22312 EK

The 22312 EK Spherical Roller Bearing is engineered for demanding industrial applications, offering exceptional reliability and performance under heavy load conditions. This double-row bearing features an optimized internal design, resulting in a high load-carrying capacity for both radial and axial forces. A key characteristic is its self-aligning capability, allowing it to accommodate significant shaft misalignment and deflection without an increase in friction or operating temperature. The "EK" designation specifically highlights its tapered bore (1:12 taper) and robust stamped steel cage, which together facilitate easy mounting-often with an adapter or withdrawal sleeve-and ensure reliable operation even in challenging environments like crushers, vibrating screens, and heavy-duty gearboxes. With an internal diameter of 60 mm, an outside diameter of 130 mm, and a width of 46 mm, the 22312 EK is a foundational component for reliable rotating machinery.

Designed for longevity and reduced maintenance downtime, the 22312 EK bearing includes essential features such as relubrication holes and a groove in the outer ring. This feature allows for the convenient reapplication of lubricant, significantly extending the bearing's service life and operational efficiency in continuous running applications. Its robust construction minimizes friction and heat generation, maintaining stability at high operating speeds, which are rated up to 5,300 r/min (limiting speed). When selecting this bearing, consider its impressive dynamic load rating (C), which is typically around 325 kN, confirming its suitability for the heaviest tasks. Choosing the 22312 EK means investing in a high-performance component that delivers superior resistance to wear and ensures maximum uptime for your critical machinery.
