S7013 CE/HCP4AQBCA Bearing Product Overview & Core Advantages
The S7013 CE/HCP4AQBCA is a high-precision quadruplex matched angular contact ball bearing designed for demanding applications requiring exceptional rigidity and rotational accuracy. This ceramic ball bearing features a back-to-back arrangement of four bearings, providing superior stability under combined loads (radial and axial). With its P4A tolerance class and phenolic cage, it delivers outstanding high-speed performance and is pre-lubricated for long-term, maintenance-free operation in a wide temperature range.
S7013 CE/HCP4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Hybrid Ceramic Balls (Silicon Nitride) | Reduced weight, lower friction, higher speed capability, and extended service life. |
| HC | Phenolic Resin Cage | Excellent strength-to-weight ratio, ideal for high-speed applications. |
| P4A | High Precision Tolerance Class (Superior to ABEC 7) | Guarantees extreme running accuracy and minimal vibration for precision machinery. |
| QBC | Quadruplex Back-to-Back Matched Set | Provides maximum rigidity and can accommodate moment loads in addition to combined radial and axial loads. |
S7013 CE/HCP4AQBCA Bearing Structural Features & Performance Benefits
- Exceptional Rigidity: The quadruplex back-to-back (QBC) configuration creates an extremely rigid bearing system, effectively resisting deflection under heavy combined loads and moment loads, which is critical for maintaining precision.
- Superior High-Speed Capability: The combination of hybrid ceramic balls and a lightweight phenolic cage (HC) significantly reduces centrifugal forces, enabling a high limiting speed of 36,000 rpm. The 15° contact angle is optimized for high-speed operation.
- High Load Capacity: Engineered to handle significant radial dynamic load ratings (12,150 lbf) and static load ratings (13,950 lbf), making it suitable for demanding applications.
- Pre-Lubricated & Sealed: Comes pre-filled with grease and is sealed, offering a long service life and maintenance-free operation within the specified temperature range (-30°C to 110°C).
S7013 CE/HCP4AQBCA Bearing Typical Application Areas
