71916 FE/HCP4ADGA Bearing Product Overview & Core Advantages
The 71916 FE/HCP4ADGA is a super-precision angular contact ball bearing engineered for the most demanding applications. Its universal matchable (SU) design allows for flexible mounting in pairs to support combined loads—simultaneously handling high radial and axial forces. Manufactured to the exacting P4A tolerance class, this bearing delivers exceptional running accuracy, high rigidity, and reliable performance. The use of a phenolic cage and ceramic balls contributes to its superior high-speed capabilities and extended service life, making it an ideal choice for high-precision, high-reliability machinery.
71916 FE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| FE | Precision design with optimized internal geometry. |
| HC | Hybrid Ceramic: Signifies the use of ceramic balls for reduced friction, higher speed, and longer life. |
| P4A | The tolerance class, denoting extremely high precision for bore diameter, outer diameter, and width. |
| DGA | Universal Matchable (SU): The bearing is designed to be mounted in a universal arrangement (face-to-face, back-to-back, or tandem) with another bearing of the same type without the need for selective matching. |
71916 FE/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 18° contact angle provides excellent resistance to combined radial and axial loads. The universal matchable feature enables pairing to create a highly rigid bearing system.
- Superior High-Speed Performance: The combination of a lightweight, robust phenolic cage and low-density, hard ceramic balls (Si3N4) minimizes centrifugal forces and friction, enabling a high limiting speed of 28,000 rpm.
- Extended Service Life and Reliability: Hybrid construction with ceramic balls significantly reduces wear and is less susceptible to lubrication failure. The extra light preload (Class A) ensures precise shaft positioning and smooth operation from startup.
- Precision Engineering: Manufactured to P4A tolerance standards, this bearing guarantees minimal runout and vibration, which is critical for maintaining accuracy in precision equipment.
71916 FE/HCP4ADGA Bearing Typical Application Areas
