1320 C/3 Bearing Product Overview & Core Advantages
The 1320 C/3 is a double row angular contact ball bearing designed for applications requiring high load capacity and rigidity. This precision bearing excels at simultaneously handling significant radial loads and moderate axial loads in both directions, making it ideal for demanding industrial environments. Its open design, combined with optimized internal geometry and CN radial internal clearance, ensures reliable performance in high-speed applications up to 4,000 rpm. Manufactured from chrome steel with a stainless steel cage, it offers excellent durability and corrosion resistance.
1320 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Standard bearing series designation indicating bearing dimensions (100 mm bore, 215 mm OD, 47 mm width) |
| C | Designates optimized internal geometry and contact angle for enhanced load capacity |
| 3 | Indicates CN radial internal clearance - standard clearance for normal operating conditions |
1320 C/3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and can handle combined loads effectively, with a dynamic load rating of 32,175 lbf and static load rating of 12,825 lbf.
Optimized Internal Geometry: The C-design internal construction ensures optimal stress distribution and enhanced bearing performance under various loading conditions.
High-Speed Capability: The stainless steel cage and precision manufacturing enable reliable operation at limiting speeds up to 4,000 rpm, making it suitable for high-speed applications.
