement. Two bearings are matched and preloaded to share axial loads in the same direction. |
71913 CE/HCP4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex tandem arrangement and 15° contact angle create a highly rigid system capable of supporting substantial combined radial and axial loads in one direction. This configuration is essential for applications requiring minimal shaft deflection.
Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-density ceramic balls (Hybrid Ceramic) significantly reduces centrifugal forces, enabling a high limiting speed of 31,000 rpm. This makes it ideal for high-speed spindles.
Extended Service Life & Reliability: Ceramic balls are harder, smoother, and lighter than steel, leading to reduced wear, lower operating temperatures, and longer bearing life. The P4A precision tolerance ensures smooth, quiet, and vibration-free operation.
Pre-Lubricated & Ready for Use: The bearing comes pre-lubricated, ensuring immediate and optimal performance upon installation within its specified temperature range.
