30309

The 30309 single row tapered roller bearing is engineered to manage high-capacity radial and axial loads simultaneously, making it a critical component for heavy-duty industrial rotating systems. Featuring a standard metric dimension of 45mm (bore) x 100mm (OD) x 27.25mm (width), this bearing is designed with a separable "cup and cone" structure. This unique design allows the inner ring assembly (cone) and the outer ring (cup) to be mounted independently, significantly simplifying installation and maintenance in complex machinery. Crafted from high-grade chrome steel, the 30309 model offers exceptional fatigue resistance and dimensional stability under extreme operating temperatures, ensuring a long service life even in harsh environments.

Beyond its robust construction, the 30309 bearing excels in precision and efficiency. Its optimized internal geometry reduces friction and heat generation, which is vital for high-speed applications such as automotive transmissions, gearboxes, and agricultural equipment. By distributing stress evenly across the tapered rollers, it effectively handles unidirectional axial thrust, providing the rigidity required for stable shaft alignment. Whether you are replacing a worn-out part in a mining conveyor or integrating it into a new mechanical drive, the 30309 bearing delivers the reliability needed to minimize downtime and enhance overall system performance.
