3210 A Bearing Product Overview & Core Advantages
The 3210 A is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing is engineered to accommodate combined loads, simultaneously supporting significant radial loads and bidirectional axial loads. Its compact design, featuring optimized bearing dimensions (50 mm bore, 90 mm OD, 30.2 mm width), provides a robust and space-efficient solution for demanding industrial environments. Manufactured to P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and consistent performance.
3210 A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Indicates an optimized internal design with a 30° contact angle, providing superior axial load capacity and high rigidity. |
| (No Seal Suffix) | The bearing is supplied in an Open configuration, allowing for custom lubrication schemes and facilitating high-speed operation. |
3210 A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and 30° contact angle create an exceptionally rigid structure capable of handling heavy combined loads (Radial dynamic: 11475 lbf, Static: 9562 lbf). The defined distance from side face to load point (52 mm) ensures optimal force distribution.
- High-Speed Performance: The stainless steel cage and open seal type contribute to a high limiting speed of 7,000 rpm, making it suitable for high-speed applications.
- Precision Engineering: Manufactured to P6 tolerance class with tight dimensional tolerances, this bearing guarantees smooth, low-vibration operation essential for precision machinery.
- Durability & Compliance: Components made from chrome steel offer excellent wear resistance and fatigue life. The bearing is pre-lubricated and compliant with ROHS and REACH standards.
3210 A Bearing Typical Application Areas
The 3210 A is ideally suited for a wide range of demanding applications across various industries, including:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Precision Gearboxes
- Material Handling Equipment
- Agricultural Machinery
