3219 A Bearing Product Overview & Core Advantages
The 3219 A is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously supporting substantial combined loads, including radial loads and bidirectional axial loads. Its double-row design provides exceptional high rigidity, making it ideal for demanding operational conditions. Manufactured to a P6 (ABEC-3) tolerance class, it ensures consistent performance and accuracy in high-speed and precision machinery.
3219 A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Indicates a 30° contact angle, optimized for carrying significant axial loads. |
| Open | No seals or shields, allowing for higher speeds and enabling custom lubrication regimes. |
3219 A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized 30° contact angle provide superior high rigidity and enable the bearing to handle heavy combined loads (radial and bidirectional axial) effectively.
- High-Speed Performance: The standard stainless steel cage ensures stability and reduced friction at the limiting speed of 3,400 rpm.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, and built to P6 tolerance, this bearing guarantees long service life and operational accuracy.
- Pre-lubricated: Comes with initial lubrication suitable for a wide temperature range of -30°C to 110°C, ensuring immediate operational readiness.
3219 A Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Gearboxes and Power Transmission Systems
- Precision Industrial Machinery
