7210 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 7210 ACD/P4ADGC is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing, it can be paired in various configurations to optimize performance. Its 25° contact angle and P4A tolerance class enable it to handle combined loads efficiently, providing high reliability in precision machinery. The phenolic cage contributes to its suitability for high-speed operation, making it an ideal choice for applications where precision, rigidity, and speed are critical.
7210 ACD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle |
| P4A | High precision tolerance class for superior running accuracy |
| DGC | Universal Matchable (SU) designation, allowing flexible bearing arrangements |
7210 ACD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design and moderate preload (Class C) provide high system rigidity, enabling effective handling of combined radial and axial loads. With a dynamic load rating of 15502 lbf and static load rating of 14738 lbf, it offers robust performance under demanding conditions.
High-Speed Performance: The phenolic cage material reduces centrifugal forces and friction, supporting a limiting speed of 46,000 rpm. This makes the bearing suitable for high-speed applications where thermal stability is crucial.
Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration for precision applications.
Universal Matchability: As a Universal Matchable (SU) bearing, it can be paired in back-to-back, face-to-face, or tandem arrangements without additional machining, providing design flexibility and optimized performance.
