Tapered Roller Bearing – 30309 J2/Q

The SKF 30309 J2/Q is a high-performance single row tapered roller bearing designed for applications requiring dependable handling of both radial and axial loads. Its conical raceways and tapered rollers ensure even load distribution, reducing friction and enabling smooth, efficient operation across a wide range of machinery.

The separable design of this bearing, consisting of a cone unit (inner ring, cage, and roller set) and an outer cup, allows for simplified mounting, dismounting, and maintenance. This feature also enables interchangeable use of components. As with all single row tapered roller bearings, the 30309 J2/Q has an open design and should be mounted with a second bearing in mirror-image arrangement for balanced axial load management. Depending on application requirements, paired sets can be configured in X, O, or tandem arrangements to optimize rigidity and support.

Manufactured from high-quality bearing steel with a sheet metal cage, the SKF 30309 J2/Q provides durability, reliability, and long service life. Its robust design makes it well-suited for heavy-duty industrial applications such as gearboxes, transmissions, and rotating equipment, where consistent performance is critical.
