6211-ZNR/C3 Bearing Product Overview & Core Advantages
The 6211-ZNR/C3 is a single row deep groove ball bearing designed for robust radial load applications. Its key advantage lies in the snap ring fitted on the outer ring, which provides secure axial positioning and simplifies housing design by eliminating the need for complex shoulder machining. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable performance for general industrial use. The combination of shielded construction and C3 radial internal clearance makes it suitable for applications with moderate operational speeds and thermal expansion requirements.
6211-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| Z | Single Shielded Side | Protects against contaminants from one side while maintaining low friction |
| NR | Snap Ring Groove with Snap Ring | Enables secure axial location, reduces housing complexity and costs |
| /C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion, ideal for applications with temperature variations |
6211-ZNR/C3 Bearing Structural Features & Performance Benefits
Snap Ring Design: The integrated snap ring (106.5 mm OD, 2.46 mm width) provides positive axial location, enhancing mounting stability and simplifying assembly in through-bore housings.
Radial Load Capacity: With a dynamic load rating of 9757 lbf and static load rating of 6609 lbf, this bearing delivers reliable performance under substantial radial loads.
Shielded Protection: The single-sided steel shield effectively retains lubrication and excludes larger contaminants, extending service life in typical industrial environments.
Optimized Clearance: The C3 clearance provides additional internal space to accommodate shaft expansion and misalignment, preventing premature failure in applications with thermal gradients.
Material Construction: Manufactured from chrome steel for rings, balls, and cage, ensuring consistent hardness, wear resistance, and dimensional stability.
