30221

The 30221 single row tapered roller bearing is the definitive choice for engineers seeking a robust solution to manage substantial combined forces. Its geometrical configuration, where the apex lines of the raceways and rollers converge at a single point on the bearing axis, is optimized to effectively transmit both high radial forces and significant unidirectional axial loads. This makes the 30221 indispensable in heavy-duty machinery, agricultural equipment, and vehicle axles where stability and load distribution are critical. Manufactured with precision-ground components, this bearing ensures smooth running characteristics and superior mechanical efficiency, making it a foundation for durable and dependable rotating assemblies.

Dimensionally, the 30221 unit maintains an industry-standard outer diameter of 190 mm and a bore of 105 mm, designed to fit standard machine housings and shafts. A key operational benefit is the two-piece, separable design: the cone (inner ring assembly) and the cup (outer ring) can be mounted independently. This feature dramatically simplifies the installation process and subsequent maintenance routines. Furthermore, the inherent design allows maintenance staff to finely adjust the bearing's internal clearance or apply a preload during assembly, which is crucial for achieving peak system rigidity, minimizing shaft run-out, and ultimately extending the functional lifespan of the equipment.
