6209-RSN-ZNR Bearing Product Overview & Core Advantages
The 6209-RSN-ZNR is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its key advantage lies in its sealed design, which provides robust protection against contaminants, making it an ideal maintenance-free solution. This bearing is designed to primarily handle radial loads and is characterized by its high limiting speed and consistent performance across a wide temperature range, ensuring long service life and operational stability.
6209-RSN-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6209 | Standard designation for a single row deep groove ball bearing with a 45mm bore and 85mm outside diameter. | Defines the core bearing dimensions and type. |
| RS | Contact rubber seal on one side. | Effective sealing against dust and moisture ingress. |
| N | Snap ring groove on the outer ring. | Facilitates secure axial location and simplified housing design. |
| ZNR | Combination of a snap ring groove (N) and a specific seal arrangement. | Offers both ease of mounting and sealed protection. |
6209-RSN-ZNR Bearing Structural Features & Performance Benefits
Sealed for Protection & Longevity: The integrated contact seals (RS) effectively shield the internal rolling elements and raceways from contaminants, significantly extending bearing service life and enabling operation in harsh environments without relubrication.
Snap Ring Groove for Secure Location: The outer ring features a snap ring groove (N), allowing for positive axial location within the housing. This simplifies assembly, reduces the need for complex housing shoulders, and enhances the overall rigidity of the assembly.
Optimized for High-Speed Operation: Manufactured to ABEC 1 | ISO P0 tolerance class with standard radial internal clearance (CN), this bearing ensures smooth, low-vibration, and high-speed performance up to its limiting speed of 7,700 rpm.
Robust Load Capacity: With a dynamic load rating of 7351 lbf and a static load rating of 4564 lbf, the 6209-RSN-ZNR is built to handle significant radial loads reliably.
6209-RSN-ZNR Bearing Typical Application Areas
