1204J Bearing Product Overview & Core Advantages
The 1204J metric ball bearing is a double row angular contact ball bearing designed for exceptional performance in demanding applications. Its double row construction provides superior high rigidity and enables it to withstand significant combined loads, including radial and bidirectional axial forces. Manufactured with precision tolerances and high-grade materials, this bearing is engineered for high reliability and stable operation in compact spaces where robust support is critical.
1204J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1204 | Standard bore diameter code (20 mm) and dimension series. |
| J | Indicates a specific internal design and CN radial internal clearance (Normal group). |
Key Feature: The "J" suffix is crucial for applications requiring a standard, versatile internal fit, ensuring optimal performance under normal operating conditions.
1204J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design features two rows of balls, significantly increasing contact angles and providing exceptional resistance to deformation under combined loads. This results in superior high rigidity for precise shaft positioning.
- Optimized for Performance: The steel cage ensures stability at the specified limiting speed of 20,000 rpm. The open seal type allows for easy re-lubrication, which is essential for maintaining performance in high-speed or continuous operation scenarios.
- Precision Engineering: Manufactured with tight dimensional tolerances on the bore diameter and outside diameter, this bearing guarantees consistent performance and ease of installation.
- Material Integrity: Constructed from chrome steel for both rings and balls, the bearing offers high durability, wear resistance, and a long operational lifespan within its specified temperature range of -30°C to 110°C.
1204J Bearing Typical Application Areas
The 1204J bearing is ideally suited for a wide range of industrial machinery requiring robust support and high precision, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
Its ability to handle combined loads and provide high rigidity makes it a reliable component in applications where shaft deflection must be minimized.
