| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| -2RS | Contact Seals on Both Sides | Provides effective protection against contaminants and retains lubricant, enhancing bearing life. |
| NR | Snap Ring Groove on Outer Ring | Allows for secure axial location within a housing, simplifying design and assembly. |
| /C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion and heavy interference fits, preventing operational issues. |
| Q66/HT51 | Specific Cage Designation / Material | Indicates a robust cage construction, contributing to the bearing's stability and limiting speed. |
6206-2RSNR/C3 Q66/HT51 Bearing Structural Features & Performance Benefits
- Sealed & Protected Design: The contact seals (2RS) on both sides effectively shield the chrome steel rolling elements and raceways from dust, moisture, and other contaminants. This built-in protection ensures long-term performance reliability and reduces maintenance needs.
- Secure Axial Location: The snap ring groove (NR) on the outer ring provides a positive locating feature, preventing creep and simplifying housing design by eliminating the need for complex end caps or shoulders.
- Optimized Internal Clearance: The C3 radial clearance is engineered for applications where thermal expansion or press fits are a factor. This prevents pre-loading and potential bearing failure, ensuring smooth operation under varying conditions.
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a dynamic load rating of 4384 lbf and a static load rating of 254 lbf, providing durability for continuous operation.
