3204 A Bearing Product Overview & Core Advantages
The 3204 A is a double row angular contact ball bearing designed for applications requiring high precision and reliability. Engineered to simultaneously handle combined loads (radial and bidirectional axial loads), this bearing offers exceptional rigidity and rotational accuracy. Its compact design and P6 (ABEC-3) tolerance class make it ideal for high-performance machinery where space constraints and precision are critical. The bearing comes pre-lubricated for immediate use and features an open design optimized for controlled environments.
3204 A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 3204 | Standard bore diameter (20mm) & series designation | Defines core bearing dimensions |
| A | 30° contact angle | Optimized for high axial load capacity |
3204 A Bearing Structural Features & Performance Benefits
- High Rigidity: The double row design provides superior stiffness compared to single row bearings, minimizing deflection under combined loads
- Enhanced Load Capacity: Engineered to handle significant radial loads and bidirectional axial loads simultaneously
- Precision Performance: Stainless steel cage ensures stable operation at high speeds, contributing to the limiting speed of 14,000 rpm
- Optimized Geometry: 28mm distance from side face to load point provides optimal load distribution and moment resistance
- Premium Materials: Chrome steel rings and balls with stainless steel cage deliver durability and corrosion resistance
3204 A Bearing Typical Application Areas
- Machine Tool Spindles - Where high precision and rigidity are essential
- Precision Gearboxes - For handling combined loads in compact spaces
- Industrial Pumps & Compressors - Demanding high-speed operation and reliability
- Medical Equipment - Requiring precise motion control and clean operation
- Robotics & Automation - Applications needing high rigidity and accuracy
