22320 EK

The 22320 EK spherical roller bearing stands as a cornerstone for heavy-duty industrial rotating systems, engineered to thrive where shaft misalignment or deflection is a constant challenge. Featuring a 100mm bore, 215mm outside diameter, and a robust 73mm width, this double-row bearing is designed to handle massive radial loads and significant axial forces in both directions. The "EK" designation signifies a 1:12 tapered bore, which, when paired with an adapter sleeve, allows for precise mounting and easy adjustment of radial internal clearance on straight shafts. Unlike standard bearings that struggle with geometric errors, the self-aligning nature of the 22320 EK ensures continuous operation with minimal friction, even under the stress of heavy vibration or mounting inaccuracies.

Beyond its physical dimensions, the 22320 EK is a reliability upgrade for demanding environments like mining, construction, and paper mill machinery. Its internal architecture, often featuring a stamped steel cage and an optimized roller-to-raceway contact, significantly reduces heat generation, which is a leading cause of premature bearing failure. With a dynamic load rating of approximately 847 kN and a limiting speed of 3,000 r/min, this bearing excels in high-torque applications where uptime is critical. The inclusion of an annular groove and lubrication holes in the outer ring simplifies maintenance, ensuring that the rolling elements remain well-lubricated to extend service life and reduce the total cost of ownership for your equipment.
