S7013 ACE/HCP4BVG275 Bearing Product Overview & Core Advantages
The S7013 ACE/HCP4BVG275 is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional speed, rigidity, and accuracy. Its single-row design with a 25° contact angle is optimized to handle significant combined loads—simultaneous radial and axial forces. Manufactured to a P4 (ABEC-7) tolerance class, it guarantees superior running accuracy and rotational stability. The bearing is preloaded and comes sealed and pre-lubricated, making it a ready-to-install, high-performance solution for high-speed spindles and precision machinery.
S7013 ACE/HCP4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S7013 | Basic bearing series and size (65mm bore, 100mm OD). | Defines the core bearing dimensions. |
| ACE | Internal design code for optimized contact angle and internal geometry. | Enhances high-speed performance and load capacity. |
| HC | Hybrid Ceramic: Ceramic balls with steel rings. | Reduces weight and friction, increases limiting speed, and provides electrical insulation. |
| P4 | Tolerance class (ABEC-7). | Ensures ultra-high precision and minimal runout for critical applications. |
| BVG275 | Specific sealing and high-performance grease type. | Offers effective contamination protection and reliable lubrication within the specified temperature range. |
S7013 ACE/HCP4BVG275 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls (Si3N4) significantly reduces centrifugal forces, lowers operating temperature, and enables a very high limiting speed of 20,000 rpm. This construction also mitigates electrical arcing damage.
- Phenolic Resin Cage: The lightweight and robust phenolic cage ensures excellent guidance and stability of the ceramic balls at ultra-high speeds, contributing to smooth operation and reduced vibration.
- 25° Contact Angle & Preload: The optimized contact angle provides superior axial load capacity and rigidity. The bearing is supplied with a preload, which eliminates internal clearance, resulting in enhanced system stiffness and precise rotational accuracy.
- Sealed & Pre-Lubricated: The integrated seals protect against contaminants, while the factory-applied high-speed grease ensures immediate operation and long-term, maintenance-free performance within its operational temperature range.
S7013 ACE/HCP4BVG275 Bearing Typical Application Areas
