7024 CB/HCP4A Bearing Product Overview & Core Advantages
The 7024 CB/HCP4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (radial and axial loads simultaneously), this single-row bearing features a 15° contact angle for optimal axial load capacity. Its P4 (ABEC-7) tolerance class ensures ultra-precise running accuracy, making it ideal for high-speed spindles and precision machinery. The combination of a phenolic resin cage and ceramic balls contributes to superior high-speed performance and reduced rotational inertia.
7024 CB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CB | Specific internal design and clearance for matched arrangement applications. |
| HC | Indicates the use of Hybrid Ceramic balls (ceramic balls with steel rings). |
| P4 | Specifies the tolerance class P4 (ABEC-7), denoting very high precision. |
| A | Denotes a 30° contact angle (Note: This bearing uses a 15° angle, "A" may refer to a specific internal design variant). |
7024 CB/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride (Si3N4) ceramic balls significantly reduces friction, heat generation, and wear. This results in a higher limiting speed (17,000 rpm), extended service life, and improved reliability in demanding conditions.
- Precision & Rigidity: Manufactured to P4 tolerance with tight dimensional tolerances on the bore diameter (120 mm) and outside diameter (180 mm), this bearing provides exceptional running accuracy and system stiffness.
- Optimized Cage Design: The phenolic resin cage is lightweight, strong, and exhibits excellent performance at high speeds, contributing to smooth operation and reduced vibration.
- High Load Capacity: With a dynamic load rating of 8482 lbf and a static load rating of 8775 lbf, this bearing is capable of handling significant combined loads.
- Preload Availability: The bearing is supplied with a preload, which eliminates internal clearance, increases system rigidity, and enhances positional accuracy.
