Product Overview: The 3309 Double-Row Angular Contact Ball Bearing
The 3309 bearing is a high-performance component from our 3300 Series of Angular Contact Ball Bearings. With dimensions of 45x100x39.7mm, this bearing is engineered with two rows of balls set back-to-back. This configuration allows it to accommodate combined (radial and axial) loads in both directions, providing a high degree of stiffness in a compact, space-saving design. It functions similarly to two single-row angular contact ball bearings but requires less axial space, simplifying assembly and reducing component count.
Manufactured to precise industry standards, the 3309 bearing is an excellent choice for applications requiring rigid shaft support and the ability to manage complex load conditions. Its robust construction ensures reliability and a long service life in demanding industrial environments.

Features of the 3309 Bearing
- Double-Row Design: Provides high load-carrying capacity and can accommodate combined loads in both axial directions.
- High Rigidity: The back-to-back arrangement of the two rows offers excellent stiffness, ideal for applications where shaft deflection must be minimized.
- Space-Saving: Replaces the need for two separate single-row bearings, resulting in a more compact and economical assembly.
- Combined Load Capability: Expertly manages both radial and axial forces simultaneously.
- Durable Construction: Made from high-quality, through-hardened bearing steel for superior durability and wear resistance.
- Precision Engineering: Manufactured to tight tolerances for smooth, low-friction operation and consistent performance.
Applications of 3309 Bearings
- Industrial Pumps: Provides rigid support for pump shafts, handling the combined loads typical in fluid handling systems.
- Compressors: Used in various types of compressors to support rotating components under heavy loads.
- Gearboxes and Transmissions: Offers the stiffness required to maintain precise gear meshing and efficient power transmission.
- Machine Tool Spindles: Ensures the high rotational accuracy and rigidity needed for precision cutting and milling operations.
- Hoisting Equipment: Suitable for use in cranes, winches, and other lifting machinery where combined loads are prevalent.
- Agricultural Machinery: Employed in equipment like combines and balers that operate under harsh conditions and variable loads.
- Ventilation and Fan Systems: Supports fan shafts, providing stable rotation and managing both radial and axial forces.
Benefits of Using the 3309 Bearing
- Enhanced Rotational Accuracy: The high stiffness of the double-row design minimizes shaft movement, leading to more precise operation.
- Simplified Mounting: Easier and faster to install than a paired set of two single-row bearings, reducing assembly time and potential for error.
- Improved Machine Reliability: Its ability to handle complex load scenarios reduces stress on the shaft and surrounding components, extending machine life.
- Reduced Maintenance: The robust, integrated design is less prone to failure, lowering maintenance frequency and associated costs.
- Cost-Effective Solution: Offers the performance of two bearings in a single, more affordable unit.
- Versatile Performance: Suitable for a wide array of industrial applications, making it a flexible and valuable component.
