6203/C3MT Bearing Product Overview & Core Advantages
The 6203/C3MT is a high-performance single row deep groove ball bearing designed for robust industrial applications. Engineered to primarily handle radial loads, it also accommodates moderate axial loads in both directions. Its defining feature is the C3 radial internal clearance, which makes it exceptionally suitable for applications involving thermal expansion, heavy loads, or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable precision and consistent performance, ensuring operational stability and longevity in demanding environments.
6203/C3MT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6203 | Standard bearing series with 17mm bore, 40mm OD, 12mm width. | Defines the core bearing dimensions for interchangeability. |
| C3 | Specifies a greater than normal radial internal clearance. | Prevents binding under thermal expansion or heavy loads, enhancing reliability. |
| MT | Indicates the bearing is supplied with a high-temperature, lithium-based grease. | Provides initial lubrication for immediate operation and extends service life. |
6203/C3MT Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel construction ensure smooth operation and efficient load distribution, contributing to a high radial dynamic load rating of 2147 lbf.
- Enhanced Operational Stability: The C3 clearance is critical for applications with expected temperature fluctuations or heavy loads, preventing premature failure due to thermal expansion or press fits.
- High-Speed Capability: The single-piece crown-type steel cage and precision grinding enable a high limiting speed of 17,000 rpm, making it a capable high-speed bearing.
- Durability and Compliance: Manufactured from through-hardened chrome steel for both rings, balls, and cage, it offers excellent wear resistance. The bearing is also ROHS and REACH compliant, meeting stringent environmental standards.
6203/C3MT Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of industrial machinery, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
