1313C3 Bearing Product Overview & Core Advantages
The 1313C3 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing is engineered to accommodate combined loads—simultaneously handling significant radial loads and axial loads in both directions. Its compact, double-row design provides superior high rigidity and rotational accuracy. Manufactured with a C3 radial internal clearance, it is ideally suited for applications with elevated operational temperatures or where interference fits are used, ensuring reliable performance and extended service life.
1313C3 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 | Specifies a radial internal clearance greater than the Normal (CN) group. This is optimal for applications involving thermal expansion or heavy interference fits. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for higher limiting speeds and facilitating custom re-lubrication schemes if required. |
1313C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides a robust, compact solution that offers significantly higher rigidity and greater radial dynamic load rating (14,625 lbf) compared to single-row bearings, making it ideal for withstanding combined loads.
- Optimized for High-Speed Operation: Featuring a lightweight Nylon cage, this bearing minimizes centrifugal forces and friction, contributing to its high limiting speed of 6,000 rpm. The open design further enhances its potential as a high-speed bearing.
- Precision Engineering: Manufactured from high-grade Chrome Steel for both rings and balls, the bearing ensures consistent performance, high durability, and long-term dimensional stability under load.
- Pre-Lubricated & Ready for Use: Supplied with initial lubrication, the bearing is ready for immediate installation, reducing setup time and ensuring smooth initial operation.
1313C3 Bearing Typical Application Areas
This versatile double row angular contact ball bearing is commonly specified in:
- Industrial Gearboxes and Transmissions
- Pumps and Compressors
- Material Handling Equipment
- Electric Motors requiring high rigidity
- Agricultural and Construction Machinery
