Product Overview: The 3311 Double-Row Angular Contact Ball Bearing
The 3311 bearing is a high-capacity component from our 3300 Series, engineered to handle complex load conditions. As a type of Angular Contact Ball Bearing, it features a double-row design equivalent to two single-row angular contact bearings arranged back-to-back. This configuration allows it to accommodate heavy radial loads and axial loads in both directions, providing a high degree of stiffness in a compact design. With its standard dimensions of 55x120x49.2mm, the 3311 is a robust solution for a wide range of industrial applications requiring rigid shaft support and reliable performance under combined loads.
Key Features of the 3311 Bearing
- Double-Row Construction: Provides the functionality of two single-row bearings in one, saving space and simplifying assembly.
- Bi-Directional Axial Load Capacity: Capable of accommodating axial loads in both directions, making it highly versatile.
- High Radial Load Support: Designed to withstand significant radial forces, ensuring stability in demanding applications.
- Increased Rigidity: The back-to-back arrangement offers high stiffness, which is critical for applications requiring precise shaft location.
- Durable Steel Cage: Equipped with a robust cage to maintain ball spacing and ensure smooth, reliable operation.
- Standardized Dimensions: Manufactured to industry-standard dimensions for easy interchangeability and integration into existing designs.
Common Applications
- Industrial Pumps and Compressors: Provides rigid support for shafts, ensuring efficient operation under high pressure.
- Gearboxes and Transmissions: Ideal for supporting gears and shafts, handling the combined loads typical in these systems.
- Machine Tool Spindles: Offers the high rigidity required for precision cutting and machining operations.
- Agricultural Machinery: Used in equipment like tillers and harvesters where components are subjected to heavy and varying loads.
- Material Handling Equipment: Suitable for conveyor systems, hoists, and other machinery requiring robust bearing support.
- Industrial Fans and Blowers: Ensures stable rotation of fan shafts, even under significant aerodynamic loads.
- Electric Motors: Provides reliable support for motor shafts, handling both radial and axial forces.
Benefits of Using the 3311 Bearing
- Enhanced Load Handling: Superior capacity for combined radial and axial loads compared to single-row or deep groove ball bearings.
- Space-Saving Design: Combines two bearings into one unit, reducing the required axial space and overall component count.
- Improved System Rigidity: Contributes to greater overall machine stiffness, enhancing performance and accuracy.
- Extended Service Life: Robust construction and high load capacity lead to a longer operational lifespan and reduced downtime.
- Simplified Mounting: As a single unit, it is often easier to install than a matched pair of single-row bearings.
- Versatile Performance: Its ability to handle various load types makes it a flexible solution for a multitude of industrial applications.
