7024 ACE/P4A Bearing Product Overview & Core Advantages
The 7024 ACE/P4A is a single row angular contact ball bearing designed for applications demanding high precision and superior running accuracy. Engineered to a P4 (ABEC-7) tolerance class, it is optimized to accommodate combined loads, primarily thrust loads in one direction, while also supporting significant radial loads. Its key advantages include the availability of preload for enhanced system rigidity and a high limiting speed of 13,000 rpm, making it an ideal choice for high-performance, high-speed machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7024 | Basic bearing designation indicating a 120 mm bore, 180 mm OD, and 28 mm width. |
| ACE | Designates a 25° contact angle and specific internal design optimized for high-speed operation. |
| P4A | Indicates the tolerance class P4 (ABEC-7), signifying very high dimensional and running accuracy. |
7024 ACE/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4 tolerance standards, this bearing ensures minimal runout and vibration. The availability of preload further increases system stiffness, critical for maintaining accuracy under load.
- Optimized for High Speeds: The 25° contact angle and lightweight phenolic resin cage work in tandem to reduce centrifugal forces and friction, enabling a high limiting speed of 13,000 rpm.
- Superior Load Capacity: The robust construction using chrome steel for rings and balls provides high dynamic (12,150 lbf) and static (11,700 lbf) load ratings, reliably handling combined radial and one-direction axial loads.
- Temperature Stability: The phenolic cage and standard lubrication offer stable performance across a wide operating temperature range from -30°C to 110°C.
7024 ACE/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-speed and high-precision applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Turbochargers
- High-Performance Pumps and Compressors
