7024 ACE/P4ATBTA Bearing Product Overview & Core Advantages
The 7024 ACE/P4ATBTA is a metric system, precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This bearing features an open seal type and is supplied pre-lubricated. Its primary advantage lies in its matched arrangement as a Triplex Back-to-Back (TBT) set, comprising three individual bearings. This configuration provides extremely high rigidity and superior capacity to handle combined loads (radial and axial), making it ideal for high-precision, high-reliability machinery where minimal deflection is critical.
7024 ACE/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7024 ACE/P4ATBTA provides detailed technical specifications through its suffixes:
- 7024: Basic designation indicating a 120 mm bore, 180 mm OD, and 84 mm width.
- A: Denotes a 25° contact angle, optimized for carrying significant axial loads.
- C: Indicates the Extra light preload (Class A), ensuring minimal internal clearance for high running accuracy.
- E: Signifies a high-capacity internal design with optimized ball size and quantity.
- P4A: Specifies a super-precision tolerance class exceeding standard P4, guaranteeing exceptional dimensional and running accuracy.
- TB: Denotes a Back-to-Back paired arrangement.
- TA: Indicates a Triplex set (three bearings) in the TBT configuration.
7024 ACE/P4ATBTA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The Triplex Back-to-Back (TBT) matched arrangement creates a highly rigid bearing system capable of withstanding heavy combined loads and moments. The 25° contact angle further enhances axial load carrying capability.
- Precision Performance: Manufactured to a P4A super-precision tolerance with an extra light preload, this bearing ensures extremely low vibration and high running accuracy for demanding applications.
- Optimized Internal Design: The use of 29 chrome steel balls with a diameter of 14.288 mm and a phenolic cage provides a robust design suitable for high-speed operation up to 16,000 rpm.
- Material & Lubrication: Constructed from high-grade chrome steel for rings and balls, ensuring durability and long service life. The bearing is pre-lubricated for immediate operation within a temperature range of -30°C to 110°C.
7024 ACE/P4ATBTA Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes and High-Frequency Motors.
- Aerospace Positioning Systems and Robotic Arm Joints.
- Medical Imaging Equipment and other advanced precision instruments.
