Product Overview: The 30306 Tapered Roller Bearing
The 30306 bearing is a single-row tapered roller bearing engineered to handle high combined radial and axial loads. With dimensions of 30x72x20.75mm, this component is a staple in our 30300 Series and the broader Tapered Roller Bearings collection. Its unique design, featuring tapered inner and outer ring raceways and tapered rollers, allows for true rolling motion and low friction. This makes it exceptionally well-suited for applications where heavy and complex loads are present, such as in automotive wheel hubs, gearboxes, and various industrial machinery.
A key feature of the 30306 bearing is its separable design. The inner ring with the roller and cage assembly (the cone) can be mounted separately from the outer ring (the cup). This simplifies installation, inspection, and maintenance procedures. Manufactured from high-quality bearing steel, this bearing provides excellent durability and reliable performance in demanding operational environments.
Key Features of the 30306 Bearing
- High Load Capacity: Designed to accommodate heavy radial and axial loads in one direction, making it ideal for robust applications.
