1304C3 Bearing Product Overview & Core Advantages
The 1304C3 is a double row angular contact ball bearing designed for applications demanding high rigidity and reliable performance under combined loads. This precision bearing efficiently accommodates significant radial loads and axial loads in both directions, making it an ideal solution for compact, high-performance assemblies. Its open design, combined with a specified C3 radial internal clearance, ensures optimal operation in applications with thermal expansion or where interference fits are used.
1304C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1304 | Standard bearing series designation, indicating a 20mm bore diameter and 52mm outside diameter. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy interference fits, or where operational heat generation is expected. |
1304C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to support substantial combined loads (radial and bidirectional axial loads) simultaneously.
- Optimized for Demanding Conditions: The specified C3 clearance prevents pre-loading and potential seizure in applications prone to thermal expansion or where tight shaft and housing fits are required.
- High-Speed Capability: The lightweight Nylon cage ensures smooth operation and low friction, contributing to a high limiting speed of 18,000 rpm.
- Durability and Precision: Manufactured from Chrome Steel for both rings and balls, this bearing offers high wear resistance and long service life, maintaining precision under demanding conditions.
1304C3 Bearing Typical Application Areas
This bearing is well-suited for a wide range of industrial machinery, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
