3314 A-2Z Bearing Product Overview & Core Advantages
The 3314 A-2Z is a double row angular contact ball bearing engineered for applications requiring high rigidity and the ability to handle combined loads. Its compact design integrates two rows of balls, enabling it to support significant radial loads and bidirectional axial loads simultaneously. Manufactured to a P6 (ABEC-3) tolerance class, this precision bearing ensures reliable performance in high-accuracy and demanding operational environments. The inclusion of shields and factory-applied lubrication contributes to its long service life and low-maintenance characteristics.
Model Code Breakdown
- 3314: Basic model number, indicating a metric series double row angular contact ball bearing with a 70 mm bore and 150 mm outside diameter.
- A: Signifies a specific internal design and contact angle (typically 30°), optimized for combined load carrying capacity.
- 2Z: Denotes that the bearing is equipped with shields on both sides. These non-contact shields protect the internal components from coarse contaminants while minimizing friction, making it suitable for high-speed operation.
3314 A-2Z Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, making it exceptionally resistant to operational deflection. This construction allows the bearing to effectively manage substantial combined loads (radial and axial acting together).
Optimized for Speed: The standard stainless steel cage ensures stability and reduced centrifugal forces at high rotational velocities. Combined with the low-friction shields, this contributes to the bearing's impressive limiting speed of 4,300 rpm.
Enhanced Service Life & Reliability: The bearing comes pre-lubricated, facilitating immediate installation and operation. The 2Z shields effectively retain the lubricant and exclude larger particulate contaminants, promoting a long, maintenance-free service interval under standard operating conditions.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and wear resistance. Adherence to the P6 tolerance class guarantees precise bearing dimensions and running accuracy.
3314 A-2Z Bearing Typical Application Areas
The 3314 A-2Z is ideally suited for a wide range of industrial machinery where high rigidity and combined load support are critical. Common applications include:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Gearboxes and Transmission Systems
- Precision Agricultural Equipment
- Material Handling Systems
