S7014 ACE/HCP4ADGA Bearing Product Overview & Core Advantages
The S7014 ACE/HCP4ADGA is a precision double-row angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. Engineered with a 25° contact angle and P4A super-precision tolerance, it excels at simultaneously handling combined radial and bidirectional axial loads. Its compact design, featuring ceramic balls and a phenolic cage, is optimized for high-speed operation and offers superior rigidity and long-term performance in critical machinery.
S7014 ACE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ACE | Specific internal design and clearance | Optimized for high-speed, high-precision performance. |
| HC | Hybrid Ceramic (Silicon Nitride Balls) | Reduced weight, lower friction, and extended service life. |
| P4A | Super Precision Tolerance Class | Guarantees extreme running accuracy and minimal vibration. |
| DGA | Contact Angle (25°) and Universal Match (SU) | Enables handling of bidirectional thrust loads and simplified mounting in preloaded sets. |
S7014 ACE/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double-row angular contact design provides a rigid support system, effectively managing significant combined loads (radial and axial) from both directions. With a dynamic load rating of 8190 lbf and static load rating of 7762 lbf, it ensures reliable operation under strenuous conditions.
Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage minimizes centrifugal forces and friction, enabling a high limiting speed of 22,000 rpm. This makes it an ideal high-speed bearing for precision spindles.
Pre-Lubricated & Sealed for Longevity: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is maintenance-free within its specified temperature range of -30°C to 110°C.
S7014 ACE/HCP4ADGA Bearing Typical Application Areas
- Machine Tool Spindles: High-precision milling, grinding, and turning centers.
- High-Speed Machining Centers: Where exceptional accuracy and rigidity are paramount.
- Precision Instrumentation: Medical devices, optical scanners, and measuring equipment.
