6203-2RSNR Bearing Product Overview & Core Advantages
The 6203-2RSNR is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its core advantages stem from its sealed design and integrated snap ring, providing robust radial load capacity and simplified installation. This bearing is engineered for high-performance operation, offering a superior balance of durability and precision, making it an ideal choice for applications requiring long service life and minimal maintenance.
6203-2RSNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| 2RS | Signifies contact seals on both sides. This provides superior protection against contaminants and retains lubricant, enhancing bearing life. |
| NR | Indicates a snap ring groove on the outer ring. This feature allows for axial location and simplifies housing design by eliminating the need for a complex shoulder. |
6203-2RSNR Bearing Structural Features & Performance Benefits
- Robust Sealing: The double-sided contact seals (2RS) effectively shield the precision bearing internals from dust, moisture, and other contaminants, ensuring reliable operation in harsh environments and contributing to its maintenance-free characteristics.
- Simplified Assembly: The snap ring groove (NR) on the outer ring provides a positive axial location, securing the bearing within the housing without complex machining, reducing assembly time and cost.
- High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic and static load rating for its compact bearing dimensions (17mm x 40mm x 12mm), ensuring dependable performance under significant radial loads.
- Standardized Precision: Conforming to ABEC 1 | ISO P0 tolerance class and standard radial internal clearance (CN), it guarantees consistent and smooth running for a wide range of industrial applications.
6203-2RSNR Bearing Typical Application Areas
The 6203-2RSNR is versatile and commonly specified in:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
Its sealed and pre-lubricated design makes it particularly suitable for applications where re-lubrication is difficult or where operational environments are dusty or dirty.
