Product Overview: The 3307 Double-Row Angular Contact Ball Bearing
The 3307 bearing is a high-capacity, double-row angular contact ball bearing designed to handle combined radial and axial loads in both directions. With dimensions of 35x80x34.9mm, this bearing is part of our robust 3300 Series and provides a rigid and compact solution for demanding industrial applications. Its back-to-back arrangement of two single-row angular contact bearings within a single unit offers exceptional stiffness and a high moment-load capacity, making it a superior choice where space is limited and high performance is required.
As a leading supplier of Angular Contact Ball Bearings, we ensure our 3307 bearings meet stringent industry standards for quality and precision. This design is particularly effective in applications requiring precise shaft positioning and the ability to accommodate tilting moments, such as in pumps, industrial gearboxes, and compressors.
Key Features of the 3307 Bearing
- Double-Row Design: Offers the functionality of two single-row bearings in a back-to-back arrangement, providing high load capacity in a compact space.
- Bidirectional Axial Load Support: Capable of accommodating heavy axial loads in both directions, in addition to radial loads.
- High Rigidity: The design provides a very stiff bearing arrangement, essential for applications requiring high running accuracy.
- Standard 30° Contact Angle: Optimized for handling significant combined loads.
- Precision Manufacturing: Engineered from high-quality bearing steel to ensure durability, longevity, and consistent performance under load.
- Space-Saving: Its compact width makes it an excellent alternative to using two separate single-row bearings.
Common Applications of 3307 Bearings
- Industrial Pumps: Provides robust support for pump shafts, handling the high radial and axial forces common in fluid transfer systems.
- Compressors: Used in various types of compressors to support rotating components with high rigidity.
- Gearboxes and Reducers: Ideal for gear shafts where precise positioning and accommodation of tilting moments are critical.
- Machine Tool Spindles: Offers the stiffness required for high-precision cutting and grinding operations.
- Hoisting Equipment and Cranes: Suitable for sheaves and lifting mechanisms that experience heavy, bidirectional loads.
- Agricultural Machinery: Employed in demanding equipment like tillers and harvesters where durability is essential.
- Textile Machinery: Ensures reliable and precise operation in high-speed spinning and weaving equipment.
Benefits of Using the 3307 Bearing
- Enhanced Load Capacity: Effectively manages complex load conditions, improving the reliability of the machinery.
