6211-2RS/C3 GJN Bearing Product Overview & Core Advantages
The 6211-2RS/C3 GJN is a metric single row deep groove ball bearing designed for robust performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering operational reliability. The bearing features integrated seals (2RS) for effective contamination exclusion and a greater than normal radial internal clearance (C3), making it particularly suitable for applications involving thermal expansion or where shaft fits may induce preload. Manufactured from high-grade chrome steel and compliant with ROHS and REACH directives, it is a versatile and dependable choice for industrial machinery.
Model Code In-Depth Explanation
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6211 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 55mm bore, 100mm OD, and 21mm width. |
| -2RS | Contact Rubber Seals on Both Sides | Provides excellent protection against contaminants and retains lubricant, enhancing bearing life. |
| /C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion and interference fits, preventing operational binding. |
| GJN | Grease Type Designation | Indicates the specific high-quality, lithium-based grease used for initial lubrication. |
6211-2RS/C3 GJN Bearing Structural Features & Performance Benefits
Sealed and Protected Design: The double-contact rubber seals (2RS) create an effective barrier against dust, moisture, and other particulate contaminants. This feature significantly extends the service interval and operational life of the bearing by preserving the integrity of the internal grease and rolling elements.
Optimized Internal Clearance: The C3 radial internal clearance is a critical feature for applications where thermal gradients are expected or where tight shaft and housing fits are used. This prevents excessive preload and the associated heat generation, ensuring smooth operation under varying thermal conditions.
Robust Load Capacity: With a dynamic load rating of 9757 lbf and a static load rating of 6609 lbf, this bearing is engineered to handle significant radial loads, providing reliable performance in heavy-duty applications.
Precision and Material Quality: Manufactured to ABEC 1 | ISO P0 tolerance class from high-carbon chrome steel for rings, balls, and cage, the bearing ensures consistent performance, durability, and a long operational lifespan.
6211-2RS/C3 GJN Bearing Typical Application Areas
