1307 C/3 Bearing Product Overview & Core Advantages
The 1307 C/3 is a double row angular contact ball bearing engineered for demanding applications requiring high precision and reliability. This metric bearing features an open design and is capable of accommodating combined loads, including significant radial loads and moderate axial loads in both directions. Its compact double row construction provides high rigidity and rotational accuracy, making it an ideal solution for high-performance machinery where space is at a premium and operational stability is critical.
1307 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1307 | Standard bearing series designation, indicating the basic dimensions (35mm bore, 80mm OD, 21mm width). |
| C | Denotes a specific internal design with a 15-degree contact angle, optimized for combined load capacity. |
| 3 | Specifies the CN radial internal clearance group (Normal clearance), suitable for most common operating conditions. |
1307 C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design, with its optimized raceway geometry and 15-degree contact angle, provides superior rigidity and enables the bearing to support substantial radial dynamic loads (5962 lbf) and two-directional axial loads simultaneously.
- Precision & Speed: Manufactured with tight dimensional tolerances on the bore diameter and outside diameter, this precision bearing ensures smooth operation. The lightweight nylon cage contributes to lower friction and enables a high limiting speed of 11,000 rpm, making it suitable for high-speed applications.
- Material & Durability: Constructed from high-grade chrome steel for both rings and balls, the bearing offers excellent wear resistance and long service life. The open seal type allows for optimal lubrication management in controlled environments.
- Standardized Internal Clearance: The C3/CN radial internal clearance is ideal for applications with moderate operational temperature variations, ensuring consistent performance.
1307 C/3 Bearing Typical Application Areas
This versatile double row angular contact ball bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Precision Agricultural Machinery
- Various machinery requiring robust support for combination loads.
