S7006 CE/HCDBAVQ126 Bearing Product Overview & Core Advantages
The S7006 CE/HCDBAVQ126 is a precision duplex angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This matched back-to-back arrangement provides superior rigidity and can accommodate combined radial and axial loads from both directions. Manufactured to P4A super-precision tolerance and featuring ceramic balls, it delivers outstanding high-speed capability, reduced heat generation, and extended service life in high-performance machinery.
S7006 CE/HCDBAVQ126 Bearing Model Code Explained, Specifications & Naming Convention
- S7006: Basic bearing series and size designation (30mm bore, 55mm OD)
- C: 15° contact angle for optimal axial load capacity
- E: High-precision P4A tolerance class
- HC: Hybrid ceramic construction with silicon nitride balls
- DB: Duplex Back-to-Back matched arrangement
- AV: Extra light preload (Class A)
- Q126: Specific internal design and grease lubrication
S7006 CE/HCDBAVQ126 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with ceramic balls significantly reduces friction, heat generation, and wear, enabling higher limiting speeds (100,500 rpm) and longer service life compared to all-steel bearings.
Duplex Back-to-Back Design: This matched arrangement creates a rigid bearing system that provides precise axial positioning and excellent resistance to moment loads, making it ideal for applications requiring high rotational accuracy.
Super-Precision P4A Tolerance: With bore and outside diameter tolerances of -0.004mm to 0, this bearing ensures minimal runout and vibration for superior rotational precision in demanding applications.
Phenolic Cage & Sealed Design: The phenolic resin cage offers excellent strength at high speeds, while the sealed construction protects against contamination and retains lubrication for reliable operation.
