1306 C/3 Bearing Product Overview & Core Advantages
The 1306 C/3 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design without seals, allowing for optimal lubrication management. Its primary advantage lies in its ability to accommodate significant radial loads while maintaining stable operation. With its compact cross-section and high rigidity due to the double row construction, it is an ideal choice for machinery where space is limited and demanding performance is required.
1306 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Basic bearing designation indicating bore diameter (30mm) and size series. |
| C | Specifies the internal radial clearance group. "C" corresponds to a clearance greater than standard CN group. |
| 3 | Indicates the tolerance class for dimensional accuracy and running precision. |
1306 C/3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing design provides superior rigidity and enables the bearing to support substantial radial dynamic load ratings of up to 5062 lbf. This makes it exceptionally robust for applications with heavy loads.
Optimized for Precision: Manufactured with a cylindrical bore and tight dimensional tolerances, it ensures precise shaft fitment and reliable rotational accuracy. The nylon cage contributes to smooth operation, reduced friction, and is suitable for high-speed applications.
High-Speed Performance: With a limiting speed of 13,000 rpm and a lubricated design, this bearing is engineered for demanding, high-velocity environments. The specified CN radial internal clearance is optimized for a wide range of operational conditions.
Material & Compliance: Constructed from high-grade chrome steel for both rings and balls, it offers excellent durability and wear resistance. The bearing is compliant with ROHS and REACH regulations, ensuring it meets modern environmental and safety standards.
1306 C/3 Bearing Typical Application Areas
The 1306 C/3 is widely used in various industrial sectors due to its robust design and high-performance characteristics. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Pumps and Compressors
