7024 ACE/P4ADGA Bearing Product Overview & Core Advantages
The 7024 ACE/P4ADGA is a precision angular contact ball bearing engineered for applications demanding exceptional accuracy and performance. Operating as a universal matchable (SU) bearing, it is designed to be mounted in pairs to form a duplex arrangement capable of supporting combined loads, including significant radial and axial loads in both directions. Manufactured to the stringent P4A tolerance class, it offers superior running accuracy, high rigidity, and reliable operation at high speeds, making it ideal for high-precision machinery and spindles.
7024 ACE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7024 ACE/P4ADGA provides detailed technical specifications:
- 7024: Basic bearing series and size designation (Bore: 120 mm, OD: 180 mm, Width: 56 mm).
- A: Denotes a 25° contact angle, optimized for carrying high axial loads.
- CE: Indicates the bearing is supplied as a Universal Matchable (SU) set. Two bearings can be mounted in any combination (back-to-back, face-to-face, or tandem) to achieve the required rigidity and load capacity.
- P4A: Specifies the tolerance class, indicating very high precision levels for both dimension and running accuracy.
- DGA: Signifies the bearing is supplied lubricated with a specific grease suitable for the designated operating conditions.
7024 ACE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and duplex mounting capability enable the bearing to handle substantial combined radial and axial loads, providing a highly rigid and stable rotational system.
- Precision Performance: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
- High-Speed Capability: The lightweight and robust phenolic resin cage ensures stable operation and guides the balls effectively, contributing to a high limiting speed of 16,000 rpm.
- Optimized Material & Design: Constructed from chrome steel for both rings and balls, the bearing offers high durability and fatigue resistance. The specified ball diameter and quantity (29) are optimized for the load rating and performance.
7024 ACE/P4ADGA Bearing Typical Application Areas
This high-precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: Applications in PCB drilling, high-frequency motors, and other precision equipment.
- Industrial Pumps and Compressors
- Robotics and Automation: High-accuracy rotary joints and arms.
