6206-2ZTN9/HC5C3WT Bearing Product Overview & Core Advantages
The 6206-2ZTN9/HC5C3WT is a single row deep groove ball bearing engineered for high-performance applications demanding reliability and precision. This metric bearing is distinguished by its hybrid ceramic construction, utilizing silicon nitride balls for superior performance. Its core advantages include the ability to handle significant radial loads, excellent high-speed capabilities, and extended service life due to its advanced material composition and shielded design. The bearing is pre-set with a C3 radial internal clearance, making it suitable for applications with thermal expansion considerations.
6206-2ZTN9/HC5C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6206 | Standard deep groove ball bearing series with 30mm bore, 62mm OD. |
| 2Z | Bearing is equipped with shields on both sides to protect against contaminant ingress. |
| TN9 | Polyamide (Nylon) cage, snap-type design, contributing to low friction, quiet operation, and high-speed suitability. |
| HC5 | Hybrid Ceramic designation, indicating Silicon Nitride (Si3N4) balls. |
| C3 | Specifies a greater than normal radial internal clearance for applications involving thermal expansion. |
| WT | Variant code, often related to specific material or process treatments. |
6206-2ZTN9/HC5C3WT Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride (Si3N4) balls results in a bearing with significantly reduced friction, higher stiffness, and superior performance at high speeds. This hybrid design also offers enhanced resistance to electrical erosion and can operate with less lubrication.
High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces, while the low-friction ceramic balls allow for a high limiting speed of 11,000 rpm. This makes it an ideal high-speed bearing for demanding applications.
Robust Load Capacity: Despite its compact bearing dimensions (30mm bore, 62mm OD, 16mm width), it maintains a high dynamic load rating, ensuring reliable operation under substantial radial loads.
Contamination Protection & Longevity: The 2Z non-contact shields on both sides effectively protect the bearing interior from dust and debris, extending its operational life and reducing maintenance needs.
6206-2ZTN9/HC5C3WT Bearing Typical Application Areas
