S7006 FE/HCP4ADT Bearing Product Overview & Core Advantages
The S7006 FE/HCP4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. This matched duplex tandem (DT) arrangement provides superior axial rigidity and is preloaded for immediate, precise operation. Featuring a ceramic ball construction and P4A super-precision tolerance, it delivers high-speed capability, extended service life, and reliable operation under combined radial and axial loads. The sealed design with factory-applied grease ensures long-term, maintenance-free performance.
S7006 FE/HCP4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 26mm width). |
| FE | Indicates a sealed bearing, protecting against contamination. |
| HC | Signifies the use of Hybrid Ceramic balls (steel rings, ceramic balls). |
| P4A | Denotes a super-precision tolerance class for high-precision applications. |
| ADT | Specifies a Duplex Tandem (DT) arrangement with preload. |
S7006 FE/HCP4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex tandem arrangement and 18° contact angle are engineered to handle significant combined loads, providing maximum axial stiffness and precise shaft positioning.
- Superior High-Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage allows for a very high limiting speed of 100,500 rpm, making it an ideal high-speed bearing.
- Extended Service Life & Reliability: Hybrid ceramic construction offers excellent wear resistance and reduced electrical arcing. The sealed design and pre-applied grease provide consistent lubrication, resulting in maintenance-free operation and long-term reliability.
- Precision Engineering: Manufactured to P4A tolerance class with tight bearing dimensions and runout control, ensuring smooth, quiet, and accurate performance in precision machinery.
