7010 CD/HCP4A Bearing Product Overview & Core Advantages
The 7010 CD/HCP4A is a high-precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and high-speed performance. As a single-row bearing with a 15° contact angle, it is optimized to support combined loads, handling significant radial loads alongside unidirectional axial loads. Its core advantages stem from its P4 (ABEC-7) tolerance class, ceramic ball material, and phenolic cage, which collectively deliver superior high-speed capability, reduced friction, and excellent dimensional stability. This bearing is preloaded, ensuring high system rigidity and precise rotational accuracy from the outset, making it an ideal choice for high-reliability, precision machinery.
7010 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 7010 | Standard bore diameter (50 mm) and dimension series. |
| CD | Indicates a specific contact angle (15°) and internal design optimized for high rigidity and precise operation. |
| HC | Signifies the use of Hybrid Ceramic balls, offering benefits like reduced weight, lower thermal expansion, and enhanced high-speed performance. |
| P4 | Denotes the tolerance class (ABEC-7), ensuring extremely tight dimensional and running accuracy for precision applications. |
| A | Indicates that the bearing is supplied with a specific preload for immediate high rigidity and minimal runout. |
7010 CD/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The 15° contact angle and factory-applied preload work in concert to deliver high system stiffness and exceptional rotational accuracy, critical for minimizing deflection under load.
- Superior High-Speed Performance: The combination of a lightweight phenolic resin cage and hybrid ceramic balls (Si3N4) significantly reduces centrifugal forces and friction, enabling a high limiting speed of 32,000 rpm. The ceramic balls also provide superior resistance to wear and thermal stress.
- Optimized Load Capacity: Engineered to handle combined loads effectively, with a dynamic load rating of 6660 lbf and a static load rating of 5400 lbf. The angular contact design efficiently supports substantial radial and unidirectional axial loads.
- Pre-Lubricated for Immediate Operation: The bearing is supplied lubricated, ensuring optimal performance from initial startup and simplifying the installation process.
