6203N/C3 Bearing Product Overview & Core Advantages
The 6203N/C3 is a single row deep groove ball bearing engineered for superior radial load capacity and reliable performance in demanding industrial applications. Its open design facilitates high-speed operation and allows for versatile lubrication options. A key structural feature is the snap ring groove on the outer ring, which simplifies axial location and secure mounting within a housing, reducing assembly complexity and cost. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, this bearing is optimized for applications with expected thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6203 | Basic Bearing Series & Size | Standard deep groove ball bearing with 17mm bore, 40mm OD, 12mm width. |
| N | Snap Ring Groove | Outer ring has a groove for a snap ring, enabling simplified axial location and secure housing fit. |
| C3 | Radial Internal Clearance | Greater than normal clearance, suitable for applications with thermal expansion or interference fits. |
6203N/C3 Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The single row deep groove construction is primarily designed to support high radial loads efficiently.
- Simplified Mounting and Axial Location: The snap ring groove (N) on the outer ring eliminates the need for complex housing shoulders or end caps, providing a cost-effective and secure mounting solution.
- Operational Flexibility: The open seal type allows for high rotational speeds and permits the use of various lubrication systems to match specific application requirements.
- Robust Construction: All core components—rings, balls, and cage—are manufactured from chrome steel, ensuring high strength, durability, and consistent performance.
- Controlled Internal Clearance: The C3 clearance is engineered to accommodate shaft and housing fits that cause bearing ring expansion, or to handle operational heat, preventing premature failure due to excessive preload.
6203N/C3 Bearing Typical Application Areas
The 6203N/C3 is widely used in applications requiring reliable radial support and simplified mounting. Key sectors include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
