6203-2RSL/C3GJN Bearing Product Overview & Core Advantages
The 6203-2RSL/C3GJN is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. Its core advantage lies in its ability to handle significant radial loads while offering protection against contamination. Featuring integrated seals and a C3 radial internal clearance, this bearing is engineered for stable operation in applications with thermal expansion or where a tighter fit is required. Constructed entirely from chrome steel, it provides excellent durability and is suitable for a wide operating temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard series designation for a medium-duty, single row deep groove ball bearing with a 17mm bore. |
| 2RS | Contact seals on both sides, providing effective protection against contaminants and retaining lubricant. |
| L | Indicates the use of a lightweight, pressed steel cage. |
| C3 | Radial internal clearance greater than normal (CN), suitable for applications with shaft interference fits or elevated operating temperatures. |
| GJN | Specifies a standard grade, polyurea-thickened grease lubricant, offering a wide temperature range and long service life. |
6203-2RSL/C3GJN Bearing Structural Features & Performance Benefits
Sealed Design for Enhanced Reliability: The double-sided contact seals (2RS) effectively shield the bearing's interior from dust, moisture, and other contaminants, while also retaining the factory-applied grease. This results in a maintenance-free and long-lasting solution, reducing downtime and total cost of ownership.
Optimized Internal Clearance for Stable Operation: The C3 radial clearance provides extra space between the rolling elements and raceways. This is critical for applications prone to thermal expansion, preventing preload and ensuring smooth, low-vibration operation under varying thermal conditions.
Robust Construction for High Load Capacity: Manufactured from high-quality chrome steel for all core components (rings, balls, cage), this bearing delivers a high dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, ensuring reliable performance under substantial radial stresses.
6203-2RSL/C3GJN Bearing Typical Application Areas
The 6203-2RSL/C3GJN is a versatile component widely used across various industries due to its sealed and robust nature. Common applications include:
- Electric Motors: Ideal for fan ends and drive shafts in industrial and automotive motors.
- Material Handling Equipment: Conveyor rollers, pulley systems, and gearboxes.
- Agricultural Machinery: Implement wheels, idlers, and drives in harsh, dusty environments.
- Industrial Pumps and Compressors: Shaft support where sealing is paramount to prevent fluid ingress.
- General Machinery: A reliable choice for a wide range of machinery requiring a standard-sized, pre-lubricated, and sealed ball bearing.
