6203/C2 Bearing Product Overview & Core Advantages
The 6203/C2 is a single row deep groove ball bearing designed for exceptional performance in general industrial applications. Characterized by its open design and C2 radial internal clearance, this bearing is engineered to accommodate radial loads efficiently while offering moderate axial load capacity in both directions. Its metric dimensions (17mm bore, 40mm OD) and compact 12mm width make it a versatile and space-saving solution. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable operation and is an excellent choice for applications requiring a balance of cost-effectiveness and dependable performance.
6203/C2 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance |
|---|---|---|
| 6203 | Basic Bearing Series & Size | Denotes a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| /C2 | Radial Internal Clearance Group | Indicates a clearance smaller than the Normal (CN) group. This is beneficial for applications requiring precise shaft positioning, reduced noise, and where operating temperatures are moderate. |
6203/C2 Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel construction enable smooth operation and effective handling of radial dynamic loads up to 2147 lbf.
- Precision Cage for Stability: The chrome steel cage ensures uniform ball spacing and guidance, contributing to stable operation at the specified limiting speed of 17,000 rpm.
- Controlled Internal Clearance: The C2 clearance provides a tighter fit between the rolling elements and raceways, resulting in better shaft guidance and lower noise levels in precision assemblies.
- Broad Operating Range: With a temperature range from -30°C to 120°C and no pre-applied lubrication, it offers flexibility for the end-user to select the optimal lubricant for their specific application conditions.
6203/C2 Bearing Typical Application Areas
