7024 ACD/P4AQBCC Bearing Product Overview & Core Advantages
The 7024 ACD/P4AQBCC is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This bearing is supplied as a Quadruplex Back-to-Back (QBC) matched set, providing superior stability and the ability to handle complex combined loads, including significant radial and axial forces in both directions. Manufactured to the stringent P4A tolerance class, it ensures minimal runout and high rotational accuracy. Its moderate preload (Class C) optimizes stiffness while maintaining manageable operating temperatures, making it an ideal choice for high-precision, high-rigidity spindles and machinery.

| 7024 | Basic bearing designation indicating a 120 mm bore, 180 mm OD, and 28 mm width. |
| ACD | Angular Contact design with a 25° contact angle. |
| P4A | Indicates a high-precision tolerance class with very tight dimensional and running accuracy limits. |
| QBCC | Specifies the bearing is part of a Quadruplex Back-to-Back (QBC) matched set with a moderate preload (Class C). |
7024 ACD/P4AQBCC Bearing Structural Features & Performance Benefits
- Exceptional Rigidity and Load Capacity: The Quadruplex Back-to-Back (QBC) arrangement of four bearings creates an extremely rigid support system, capable of withstanding high combined radial and axial loads. This configuration is essential for applications where shaft deflection must be minimized.
- Precision Performance: Manufactured to P4A tolerance class standards, this bearing guarantees high running accuracy and low vibration levels, which is critical for maintaining finish quality in precision machining.
- Optimized High-Speed Capability: The phenolic cage offers low weight and excellent performance at high speeds, contributing to the bearing's capability to operate at a limiting speed of 10,000 rpm. The 25° contact angle provides a balanced performance for both radial and axial loads at high rotational speeds.
- Durable Construction: Made from chrome steel for both rings and balls, the bearing ensures high durability and a long service life under demanding operating conditions.
