7024 ACD/P4ADGB Bearing Product Overview & Core Advantages
The 7024 ACD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. As a universally matchable (SU) bearing supplied in a preloaded duplex set, it is engineered to handle combined loads efficiently, accommodating high radial loads and thrust loads in one direction. Its P4A tolerance class ensures superior running accuracy, making it ideal for high-speed, high-precision spindles and other critical machinery where high rigidity and operational reliability are paramount.
7024 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7024 | Basic bearing series, indicating a 120mm bore, 180mm OD. |
| ACD | Angular Contact design with a 25° contact angle and arranged in a Duplex (DB) pair for universal matching. |
| P4A | Indicates a high-precision tolerance class (equivalent to ABEC 7), ensuring minimal runout and vibration. |
| DGB | Signifies a Light preload (Class B) applied to the duplex set, enhancing system rigidity and rotational accuracy. |
7024 ACD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex pair configuration and 25° contact angle provide superior stiffness, enabling the bearing to support significant combined radial and axial loads. With a dynamic load rating of 40050 lbf and a static load rating of 52200 lbf, it offers robust performance under demanding conditions.
High-Speed Performance: The use of a lightweight, durable phenolic cage and optimized internal geometry allows for a high limiting speed of 16,000 rpm, making it suitable for high-speed applications.
Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls on the bore, outside diameter, and width, this bearing ensures minimal vibration and precise rotational motion.
Universal Matchability (SU): The bearings are universally matchable, allowing any two bearings to be paired in a duplex set without selective assembly, simplifying inventory and installation.
