1306 C3 Bearing Product Overview & Core Advantages
The 1306 C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Its metric, open design with a cylindrical bore facilitates precise mounting and optimal performance. Engineered with chrome steel rings and balls, this bearing offers excellent durability. The specified C3 radial internal clearance makes it suitable for applications with elevated operational temperatures or where interference fits are used, ensuring consistent performance and extended service life.
1306 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Standard bearing designation indicating a double row design with a 30 mm bore diameter and 72 mm outside diameter. |
| C3 | Indicates a greater radial internal clearance than the standard CN group. This is crucial for applications involving thermal expansion, high speeds, or heavy loads. |
1306 C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support significant radial loads and moderate axial loads in both directions, making it ideal for combined load scenarios.
- Optimized Material & Cage: Components made from chrome steel ensure high wear resistance and fatigue life. The nylon cage contributes to smooth operation, lower noise, and is well-suited for high-speed applications up to the specified limiting speed.
- Operational Flexibility: The C3 clearance accommodates dimensional changes from heat generation or press-fits, preventing pre-loading and potential seizure, thereby enhancing operational reliability.
- Precision Tolerances: Tight dimensional tolerances on the bore, outside diameter, and width ensure precise shaft and housing fits, contributing to accurate rotational performance.
1306 C3 Bearing Typical Application Areas
This double row angular contact ball bearing is commonly specified in:
- Industrial Gearboxes and Transmissions
- Electric Motors and Generators
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
