6203 TN9/C3 Bearing Product Overview & Core Advantages
The 6203 C3 is a single row deep groove ball bearing designed for reliable performance in general industrial applications. Engineered with precision ABEC 1 | ISO P0 tolerances, it offers a robust solution for carrying primarily radial loads. Its open design allows for versatile lubrication options, while the specified C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used, ensuring consistent operation under varying conditions.
6203 TN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Basic bearing series and size designation (17mm bore, 40mm OD, 12mm width). |
| C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with expected temperature variations or shaft/ housing interference fits, preventing preload and potential bearing seizure. |
| (No Seal Suffix) | The bearing is open, meaning it has no integral seals or shields. This allows for high-speed operation and custom lubrication regimes but requires a clean operating environment or external sealing. |
6203 TN9/C3 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and chrome steel construction enable efficient handling of significant radial dynamic load ratings (2147 lbf) and static loads (1079 lbf).
- High-Speed Capability: Featuring a lightweight nylon cage, this bearing achieves a high limiting speed of 17,000 rpm. The open design minimizes friction and heat generation from seals.
- Flexible Application & Maintenance: The open seal type provides maximum flexibility for initial lubrication and re-lubrication, allowing engineers to select the optimal grease or oil for specific operating conditions.
- Robust Construction: Manufactured from high-grade chrome steel for both rings and balls, ensuring durability and a long service life under standard operating temperatures (-30°C to 120°C).
6203 TN9/C3 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and small machinery
- Power Tools and gearboxes
- Material Handling Equipment such as conveyor rollers
- Agricultural Machinery
- Pumps and fans
