7001 CE/HCP4A Bearing Product Overview & Core Advantages
The 7001 CE/HCP4A is a high-precision single-row angular contact ball bearing engineered for applications demanding exceptional accuracy and performance. This metric series bearing features a 15° contact angle and is supplied with a preload, delivering superior running accuracy and high rigidity. Its optimized design, incorporating a phenolic cage and ceramic balls, enables outstanding high-speed capabilities and extended service life, making it ideal for precision machinery and high-reliability systems.
7001 CE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| CE | Hybrid Ceramic (Silicon Nitride) Balls | Reduced friction, higher speed potential, non-conductive, and longer service life under demanding conditions. |
| HC | Phenolic (Resin) Cage | Excellent strength-to-weight ratio, ideal for high-speed operation with reduced centrifugal forces. |
| P4A | ABEC-7 / ISO P4 Tolerance Class with Specific Running Accuracy | Guarantees extremely tight dimensional and running accuracy for applications requiring minimal vibration and high positional precision. |
7001 CE/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Load Capacity: The angular contact design with a 15° contact angle and applied preload provides high system stiffness, effectively supporting combined radial and axial loads in one direction.
- Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-friction ceramic balls significantly reduces centrifugal forces and operating temperature, enabling a high limiting speed of 150,000 rpm.
- Exceptional Precision: Manufactured to P4 (ABEC-7) tolerance with strict bore, outer diameter, and width tolerances, ensuring smooth, quiet operation and precise rotational accuracy.
- Optimized for Performance: The open seal type allows for customized lubrication schemes, while the standard lubrication is suitable for a wide temperature range from -30°C to 110°C.
