6208-2RSNR Bearing Product Overview & Core Advantages
The 6208-2RSNR is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing features an integrated snap ring on its outer ring for simplified axial location and a robust sealed design for enhanced contamination protection. Its construction from high-grade chrome steel ensures durability and reliable operation under significant radial loads, making it an ideal choice for applications requiring high reliability and long service life without maintenance.
6208-2RSNR Bearing Model Code Explained, Specifications & Naming Convention
- 6208: Basic designation for a single row deep groove ball bearing with a 40mm bore and 80mm OD.
- -2RS: Signifies that the bearing is equipped with contact seals on both sides. This provides effective protection against contaminants and retains lubricant.
- NR: Indicates the presence of a snap ring groove on the outer ring. This feature allows for simplified axial location within a housing, reducing assembly complexity and cost.
6208-2RSNR Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The 2RS contact seals effectively shield the internal components from dust, moisture, and other contaminants, while also retaining lubricant. This design significantly extends bearing life in harsh environments and supports a maintenance-free operation.
High Load Capacity: Manufactured from high-carbon chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 6542 lbf and a static load rating of 4002 lbf, ensuring reliable performance under substantial radial loads.
Simplified Assembly with Snap Ring: The outer ring snap ring (NR) eliminates the need for complex housing shoulders or end caps, facilitating easier and more cost-effective installation and axial positioning.
Precision and Consistency: Built to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, this bearing offers dependable performance for a wide range of general industrial applications.
