S71913 ACE/HCP4A Bearing Product Overview & Core Advantages
The S71913 ACE/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This single-row bearing features a 25° contact angle, enabling it to support combined radial and axial loads simultaneously. Manufactured to P4 (ABEC-7) tolerance class, it guarantees superior running accuracy and rotational precision. Its compact design, combined with ceramic balls and a phenolic cage, makes it an ideal solution for high-speed and high-rigidity applications where reliability is critical.
S71913 ACE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| ACE | 25° contact angle, phenolic cage, preloaded | Optimized for high rigidity and precise operation under combined loads. |
| HC | Hybrid Ceramic (Ceramic balls, steel rings) | Reduced friction, lower operating temperature, and extended service life at high speeds. |
| P4A | P4 (ABEC-7) tolerance class | Ensures extremely high running accuracy and minimal vibration for precision machinery. |
S71913 ACE/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The 25° contact angle and built-in preload provide superior system stiffness, minimizing deflection under load for enhanced machining or positioning accuracy.
- Exceptional High-Speed Capability: The combination of ceramic balls (lower density than steel) and a lightweight phenolic cage significantly reduces centrifugal forces, enabling a high limiting speed of 22,000 rpm.
- Superior Load Capacity: Engineered to handle significant combined radial and axial loads, with a dynamic load rating of 3510 lbf and a static load rating of 2610 lbf.
- Long-Term Reliability & Low Maintenance: The bearing is pre-lubricated and sealed, protecting against contamination and retaining lubricant, which ensures consistent performance and reduces maintenance needs.
- Wide Operating Temperature Range: Suitable for use in environments from -30°C to 110°C, offering flexibility for various industrial conditions.
