7024 CD/P4ADBA Bearing Product Overview & Core Advantages
The 7024 CD/P4ADBA is a precision duplex angular contact ball bearing configured in a back-to-back (DB) arrangement. Engineered to the exacting P4A tolerance class, it is designed for applications demanding exceptional rotational accuracy and system rigidity. Its primary advantage lies in its ability to support combined loads—handling significant radial loads alongside thrust loads in both directions simultaneously. The extra light preload (Class A) ensures minimal deflection and smooth, quiet operation at high speeds, making it an ideal choice for high-precision, high-reliability spindles and machinery.
7024 CD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7024 CD/P4ADBA provides detailed technical specifications:
- 7024: Basic bearing series, indicating a 120mm bore, 180mm OD, and 56mm width.
- C: Denotes a 15° contact angle, optimized for high-speed operation and moderate axial load capacity.
- D: Indicates the bearing is part of a duplex pair (two bearings supplied as a set).
- P4A: Specifies the ultra-precision tolerance class, exceeding ABEC 7 standards, for superior running accuracy.
- DB: Defines the Duplex Back-to-Back mounting arrangement, which provides high moment rigidity and stability.
- A: Signifies an Extra Light Preload applied to the matched set, reducing system deflection and vibration.
7024 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The back-to-back duplex arrangement creates a wide, stable support base that effectively resists moment loads and shaft deflection, ensuring exceptional system stiffness.
- Superior Load Capacity: The angular contact design with a 15° contact angle enables the bearing to efficiently carry substantial combined radial and axial loads from both directions.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground components and optimized internal geometry contribute to a high limiting speed of 16,000 rpm.
- Precision Performance: Manufactured to P4A tolerance class with a preload, this bearing guarantees minimal runout, low noise, and consistent performance in the most demanding applications.
- Material & Construction: Made from high-grade chrome steel for both rings and balls, ensuring high durability and long service life under demanding operating conditions.
7024 CD/P4ADBA Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery where precision and rigidity are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Machining Centers
- Industrial Pumps and Compressors
