6203-RSNR Bearing Product Overview & Core Advantages
The 6203-RSNR is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features a snap ring groove on its outer ring for secure axial location within a housing, simplifying assembly and enhancing operational stability. Its sealed construction provides robust protection against contaminant ingress, ensuring long service life and consistent performance under radial loads. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers excellent value for a wide range of industrial applications requiring dependable and cost-effective rotational motion control.
6203-RSNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard bearing series designation indicating a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| RS | Denotes contact rubber seals on both sides. This provides effective protection against dust and moisture, retaining lubricant and extending bearing life. |
| NR | Indicates a snap ring groove on the outer ring. This feature allows for simplified axial location and secure mounting within a housing, reducing the need for complex housing designs. |
6203-RSNR Bearing Structural Features & Performance Benefits
- Robust Sealing for Enhanced Reliability: The RS contact seals effectively shield the internal components from contaminants like dust and dirt. This results in a maintenance-free design with a long operational lifespan, even in challenging environments.
- Simplified Installation and Axial Location: The integrated snap ring groove (NR) on the outer diameter eliminates the need for complex shoulder machining in the housing. This feature ensures secure axial positioning, prevents bearing creep, and streamlines the assembly process.
- Optimized for Radial Loads: The deep groove raceway and single row design are engineered to efficiently handle significant radial dynamic and static loads (2147 lbf / 1079 lbf), providing stable and reliable performance.
- Precision and Consistency: Manufactured from high-grade chrome steel for all core components (rings, balls, cage) and conforming to ABEC 1 | ISO P0 tolerance class, this bearing ensures smooth running and consistent operation.
