1320-K C/3 Bearing Product Overview & Core Advantages
The 1320-K C/3 is a metric double row angular contact ball bearing engineered for high-performance applications requiring superior radial load capacity and precision operation. Featuring a tapered bore (1:12) design, this bearing ensures secure mounting on tapered shafts while maintaining exceptional rotational accuracy. Its double row construction provides enhanced rigidity and load distribution, making it ideal for machinery demanding high reliability under substantial radial forces. Manufactured from premium chrome steel components and equipped with stainless steel cage, it delivers consistent performance across a wide temperature range (-30° to 110°C) with CN radial internal clearance optimized for most industrial applications.
1320-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| K | Tapered Bore (1:12) | Enables precise interference fit on tapered shafts for secure mounting |
| C/3 | Radial Internal Clearance Group C3 | Provides slightly greater than normal clearance for thermal expansion in high-speed applications |
1320-K C/3 Bearing Structural Features & Performance Benefits
Enhanced Load Capacity: The double row ball bearing configuration delivers outstanding radial dynamic load rating of 32,175 lbf and static load rating of 12,825 lbf, enabling reliable operation under heavy radial loads.
Precision Engineering: With tight dimensional tolerances (bore: -0.02mm to 0, OD: -0.03mm to 0) and CN clearance group, this bearing ensures smooth rotation and minimal vibration in precision applications.
High-Speed Capability: The stainless steel cage and optimized internal geometry support limiting speeds up to 4,000 rpm, making it suitable for demanding rotational applications.
Robust Construction: Manufactured from chrome steel rings and balls with proper chamfer dimensions (3mm) and specified shoulder diameters (inner: 136mm, outer: 181.9mm) for optimal load transfer and installation.
