3304 A-2Z Bearing Product Overview & Core Advantages
The 3304 A-2Z is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This precision bearing is engineered to accommodate combined loads—simultaneously handling significant radial loads and axial loads in both directions. Its compact design, featuring integral shields (2Z) and pre-lubrication, ensures high reliability and long service life in demanding environments. Manufactured to P6 (ABEC-3) tolerance class, it guarantees excellent running accuracy, making it an ideal component for high-performance machinery.
3304 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| 3304 | Basic bearing series number, defining the standard bearing dimensions (20mm bore, 52mm OD, 22.2mm width). |
| A | Denotes a 30° contact angle, optimized for carrying higher axial loads. |
| 2Z | Signifies bearings with shields on both sides. This provides effective protection against contaminant ingress while being suitable for high-speed applications. |
3304 A-2Z Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to support substantial combined radial and axial loads from both directions, ensuring stable shaft positioning.
- Optimized for Speed: The combination of a stainless steel cage and effective sealing allows for a high limiting speed of 13,000 rpm, making it a capable high-speed bearing.
- Enhanced Service Life & Reliability: The shields (2Z) retain the factory-applied lubricant and protect the internal components from dust and debris, contributing to a maintenance-free, long operational life.
- Precision Performance: Manufactured to a P6 tolerance class with a narrow bore diameter tolerance, this bearing ensures precise running and minimal vibration.
3304 A-2Z Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial applications where precision, rigidity, and reliability are paramount. Key sectors include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Pumps and Compressors
