Description
The SKF 30307 J2/Q is a robust single row tapered roller bearing engineered for applications where both radial and axial load capacity are critical. Its conical raceway design distributes loads efficiently, enabling reliable operation under high-stress conditions while maintaining low friction.
This bearing consists of a separable cup and cone assembly: the cone unit contains the inner ring, cage, and tapered rollers, while the outer cup forms the outer ring. This separable design allows straightforward mounting, dismounting, and maintenance.
The 30307 J2/Q features a sheet metal cage for stability and strength under dynamic operating conditions. With an open construction, it must be mounted in mirror-image pairs or in X, O, or tandem arrangements for optimal performance in axial load management. Its high load ratings, excellent speed capability, and SKF quality construction make it suitable for gearboxes, transmissions, and general industrial machinery.
