23120K Spherical roller bearing

The 23120K is a spherical roller bearing with a 100mm tapered bore (1:12 taper) from the 231 series. Spherical roller bearings feature two rows of symmetrical rollers running on a common spherical outer ring raceway, providing self-aligning capability to accommodate shaft deflection and misalignment.

This bearing type is designed for heavy radial loads and moderate thrust loads in applications such as industrial gearboxes, mining equipment, paper mills, and heavy machinery where shaft misalignment or deflection is present. The tapered bore allows secure mounting directly on tapered shafts or adapter sleeves.
