S7002 ACD/HCP4A Bearing Product Overview & Core Advantages
The S7002 ACD/HCP4A is a high-precision, single-row angular contact ball bearing engineered for applications demanding exceptional speed and rigidity. Its defining feature is the ability to support combined loads—significant radial and one-directional axial loads simultaneously. Manufactured to a P4 (ABEC-7) tolerance class and featuring a ceramic ball and phenolic cage construction, this bearing is optimized for high-speed operation and superior performance in demanding environments. The sealed and pre-lubricated design ensures long-term reliability and minimal maintenance.
S7002 ACD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S7002 | Basic bearing series and size designation (15mm bore, 32mm OD). | Defines the core bearing dimensions. |
| ACD | Angular Contact Design with a 25° contact angle and preload. | Enables high rigidity and precise shaft positioning under combined loads. |
| HC | Hybrid Ceramic: Signifies the use of ceramic balls. | Reduces weight and centrifugal force, enhancing high-speed performance and longevity. |
| P4A | Indicates a P4 (ABEC-7) tolerance class. | Guarantees extremely tight dimensional and running accuracy for precision applications. |
| Sealed / Lubricated | Integrated seals and factory-applied lubricant. | Provides contamination protection and promotes a maintenance-free service life. |
S7002 ACD/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Preload: The angular contact design with an applied preload significantly increases system stiffness, minimizing deflection under load for improved operational accuracy.
- Superior High-Speed Capability: The combination of a lightweight phenolic cage and low-density ceramic balls reduces rotational mass, allowing for a very high limiting speed of 60,000 rpm and lower operating temperatures.
- Excellent Load Capacity: The 25° contact angle is optimized to handle substantial combined loads, making it ideal for applications with high radial and axial force components.
- Long-Term Reliability: The sealed and pre-lubricated construction protects against contaminants and retains lubrication, ensuring consistent performance and an extended service interval across the specified temperature range.
