6211-2RS2/C3HT Bearing Product Overview & Core Advantages
The 6211-2RS2/C3HT is a sealed single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing excels at handling primarily radial loads while offering reliable operation across a wide temperature range. Its key advantages include a C3 radial internal clearance for thermal expansion management in high-temperature environments, and integral contact seals (2RS2) that effectively protect against contamination, ensuring long service life and reduced maintenance needs.
6211-2RS2/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Model Suffix | Technical Meaning | Benefit |
|---|---|---|
| 6211 | Basic designation: 55mm bore, 100mm OD, 21mm width | Defines standard bearing dimensions for interchangeability. |
| 2RS2 | Double-sided contact seals made of NBR rubber | Superior protection against contaminants like dust and moisture, retaining lubricant. |
| C3 | Radial internal clearance greater than normal | Accommodates thermal expansion in high-temperature applications, preventing seizure. |
| HT | High-Temperature capability | Indicates suitability for the specified temperature range of -30°C to 120°C. |
6211-2RS2/C3HT Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring high strength, durability, and consistent performance under load.
- Optimized Load Capacity: With a dynamic load rating of 9757 lbf and a static load rating of 6609 lbf, this bearing is designed to handle significant radial loads reliably.
