6211-2RSNRJEM Bearing Product Overview & Core Advantages
The 6211-2RSNRJEM is a high-performance single row deep groove ball bearing engineered for demanding industrial applications. This sealed bearing is designed to primarily accommodate radial loads while offering reliable operation and extended service life. Its key advantages include a robust construction using chrome steel components, a pre-lubricated and sealed design for minimal maintenance, and an integrated snap ring on the outer ring for simplified axial location and secure mounting within a housing. This combination makes it an excellent choice for applications requiring durability, ease of installation, and consistent performance.
6211-2RSNRJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6211 | Basic Bearing Designation | Indicates a single row deep groove ball bearing with a 55mm bore, 100mm OD, and 21mm width. |
| -2RS | Contact Seals (Rubber) | Features rubber seals on both sides, providing superior protection against contaminants and retaining lubricant. |
| NR | Snap Ring Groove | Specifies that the outer ring has a groove to accommodate a snap ring for axial location. |
| JEM | Snap Ring Supplied | Indicates that the bearing is supplied with the snap ring already fitted, simplifying the installation process. |
6211-2RSNRJEM Bearing Structural Features & Performance Benefits
Robust Construction & High Load Capacity: Manufactured entirely from chrome steel, this bearing offers excellent resistance to wear and fatigue. With a dynamic load rating of 9757 lbf and a static load rating of 6609 lbf, it is built to handle significant radial loads in continuous operation.
Enhanced Sealing & Maintenance-Free Operation: The -2RS rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants while securely retaining the factory-applied lubricant. This sealed design ensures long-term, maintenance-free performance across a wide temperature range of -30°C to 120°C.
Simplified Installation & Secure Positioning: The inclusion of a snap ring groove (NR) and the supplied snap ring (JEM) allows for quick and secure axial location of the bearing within a housing, eliminating the need for complex housing shoulders or locknuts. This feature is critical for simplifying assembly and ensuring reliable positioning.
Precision & Speed Performance: Manufactured to ABEC 1 | ISO P0 tolerance class with standard CN radial internal clearance, this bearing provides reliable, smooth operation suitable for a wide range of industrial applications, with a limiting speed of 6,300 rpm.
