1320 K/C3 Bearing Product Overview & Core Advantages
The 1320 K/C3 is a double row angular contact ball bearing engineered for demanding industrial applications requiring high load capacity and robust performance. This precision bearing is designed with a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate operation. Its primary strength lies in its ability to support significant combined loads—handling substantial radial forces while accommodating axial loads in both directions. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or heavy interference fits, ensuring reliable performance under challenging conditions. This design results in a compact, high-rigidity solution ideal for high-reliability machinery.
1320 K/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1320 | Basic bearing designation | Defines the standard bearing dimensions: 100mm bore, 215mm OD, 47mm width |
| K | Tapered bore (1:12) | Enables precise mounting on tapered shaft seats for secure fit |
| C3 | Radial internal clearance greater than normal | Accommodates thermal expansion and interference fits, preventing premature failure |
1320 K/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides exceptional stiffness, enabling the bearing to withstand heavy combined loads without significant deformation. With a dynamic load rating of 32,175 lbf and static load rating of 12,825 lbf, it delivers reliable performance in demanding applications.
Optimized Construction: The nylon cage ensures smooth operation at the limiting speed of 4,000 rpm, reducing friction and heat generation. The tapered bore (K-designation) allows for precise axial positioning and secure mounting, enhancing overall system stability.
Thermal Management: The C3 clearance is specifically engineered to handle thermal expansion encountered in high-speed or high-temperature applications, maintaining optimal performance across the operating temperature range of -30°C to 110°C.
Material Excellence: Manufactured from chrome steel for both rings and balls, the bearing offers superior hardness, wear resistance, and fatigue life, ensuring long-term reliability in industrial environments.
