1320C3 Bearing Product Overview & Core Advantages
The 1320C3 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and operational stability. This precision bearing features an open design with a generous C3 radial internal clearance, making it exceptionally suitable for applications where thermal expansion is a consideration. Its robust construction ensures high rigidity and reliable performance under demanding conditions, offering an optimal solution for handling combined loads.
1320C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Standard bearing series designation, indicating bearing dimensions (100mm bore, 215mm OD, 47mm width). |
| C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with anticipated thermal expansion or where fit-up conditions require extra internal space. |
1320C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust chrome steel construction provide superior high rigidity, enabling the bearing to support significant radial dynamic load ratings of 32,175 lbf.
- Optimized for Thermal Conditions: The specified C3 radial internal clearance allows for shaft expansion under operational heat, preventing pre-loading and potential seizure, thereby enhancing service life.
- Durable Cage Design: The stainless steel cage ensures high strength and corrosion resistance, contributing to stable operation and longevity.
- Pre-Lubricated for Immediate Use: The bearing is supplied lubricated, facilitating easy installation and providing initial protection against wear.
1320C3 Bearing Typical Application Areas
This bearing is ideally suited for a range of industrial machinery where robustness and accommodation for thermal effects are paramount. Key applications include:
- Industrial Gearboxes and Transmissions
- Vibrating Screens and Conveyors
- Agricultural Machinery
- Electric Motors and Generators
- Material Handling Equipment
