22309K Spherical roller bearing

The 22309K is a spherical roller bearing from the 223 series with a 45 mm tapered bore (1:12 taper). Spherical roller bearings feature two rows of barrel-shaped rollers running on a common spherical outer ring raceway, providing self-aligning capability to compensate for shaft deflection and misalignment.

This bearing type is commonly used in heavy industrial applications including mining equipment, construction machinery, paper mills, and gearboxes where misalignment compensation and high radial load capacity are required. The tapered bore design allows mounting directly on tapered shafts or adapter sleeves for easier installation and removal.
