S7014 CE/HCP4AQBCA Bearing Product Overview & Core Advantages
The S7014 CE/HCP4AQBCA is a super-precision quadruplex matched bearing set designed for the most demanding high-speed and high-rigidity applications. This metric angular contact ball bearing set, configured in a back-to-back (QBC) arrangement, is engineered to handle significant combined loads (radial and axial) simultaneously. Its P4A tolerance class and use of ceramic balls ensure exceptional running accuracy, low heat generation, and extended service life, making it ideal for ultra-precise spindles.
S7014 CE/HCP4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
The model number S7014 CE/HCP4AQBCA is decoded as follows:
- S70: Super-precision angular contact ball bearing series.
- 14: Bore diameter code (70 mm).
- CE: Ceramic balls (Silicon Nitride).
- HC: Phenolic (Hybrid Composite) cage.
- P4A: High-precision tolerance class (exceeding ABEC 7/ISO P4).
- QBC: Quadruplex (4 bearings) matched set in a Back-to-Back arrangement.
S7014 CE/HCP4AQBCA Bearing Structural Features & Performance Benefits
- Extreme Rigidity & Load Capacity: The quadruplex back-to-back (QBC) matched arrangement provides exceptional system stiffness, enabling precise control under heavy combined loads and complex moment loads.
- Superior High-Speed Performance: The combination of lightweight phenolic cage and ceramic balls reduces centrifugal forces and friction, allowing for a high limiting speed of 22,000 rpm. The 15° contact angle is optimized for high-speed operation.
- Pre-Lubricated & Sealed: Factory-filled grease lubrication and integrated seals provide long-term, maintenance-free operation within the specified temperature range.
- Ultra-Precision: Manufactured to P4A tolerance class with tightly controlled bore and outside diameter tolerances, ensuring minimal runout and vibration for superior machining finish and accuracy.
