1204JC3 Bearing Product Overview & Core Advantages
The 1204JC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Featuring an open design and C3 radial internal clearance, this precision bearing accommodates thermal expansion during high-speed operation while maintaining stable performance. Its compact dimensions (20mm bore × 47mm OD × 14mm width) and robust construction make it ideal for space-constrained applications demanding high reliability and load capacity.
1204JC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1204 | Basic designation: 20mm bore, 47mm OD | Standard bearing dimensions for easy interchangeability |
| J | Steel cage construction | Enhanced durability and strength |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, suitable for high-speed applications |
1204JC3 Bearing Structural Features & Performance Benefits
Double Row Design: The dual ball complement arrangement provides high rigidity and superior moment load capacity compared to single row bearings, ensuring stable operation under complex loading conditions.
Load Capacity: With a dynamic load rating of 2858 lbf and static load rating of 765 lbf, this bearing effectively handles combined radial and axial loads in both directions, making it versatile for various industrial applications.
High-Speed Capability: The steel cage and optimized internal geometry enable operation at limiting speeds up to 20,000 rpm, while the C3 clearance accommodates thermal expansion during high-speed operation.
Precision Manufacturing: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.01mm to 0), ensuring consistent performance and long service life in precision applications.
