S7015 ACD/HCP4ADGA Bearing Product Overview & Core Advantages
The S7015 ACD/HCP4ADGA is a metric double row angular contact ball bearing engineered for ultra-high precision and exceptional performance. Its primary advantage lies in its ability to support combined loads—simultaneously handling significant radial loads and bidirectional axial loads. This is achieved through its optimized 25° contact angle and universal matchable (SU) design, which allows for flexible mounting arrangements. Manufactured to the stringent P4A tolerance class, it delivers superior running accuracy, making it ideal for applications demanding high rigidity and high rotational speeds.
S7015 ACD/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| ACD | 25° contact angle, double row design | Optimized for handling combined radial and axial loads. |
| HC | Hybrid Ceramic (Silicon Nitride balls) | Enables higher speeds, reduced friction, and longer service life. |
| P4A | High Precision Tolerance Class (ABEC 7/ISO P4) | Guarantees ultra-precise running accuracy and minimal vibration. |
| DGA | Sealed on both sides, pre-lubricated with grease | Provides effective contamination exclusion and is maintenance-free. |
S7015 ACD/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides a rigid support system, significantly increasing the bearing's capacity to handle combined loads and moment loads compared to single row designs.
- Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-friction ceramic balls reduces centrifugal forces and operating temperatures, allowing for a high limiting speed of 22,000 rpm.
- Precision & Accuracy: Manufactured to P4A super-precision standards with tight bore and OD tolerances, this bearing ensures minimal runout and vibration for smooth, precise operation.
- Maintenance-Free & Long Life: The integral seals and factory-applied grease lubrication protect against contaminants and provide reliable operation across a wide temperature range without the need for re-lubrication.
S7015 ACD/HCP4ADGA Bearing Typical Application Areas
