1203 C/3 Bearing Product Overview & Core Advantages
The 1203 C/3 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design and is constructed from high-grade chrome steel for superior performance. Its primary advantage lies in its ability to accommodate significant radial loads, making it an ideal choice for compact spaces where robust support is essential. The bearing is pre-lubricated, ensuring immediate operation and reducing initial setup complexity.
1203 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| C/3 | Indicates a specific internal design and radial internal clearance group of C3, which is greater than normal clearance, suitable for applications with thermal expansion or where interference fits are used. |
1203 C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides enhanced rigidity and enables the bearing to support substantial radial loads (Dynamic: 1989 lbf, Static: 495 lbf), ensuring stable operation under demanding conditions.
- Optimized Cage Design: The nylon cage contributes to smooth operation, lower friction, and is suitable for high-speed applications, supporting a limiting speed of 24,000 rpm.
- Precision Engineering: Manufactured with tight dimensional tolerances on the bore diameter (17 mm), outside diameter (40 mm), and width (12 mm), ensuring precise fit and reliable performance in high-accuracy assemblies.
- Material Integrity: Both rings and balls are made from chrome steel, offering excellent wear resistance and durability, suitable for a wide temperature range of -30°C to 110°C.
