Product Overview and Core Advantages
The 1313 C/2 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open construction, enabling it to accommodate combined loads—significant radial forces along with moderate axial loads in both directions. Its compact design, characterized by a 33 mm width relative to its 140 mm outside diameter, provides a space-saving solution without compromising performance. Manufactured from high-grade chrome steel for both rings and balls, and utilizing a durable nylon cage, this bearing delivers exceptional high rigidity and stable operation, making it ideal for demanding industrial environments.
Model Code Detailed Explanation
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bore diameter code (65 mm) and series designation. |
| C | Indicates a double row angular contact ball bearing with a 15° contact angle, optimized for combined loads. |
| 2 | Specifies the internal clearance group. In this case, it corresponds to the CN (Normal) radial internal clearance. |
Structural Features and Performance Benefits
- High Rigidity and Load Capacity: The double row design significantly increases the number of load-carrying balls, resulting in superior high rigidity and the ability to handle substantial radial dynamic load ratings of 14,625 lbf and radial static load ratings of 5,738 lbf. This makes it exceptionally capable of managing combined loads.
- Optimized for Performance: The nylon cage ensures smooth operation, reduces friction, and contributes to the bearing's suitability for high-speed applications, with a limiting speed of 6,000 rpm. The open seal type allows for optimal lubrication flow and heat dissipation.
- Precision and Durability: Manufactured from chrome steel, the bearing components offer high wear resistance and dimensional stability. The specified CN radial internal clearance provides a balance suitable for a wide range of operating conditions.
- Ready for Operation: The bearing comes lubricated from the factory and is capable of operating within a temperature range of -30°C to 110°C, ensuring immediate deployment and reliable performance.
