71916 CD/P4ADGB Bearing Product Overview & Core Advantages
The 71916 CD/P4ADGB is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing delivers superior dimensional stability and running accuracy. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs, providing excellent rigidity and the ability to support combined loads. With a light preload (Class B), it is optimized for high-speed operation while minimizing friction and heat generation, making it ideal for demanding, high-precision machinery.
71916 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | A 15° contact angle and optimized internal design for high-speed performance and radial load capacity. |
| P4A | Indicates a high-precision tolerance class with enhanced dimensional and running accuracy requirements. |
| DGB | Signifies a universal matchable (SU) bearing, designed to be paired in various configurations (back-to-back, face-to-face, or tandem) without selective mounting. |
71916 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 15° contact angle efficiently supports combined radial and axial loads. The universal matching capability allows for paired mounting, significantly increasing system rigidity and moment load capacity.
- High-Speed Performance: The phenolic resin cage offers low weight and excellent sliding properties, contributing to a high limiting speed of 28,000 rpm. The optimized internal geometry reduces friction and heat generation.
- Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls on the bore, outside diameter, and width, ensuring predictable performance and ease of installation in precision assemblies.
- Durability: Constructed from chrome steel for both rings and balls, providing high fatigue resistance and long service life under demanding operating conditions.
