The 22310 EK/C3 spherical roller bearing is a heavy-duty, self-aligning component engineered for applications requiring high radial load capacity and tolerance to shaft misalignment. Featuring a symmetrical barrel-shaped roller design and an EK-style machined brass cage, this bearing excels in harsh environments such as mining equipment, industrial mixers, and paper mill machinery. Its C3 internal clearance accommodates thermal expansion in high-speed operations (up to 2,800 RPM) while maintaining stability under combined loads and vibrations. Constructed from vacuum-degassed chromium steel with carbonitrided surfaces, the 22310 EK/C3 reshafts abrasive wear and extends service life in contaminated conditions. The bearing's optimized contact angle and raceway geometry reduce friction, enabling reliable performance at temperatures ranging from -30°C to +200°C. Pre-greased with lithium complex lubricant and compliant with ISO 15:2017 standards, it ensures backward compatibility with legacy systems while minimizing maintenance downtime in cement plants, crushers, and wind turbine gearboxes.
