Product Overview: The 3308 Double-Row Angular Contact Ball Bearing
The 3308 bearing is a high-capacity component from our 3300 Series of Angular Contact Ball Bearings. With dimensions of 40x90x36.5mm, this bearing is engineered with two rows of balls arranged back-to-back. This design allows it to accommodate high radial loads and axial loads in both directions, making it an excellent choice for applications requiring rigid support and the ability to handle combined loads and tilting moments. Its compact structure provides the functionality of two single-row angular contact bearings but within a smaller axial space.
As a specialist supplier of industrial bearings, we ensure our 3308 bearings are manufactured to precise industry standards. This guarantees reliable performance, durability, and a long operational lifespan, even in demanding industrial environments. The 3308 is a versatile solution for a wide range of machinery where robust and reliable rotational support is critical.
Features of the 3308 Bearing
- Double-Row Design: Provides high load-carrying capacity for both radial and axial forces in both directions.
- Combined Load Capability: Excellently suited for applications with simultaneous radial and axial loads.
- High Rigidity: Offers strong support against tilting and moments, ensuring stable shaft operation.
- Compact and Space-Saving: Delivers the performance of two single-row bearings in a narrower, more compact unit.
- 30° Contact Angle: The standard contact angle provides a balanced capacity for radial and axial loads.
- Durable Construction: Manufactured from high-quality bearing steel for superior wear resistance and longevity.
Applications of 3308 Bearings
- Industrial Pumps: Provides rigid support for pump shafts, handling high pressures and speeds.
- Compressors: Used in various types of compressors to support rotating components under heavy loads.
- Gearboxes: Ideal for transmission systems where combined loads and shaft rigidity are essential.
- Machine Tool Spindles: Ensures precision and stability in high-speed cutting and grinding applications.
- Hoists and Lifting Equipment: Supports pulleys and rotating shafts in cranes and other lifting machinery.
- Agricultural Machinery: Employed in demanding equipment like combines and balers that experience complex loads.
- Electric Motors: Offers robust support for motor shafts, especially in heavy-duty industrial motors.
Benefits of Using the 3308 Bearing
- Enhanced Load Capacity: The double-row configuration significantly increases the bearing's ability to handle heavy loads compared to single-row bearings.
- Improved Machine Performance: High rigidity minimizes shaft deflection, leading to greater operational accuracy and efficiency.
- Extended Service Life: Capable of withstanding complex load conditions, reducing wear and extending the lifespan of machinery.
- Simplified Assembly: Using one double-row bearing instead of a matched pair of single-row bearings simplifies design and installation.
- Reduced Maintenance: Robust construction and high performance lead to fewer failures and lower maintenance requirements.
- Operational Versatility: Suitable for a wide array of applications, making it a flexible component for various industrial needs.
