7010 CD/P4A Bearing Product Overview & Core Advantages
The 7010 CD/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads—primarily thrust loads in one direction along with significant radial loads—this bearing features a 15° contact angle and is supplied with a P4 (ABEC-7) tolerance class for superior running accuracy. Its phenolic resin cage and pre-lubrication contribute to reliable high-speed operation, making it ideal for demanding, precision machinery.
7010 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| C | 15° Contact Angle | Optimized for handling combined radial and axial loads efficiently. |
| D | High Axial Load Capacity | Enhanced design for increased thrust load capability. |
| P4 | P4 (ABEC-7) Tolerance Class | Guarantees ultra-precision and minimal runout for high-accuracy applications. |
| A | Preload Applied | Ensures high rigidity and precise shaft positioning by eliminating internal clearance. |
7010 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The P4 tolerance class and applied preload work in tandem to deliver exceptional system stiffness and minimal deflection under load, which is critical for maintaining accuracy in precision spindles.
- Superior Load Capacity: With a 15° contact angle and optimized internal geometry, this angular contact bearing is engineered to support significant combined loads, offering a dynamic load rating of 6660 lbf and a static load rating of 5400 lbf.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the pre-applied lubrication allows for a high limiting speed of 28,000 rpm, ensuring stable and reliable operation at high velocities.
- Durable Material Construction: Manufactured from chrome steel for both rings and balls, the bearing provides high wear resistance and long service life under demanding operating conditions.
7010 CD/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for applications requiring high speed, rigidity, and accuracy, including:
- Machine Tool Spindles
- High-Frequency Electric Motors
- Precision Grinding Spindles
- High-Speed Pumps and Compressors
