Product Overview: The 3306 Double-Row Angular Contact Ball Bearing
The 3306 bearing is a high-performance, double-row angular contact ball bearing designed to handle complex load conditions. As part of our robust 3300 Series, this bearing provides a compact and rigid solution for applications requiring support for both radial and axial loads in both directions. Its design is equivalent to two single-row angular contact ball bearings arranged back-to-back, offering excellent stiffness and moment-load capabilities. With dimensions of 30x72x30.2mm, the 3306 is a versatile choice for demanding industrial machinery.
As a specialist supplier of industrial mechanical parts, we ensure our 3306 bearings meet stringent quality standards for reliability and longevity. This bearing is a critical component in machinery where shaft rigidity and precise positioning are essential.

Key Features of the 3306 Bearing
- Double-Row Design: Provides high load-carrying capacity for radial and bidirectional axial loads within a compact footprint.
- High Rigidity: Offers excellent support against tilting moments, ensuring stable and precise shaft guidance.
- Fixed Contact Angle: Engineered with a non-separable design and a fixed contact angle to manage combined loads effectively.
- Back-to-Back Arrangement: The internal construction mimics a back-to-back mounting of two single-row bearings, enhancing rigidity.
- Durable Construction: Manufactured from premium-grade bearing steel for superior hardness, wear resistance, and extended service life.
- Precision Engineering: Guarantees smooth operation, reduced friction, and consistent performance under demanding conditions.
Common Applications
- Pumps and Compressors: Provides rigid support for shafts in centrifugal pumps and screw compressors, handling combined loads efficiently.
- Industrial Gearboxes: Used to support gear shafts, maintaining precise alignment and managing forces generated during operation.
- Machine Tool Spindles: Offers the high rigidity required for precision cutting and milling operations.
- Lifting Equipment: Ideal for use in hoists, winches, and cranes where combined loads and high stiffness are critical.
- Industrial Fans and Blowers: Supports rotating assemblies, ensuring stability and reliable performance under continuous operation.
- Agricultural Machinery: Suitable for demanding applications in equipment like combines and balers that experience heavy, multi-directional loads.
- Electric Motors: Used to support motor shafts, providing stability and accommodating both radial and axial forces.
Benefits of Using the 3306 Bearing
- Enhanced Load Capacity: Capable of accommodating heavy radial and axial loads in both directions simultaneously.
- Space-Saving Design: Delivers the performance of two single-row bearings in a narrower, more compact unit.
- Improved Machine Performance: The high rigidity minimizes shaft deflection, leading to increased accuracy and operational efficiency.
- Increased Reliability: Robust construction reduces the risk of premature failure, leading to less downtime and more consistent production.
- Simplified Assembly: As a single unit, it is easier to handle and mount compared to a paired set of single-row bearings.
- Cost-Effective Solution: Offers a high-performance alternative to using two separate bearings, reducing component count and installation complexity.
