1203 C/2 Bearing Product Overview & Core Advantages
The 1203 C/2 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliability. This open-type bearing features a cylindrical bore and is designed to accommodate significant radial loads while maintaining stable operation. Its double row ball construction provides enhanced rigidity and load-carrying capacity compared to single row designs. Pre-lubricated and built with chrome steel components, it offers excellent durability and is suitable for a wide operating temperature range from -30°C to 110°C, making it a robust solution for demanding industrial environments.
1203 C/2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1203 | Standard bearing designation indicating a metric double row angular contact ball bearing with a 17mm bore diameter, 40mm outside diameter, and 12mm width. |
| C | Specifies the internal radial clearance group (CN - Normal clearance). |
| 2 | Indicates specific design features or internal geometry optimized for enhanced performance. |
1203 C/2 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball arrangement creates a robust support structure that delivers superior stiffness and can handle substantial radial dynamic loads up to 1989 lbf. This design ensures stable operation under varying load conditions.
Optimized Cage Design: Featuring a nylon cage, this bearing achieves reduced friction and excellent performance at limiting speeds of 24,000 rpm. The cage provides secure ball guidance while contributing to smooth, quiet operation.
Precision Manufacturing: Manufactured with tight dimensional tolerances (bore: -0.008mm to 0, outside diameter: -0.011mm to 0) and normal radial internal clearance (CN), ensuring consistent performance and easy installation in precision applications.
Material Excellence: Constructed from high-quality chrome steel for both rings and balls, providing excellent wear resistance, durability, and consistent performance across the specified temperature range.
