1204 C3 Bearing Product Overview & Core Advantages
The 1204 C3 is a double row ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling significant radial loads while maintaining operational stability. Its open construction allows for versatile lubrication options, and the specified C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. Engineered with a nylon cage, it offers smooth operation and is an ideal choice for scenarios requiring high reliability and consistent performance.
1204 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1204 | Standard bearing designation indicating a 20 mm bore diameter and 47 mm outside diameter. |
| C3 | Specifies a greater radial internal clearance than the standard C0 group. This is critical for applications involving thermal expansion, high speeds, or heavy loads. |
1204 C3 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The double row construction provides superior radial load rating (2858 lbf dynamic) and increased rigidity compared to single row bearings, ensuring stable support for shafts under heavy loads.
- Optimized for Demanding Conditions: The specified C3 clearance accommodates dimensional changes from heat generation or press-fits, preventing premature failure due to binding and ensuring consistent performance.
- Smooth High-Speed Operation: The lightweight nylon cage minimizes friction and inertial forces, contributing to the bearing's ability to operate effectively at its limiting speed of 20,000 rpm.
- Material Integrity: Manufactured from high-grade chrome steel for both rings and balls, the bearing ensures excellent durability, wear resistance, and a long operational lifespan.
1204 C3 Bearing Typical Application Areas
This bearing is commonly specified in industrial machinery where high radial load capacity and operational reliability are paramount. Key sectors include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Agricultural Machinery and Conveyor Systems
- General machinery requiring robust bearing dimensions (20x47x14 mm) and a C3 clearance fit.
