6211-2RS1/C3 Bearing Product Overview & Core Advantages
The 6211-2RS1/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This sealed bearing is designed to handle significant radial loads while offering reliable operation across a wide temperature range. Its key advantages include robust construction with chrome steel components, a high limiting speed of 6,300 rpm, and a generous C3 radial internal clearance suitable for applications with thermal expansion or heavy loads. The integrated seals provide excellent contamination protection, making it a durable and maintenance-friendly solution for industrial machinery.
6211-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6211 | Basic Bearing Series & Size | Indicates a standard deep groove ball bearing with a 55mm bore, 100mm OD, and 21mm width. |
| 2RS1 | Contact Seals on Both Sides | Features Nitrile Rubber (NBR) seals that provide superior protection against contaminants and retain lubricant effectively. |
| C3 | Radial Internal Clearance | Specifies a clearance greater than normal, ideal for applications with high operational temperatures or heavy loads to prevent binding. |
6211-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 9,757 lbf and a static load rating of 6,609 lbf, ensuring reliable performance under substantial radial stresses.
- Enhanced Sealing & Protection: The 2RS1 contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, significantly extending service life and reducing maintenance needs in harsh environments.
- Optimized Internal Clearance: The C3 clearance provides operational flexibility, accommodating shaft misalignments and thermal expansion without compromising performance, which is critical for high-speed applications up to 6,300 rpm.
- Precision & Consistency: Built to ABEC 1 | ISO P0 tolerance standards, this bearing offers dependable dimensional accuracy and running smoothness for a wide range of industrial uses.
