3319 A Bearing Product Overview & Core Advantages
The 3319 A is a double row angular contact ball bearing designed for applications requiring high precision and exceptional rigidity. This precision bearing excels at simultaneously handling combined radial and bidirectional axial loads. Manufactured to P6 (ABEC-3) tolerance class, it offers superior running accuracy and is pre-lubricated for immediate use, making it an ideal choice for high-performance machinery where reliability and high rigidity are paramount. Its compact design integrates the functionality of two single-row bearings, saving space and simplifying assembly.
3319 A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3319 | Standard bearing series designation, defining the core bearing dimensions (95mm bore, 200mm OD). |
| A | Signifies a 30-degree contact angle. This specific angle optimizes the bearing's capacity to support significant axial loads from both directions while maintaining excellent radial load capacity. |
3319 A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior stiffness, effectively resisting operational deflections. This design enables the bearing to sustain high combined loads (radial and axial) with stability.
- Optimized for Precision: Built to a P6 tolerance class, this bearing ensures minimal runout and smooth, precise rotation, which is critical for applications like machine tool spindles.
- Durable Construction: The use of chrome steel for rings and balls, combined with a stainless steel cage, ensures high durability, corrosion resistance, and reliable performance at the specified limiting speed of 3,200 rpm.
- Ready-to-Install: The bearing comes pre-lubricated, reducing initial setup time and ensuring optimal performance from the first rotation.
3319 A Bearing Typical Application Areas
This bearing is engineered for demanding environments. Key applications include:
- Machine Tool Spindles
- High-Precision Gearboxes
- Industrial Pumps and Compressors
- Precision Positioning Systems
