6203-2RSNR/C3 Bearing Product Overview & Core Advantages
The 6203-2RSNR/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This metric bearing features an integral snap ring and contact seals, making it a robust and reliable solution. Its core advantages include the ability to handle significant radial loads, simplified axial location via the snap ring, and effective protection against contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it is designed for high reliability and stable operation under a wide temperature range.
6203-2RSNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6203 | Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. | Defines the core dimensions and bearing type. |
| 2RS | Indicates contact seals on both sides of the bearing. | Provides superior protection against contaminants like dust and moisture, retaining lubricant for extended service life. |
| NR | Specifies a snap ring groove on the outer ring. | Allows for simplified axial location and secure mounting within a housing, reducing assembly complexity and cost. |
| /C3 | Denotes a greater than normal radial internal clearance. | Ideal for applications with expected thermal expansion, such as in electric motors, ensuring stable performance under varying temperatures. |
6203-2RSNR/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built from chrome steel for both rings, balls, and cage, this bearing offers high strength and durability. With a dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, it is well-suited for applications with significant radial loads.
- Effective Sealing & Contamination Resistance: The 2RS contact seals provide a high degree of protection against the ingress of solid particles and moisture. This feature is critical for maintaining bearing integrity and lubrication in harsh environments.
- Simplified Installation & Axial Location: The integrated snap ring groove (NR) on the outer ring eliminates the need for complex housing shoulders or end caps, facilitating quicker and more cost-effective assembly while ensuring secure axial positioning.
- Optimized Internal Clearance for Thermal Stability: The C3 radial clearance provides extra space for thermal expansion of the bearing components and the surrounding structure. This prevents pre-loading and potential seizure in applications with elevated operating temperatures.
6203-2RSNR/C3 Bearing Typical Application Areas
The 6203-2RSNR/C3 is a versatile component ideal for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Material Handling Equipment
