S7013 ACE/HCP4ADGA Bearing Product Overview & Core Advantages
The S7013 ACE/HCP4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to simultaneously handle combined loads (radial and axial), this bearing features a universal matchable (SU) design, allowing two bearings to be paired for optimal performance. Its ceramic balls and P4A super precision tolerance ensure superior high-speed capability and minimal rotational vibration, making it ideal for high-rigidity spindle applications.
S7013 ACE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| ACE | 25° contact angle, Extra light preload | Optimized for high-speed operation with minimal friction |
| HC | Hybrid Ceramic (Silicon Nitride balls) | Enhanced speed capability, reduced weight, and longer service life |
| P4A | ABEC 7 / ISO P4A super precision tolerance | Exceptional running accuracy for precision applications |
| DGA | Sealed, Grease lubricated | Contamination protection and maintenance-free operation |
S7013 ACE/HCP4ADGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, enabling higher limiting speeds (31,000 rpm) while providing electrical insulation properties.
High Rigidity Design: The 25° contact angle and universal matchable arrangement create a stiff bearing system capable of handling substantial axial loads in both directions while maintaining precision.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration in high-speed applications.
Optimized Lubrication System: Pre-greased with high-performance lubricant suitable for the temperature range of -30°C to 110°C, combined with effective sealing for long-term, maintenance-free operation.
