6203-2RS1/C4 GJN Bearing Product Overview & Core Advantages
The 6203-2RS1/C4 GJN is a sealed deep groove ball bearing engineered for demanding industrial applications requiring high reliability and consistent performance. This single row bearing is designed to accommodate primarily radial loads, while also handling moderate axial loads in both directions. Its key advantages include an optimized C4 radial internal clearance for specific operational conditions, and robust sealed construction that protects against contamination, making it an excellent choice for applications where maintenance-free operation is critical.
6203-2RS1/C4 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6203 | Standard Bearing Series & Size | Denotes a metric deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| -2RS1 | Sealing Type | Features contact rubber seals on both sides, providing superior protection against dust, moisture, and other contaminants. |
| /C4 | Radial Internal Clearance | Specifies a greater than normal (C4) clearance, suitable for applications with significant thermal expansion or where interference fits are used. |
| GJN | Grease Filling | Indicates the bearing is pre-lubricated with a specific, high-quality grease suitable for the stated temperature range. |
6203-2RS1/C4 GJN Bearing Structural Features & Performance Benefits
Robust Sealed Design: The 2RS1 double-contact rubber seals effectively retain lubrication and exclude pollutants, significantly extending bearing service life and enabling maintenance-free operation in harsh environments.
Optimized Internal Clearance: The C4 radial clearance is engineered for applications involving high operational temperatures or heavy interference fits, preventing excessive preload and potential seizure.
High-Quality Material Construction: Manufactured from chrome steel for both rings, balls, and cage, this bearing ensures high strength, durability, and consistent performance under dynamic and static loads.
Balanced Performance: With a radial dynamic load rating of 2147 lbf and a limiting speed of 17,000 rpm, it offers a reliable balance of load capacity and rotational speed for a wide range of industrial uses.
6203-2RS1/C4 GJN Bearing Typical Application Areas
This bearing's combination of sealing, clearance, and reliability makes it ideal for:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
