3316 A Bearing Product Overview & Core Advantages
The 3316 A is a double row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. This precision bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and bidirectional axial loads. Its compact, double-row construction provides superior high rigidity and rotational accuracy, making it an ideal solution for demanding industrial machinery. Manufactured to a P6 (ABEC-3) tolerance class and pre-lubricated for immediate use, it delivers consistent performance and long service life.
3316 A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Indicates an optimized internal design with a 30° contact angle, providing enhanced axial load capacity and rigidity. |
| Open (No Seal Suffix) | The bearing is supplied without seals or shields, allowing for higher limiting speeds and making it suitable for applications where external sealing is provided or where re-lubrication is part of the maintenance plan. |
3316 A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide exceptional stiffness, enabling stable operation under heavy combined loads. The optimized contact angle ensures reliable performance for both radial and bidirectional axial forces.
- Precision & Speed: Built to a P6 tolerance class, this bearing guarantees high running accuracy. The stainless steel cage ensures smooth operation and contributes to a high limiting speed of 3,800 rpm, making it suitable for high-speed applications.
- Material & Durability: Manufactured from chrome steel for rings and balls, the bearing offers high fatigue life and wear resistance. The standard pre-lubrication facilitates immediate start-up and initial operation.
3316 A Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery where precision, rigidity, and reliability are paramount. Key applications include:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Gearboxes and Power Transmission Systems
- Precision Industrial Machinery
