1308 C3 Bearing Product Overview & Core Advantages
The 1308 C3 is a double row angular contact ball bearing engineered for applications demanding high rigidity and the capacity to handle combined loads. Its metric design and open construction make it an ideal precision bearing for robust machinery. A key feature is its specified C3 radial internal clearance, which accommodates thermal expansion in high-speed or thermally unstable environments, ensuring reliable performance and extended service life.
1308 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 1308 | Standard bearing designation indicating bore diameter (40 mm), outside diameter (90 mm), and width (23 mm). | Defines the standard bearing dimensions for easy identification and interchangeability. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Prevents preload and binding under operational heat, crucial for high-speed applications and preventing premature failure. |
1308 C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior rigidity and enables the bearing to support significant radial loads and moderate axial loads in both directions, making it suitable for combined load conditions.
- Optimized for Speed: The lightweight Nylon cage ensures stable operation and low friction, contributing to the high limiting speed of 9,500 rpm. The open design allows for efficient lubrication management.
- Precision & Durability: Manufactured from hardened Chrome Steel for both rings and balls, this bearing offers high durability, wear resistance, and consistent performance in precision applications.
- Operational Flexibility: The C3 clearance and standard lubrication provide operational flexibility across a wide temperature range from -30°C to 110°C.
1308 C3 Bearing Typical Application Areas
This bearing is commonly specified in industries and equipment where reliability under demanding conditions is paramount. Key applications include:
- Industrial Gearboxes and Power Transmission Systems
- Electric Motors and Generators
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring robust support
