6211-2RS1/C3VT901 Bearing Product Overview & Core Advantages
The 6211-2RS1/C3 is a single row deep groove ball bearing designed for exceptional reliability in a wide range of industrial applications. Its core advantage lies in its ability to efficiently accommodate radial loads and moderate axial loads in both directions. The bearing features integral contact seals (2RS1) for robust contamination protection and is supplied with a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. This combination of sealed construction and optimized clearance provides a robust, long-lasting solution for demanding operating conditions.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6211 | Basic designation for a single row deep groove ball bearing with a 55mm bore. | Standardized dimensions for easy interchangeability. |
| 2RS1 | Bearing is equipped with two contact seals made from Nitrile Rubber (NBR). | Provides superior protection against contaminants and retains lubricant effectively. |
| C3 | Indicates a greater radial internal clearance than the standard C0 group. | Accommodates thermal expansion and interference fits, preventing operational issues. |
6211-2RS1/C3VT901 Bearing Structural Features & Performance Benefits
- Sealed for Life Design: The two NBR contact seals (2RS1) provide a highly effective barrier against dust, dirt, and moisture. This creates a maintenance-free solution, as the seals retain the factory-applied grease, extending service life in contaminated environments.
- Optimized Internal Clearance: The C3 clearance is a key performance feature. It allows for stable operation in applications where bearing rings are heated for mounting or where significant operational temperature differences exist between the inner and outer rings.
- Robust 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, ensuring durability under substantial radial loads.
- Standardized Precision: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing provides reliable performance for general industrial applications without the cost of ultra-high precision grades.
6211-2RS1/C3VT901 Bearing Typical Application Areas
