Product Overview: The 3312 Double Row Angular Contact Ball Bearing
The 3312 bearing is a high-capacity component from our 3300 Series of Angular Contact Ball Bearings. With dimensions of 60x130x54mm, this bearing features two rows of balls arranged back-to-back, making it functionally equivalent to two single-row angular contact ball bearings. This configuration provides exceptional rigidity and allows the bearing to accommodate combined radial and axial loads in both directions, as well as tilting moments. It is an ideal solution for applications where a compact, rigid, and high-capacity bearing arrangement is required.
As a leading supplier of industrial bearings, we ensure our 3312 bearings are manufactured to precise industry standards, delivering reliable performance and an extended service life in demanding operational environments. This bearing is a cornerstone component in a wide variety of heavy-duty machinery where dependable rotational support is critical. Explore our full range of angular contact ball bearings for your specific industrial needs.
Key Features of the 3312 Bearing
- Double Row Design: Provides a significantly higher load-carrying capacity compared to single-row bearings of similar dimensions.
- Combined Load Capability: Engineered to simultaneously support both radial and axial loads in either direction.
- High Rotational Accuracy: The back-to-back arrangement ensures high running accuracy and operational stiffness.
- Excellent Rigidity: Offers strong resistance to tilting and misalignment, making it suitable for applications requiring precise shaft guidance.
- Space-Saving: Delivers the performance of two single-row bearings in a more compact, single-unit design.
- Durable Construction: Manufactured from high-quality bearing steel for superior wear resistance and longevity.
Common Applications
- Industrial Pumps: Provides rigid support for pump shafts, handling the combined loads typical in fluid handling systems.
- Compressors: Used in reciprocating and screw compressors to support rotating components under heavy loads.
- Gearboxes and Reducers: Ideal for supporting gear shafts, ensuring precise meshing and efficient power transmission.
- Machine Tool Spindles: Offers the high rigidity required for precision cutting and milling operations.
- Hoists and Cranes: Supports lifting mechanisms, providing reliable performance under heavy and variable loads.
- Agricultural Machinery: Suitable for use in demanding equipment like balers and combine harvesters.
- Ventilation and Fan Systems: Ensures stable and smooth operation of industrial fans and blowers.
Benefits of Using the 3312 Bearing
- Enhanced Machine Performance: The high rigidity minimizes shaft deflection, leading to improved operational precision and efficiency.
- Increased Reliability: Capable of handling complex load conditions, reducing the risk of premature failure and costly downtime.
- Simplified Assembly: Easier and quicker to mount than a matched pair of single-row angular contact ball bearings, reducing installation costs.
- Compact Design Solution: Allows for more compact and lightweight machinery design without sacrificing performance.
- Reduced Maintenance: Robust construction and the ability to handle combined loads effectively contribute to a longer service life and lower maintenance requirements.
- Cost-Effective: Often provides a more economical solution than using two separate bearings, considering both component and assembly costs.
