3210 ATN9 Bearing Product Overview & Core Advantages
The 3210 ATN9 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 handling significant radial loads and axial loads in both directions. Its compact design, featuring a 50 mm bore, 90 mm outside diameter, and 30.2 mm width, offers a space-saving solution. Manufactured to a P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy, making it ideal for high-performance mechanical systems demanding high rigidity and stable operation.
Model Code Breakdown
- 3210: Basic model number denoting a double row angular contact ball bearing with a 50 mm bore and 90 mm outside diameter.
- A: Signifies a 30-degree contact angle, optimized for carrying higher axial loads.
- TN9: Indicates the cage material and type. The cage is made from Nylon (Polyamide), which is lightweight, contributes to low friction and quiet operation, and is suitable for high-speed applications.
3210 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to support substantial combined loads effectively. The specified contact angle (A-design) further enhances its axial load carrying capacity.
High-Speed Performance: The lightweight Nylon (TN9) cage reduces centrifugal forces, allowing for a high limiting speed of 7,000 rpm. The bearing comes pre-lubricated, ensuring immediate readiness and smooth operation at high velocities.
Precision and Durability: Manufactured from chrome steel for both rings and balls, the bearing offers high strength and wear resistance. The adherence to P6 tolerance guarantees precise dimensions and reliable performance in demanding applications.
Operational Readiness: Being pre-lubricated, the bearing is ready for installation and offers stable performance across a wide temperature range from -30°C to 110°C.
3210 ATN9 Bearing Typical Application Areas
The 3210 ATN9 is suited for a variety of industrial applications where precision, speed, and reliability are paramount. Common uses include:
- Machine Tool Spindles
- Precision Gearboxes
- Industrial Pumps and Compressors
- Electric Motors
- Material Handling Equipment
