1313 C3 Bearing Product Overview & Core Advantages
The 1313 C3 is a double row angular contact ball bearing designed for demanding applications requiring high load capacity and robust performance. This precision bearing excels at simultaneously handling significant combined loads, including radial forces and bidirectional axial loads, thanks to its optimized contact angle and double-row design. Its open construction allows for versatile lubrication options, while the generous C3 radial internal clearance makes it ideal for applications with thermal expansion or where interference fits are used. Engineered for high rigidity and reliable operation, it is a cornerstone component for industrial machinery.
1313 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bearing series designation, indicating the bearing dimensions (65mm bore, 140mm OD, 33mm width). |
| C3 | Indicates a greater-than-normal radial internal clearance. This is critical for applications involving thermal expansion, heavy interference fits, or where lower operational temperatures are desired. |
1313 C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide exceptional stiffness, enabling the bearing to support high radial dynamic load ratings of 14,625 lbf and manage substantial combined loads effectively.
- Optimized for Challenging Conditions: The specified C3 clearance accommodates dimensional changes from heat or press-fitting, preventing premature failure due to excessive preload and ensuring consistent performance.
- Versatile & Durable Construction: Featuring Chrome Steel rings and balls for high durability and a Nylon cage for quiet operation and reduced friction, suitable for limiting speeds up to 6,000 rpm. The open design allows for custom lubrication schemes to match specific operational needs.
