Engineered with chrome steel components, it delivers high radial load capacity and reliable operation, making it an ideal choice for applications requiring robust performance and extended service life without maintenance.
6211-2RSNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6211 | Basic designation for a single row deep groove ball bearing with a 55mm bore, 100mm OD, and 21mm width. |
| 2RS | Contact rubber seals on both sides, providing superior protection against dust and moisture ingress. |
| NR | Snap ring groove on the outer ring, enabling easy axial positioning and simplified housing design. |
| /C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or where interference fits are used. |
6211-2RSNR/C3 Bearing Structural Features & Performance Benefits
Sealed & Protected Design: The 2RS double-contact rubber seals effectively shield the bearing interior from contaminants, ensuring long-term reliability and making it a maintenance-free solution for many applications.
High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 9757 lbf and a static load rating of 6609 lbf, providing robust performance under significant radial loads.
Simplified Assembly & Location: The integrated snap ring (NR) eliminates the need for complex housing shoulders or separate retaining components, reducing assembly time and cost.
Optimized Internal Clearance: The C3 clearance accommodates thermal expansion and interference fits, preventing premature failure in applications with elevated operating temperatures.
