7024 ACD/P4ATBTC Bearing Product Overview & Core Advantages
The 7024 ACD/P4ATBTC is a premium triplex back-to-back angular contact ball bearing set designed for applications demanding exceptional precision and rigidity. This matched arrangement provides superior stiffness and load capacity, making it ideal for handling complex combined loads including radial and significant axial forces in both directions. Manufactured to P4A tolerance class and featuring a moderate preload (Class C), it ensures high running accuracy and stability in demanding operational environments. Its open design allows for optimal lubrication management in high-performance systems.
7024 ACD/P4ATBTC Bearing Model Code Explained, Specifications & Naming Convention
- 7024: Basic designation indicating a 120mm bore, 180mm OD bearing
- ACD: Angular Contact design with a 25° contact angle
- P4A: High precision tolerance class for exceptional running accuracy
- TBT: Triplex Back-to-Back matched arrangement of three bearings
- C: Moderate preload classification for optimal rigidity
7024 ACD/P4ATBTC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The triplex back-to-back configuration creates an exceptionally rigid bearing system capable of withstanding heavy combined radial and axial loads. With a radial dynamic load rating of 53,550 lbf and static load rating of 77,625 lbf, it delivers reliable performance under demanding conditions.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional tolerances (bore/OD: -0.004mm to 0), this bearing ensures minimal runout and vibration. The 25° contact angle provides optimal axial load capacity while maintaining good radial performance.
High-Speed Capability: Featuring a phenolic cage and optimized internal geometry, the bearing achieves a limiting speed of 10,000 rpm, making it suitable for high-speed applications. The open design facilitates efficient lubrication for thermal management at elevated speeds.
Premium Material Construction: Constructed from chrome steel for both rings and balls, the bearing offers excellent wear resistance and durability. The phenolic cage provides strength while reducing weight and friction.
