S7013 ACE/HCP4AQBCB Bearing Product Overview & Core Advantages
The S7013 ACE/HCP4AQBCB is a high-precision quadruplex matched bearing set designed for the most demanding applications requiring exceptional rigidity and rotational accuracy. This metric angular contact ball bearing features a back-to-back (QBC) arrangement of four bearings, providing superior stability and the ability to handle combined loads (radial and axial) simultaneously. Manufactured to ABEC 7 / P4A tolerance class with ceramic balls and a phenolic cage, it delivers outstanding high-speed performance, reduced heat generation, and extended service life in precision machinery.
S7013 ACE/HCP4AQBCB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| S7013 | Series & Size Designation | Indicates a 65mm bore, 100mm OD, and 18mm single bearing width. |
| ACE | 25° Contact Angle & Enhanced Design | Optimized for high axial load capacity and high-speed operation. |
| HC | Hybrid Ceramic | Silicon Nitride (Si3N4) balls reduce weight, friction, and heat, enabling higher speeds. |
| P4A | Tolerance Class (ABEC 7) | Guarantees ultra-precise running accuracy and dimensional stability. |
| QBC | Quadruplex Back-to-Back | A matched set of 4 bearings pre-configured for maximum moment stiffness. |
S7013 ACE/HCP4AQBCB Bearing Structural Features & Performance Benefits
- Exceptional Rigidity: The quadruplex back-to-back (QBC) arrangement creates an extremely rigid bearing system that effectively resists moment loads and shaft deflection, which is critical for maintaining precision in machine tool spindles and other high-performance equipment.
- Superior High-Speed Capability: The combination of hybrid ceramic balls and a lightweight phenolic resin cage significantly reduces centrifugal forces and operating temperatures. This allows the bearing to achieve a high limiting speed of 31,000 rpm with minimal wear.
- Optimized Load Capacity: With a 25° contact angle and a dynamic load rating of 11,408 lbf, this bearing is engineered to handle significant combined radial and axial loads simultaneously, ensuring reliable performance under complex loading conditions.
- Pre-Configured & Sealed for Reliability: The set is supplied as a matched quadruplex unit with a light preload (Class B) applied, ensuring optimal performance without the need for on-site adjustment. The sealed design retains factory-applied grease and protects against contamination.
S7013 ACE/HCP4AQBCB Bearing Typical Application Areas
