3314 A Bearing Product Overview & Core Advantages
The 3314 A is a precision double row angular contact ball bearing designed for applications requiring exceptional rigidity and the ability to handle combined loads. This metric bearing features a P6 (ABEC-3) tolerance class, ensuring high running accuracy. Its double row design provides superior high rigidity and stability compared to single row bearings, making it ideal for high-precision and high-reliability machinery where precise shaft positioning is critical under complex loading conditions.
3314 A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| 3314 | Standard bore diameter (70 mm), outside diameter (150 mm), and width (63.5 mm) dimensions. |
| A | Signifies a 30° contact angle, optimized for carrying significant axial loads in one direction while supporting radial loads. |
3314 A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides a robust, compact solution that offers high radial and axial stiffness. This design enables the bearing to effectively support combined radial and axial loads simultaneously.
- Precision Performance: Manufactured to a P6 tolerance class, this bearing guarantees precise internal geometry and smooth, quiet operation, which is essential for high-speed and high-accuracy applications.
- Optimized Material Selection: The combination of chrome steel rings and balls with a stainless steel cage ensures durability, corrosion resistance, and reliable performance at the specified limiting speed of 4,300 rpm.
- Pre-lubricated & Ready-to-Use: The bearing comes lubricated from the factory, simplifying installation and providing immediate operational readiness within its designated temperature range.
3314 A Bearing Typical Application Areas
This double row angular contact ball bearing is engineered for demanding sectors, including:
- Machine Tool Spindles
- Industrial Gearboxes
- Precision Agricultural Machinery
- Pumps and Compressors
- Heavy-duty industrial applications requiring robust support for combination loads.
