The 22218 and 22220 series spherical roller bearings are engineered for the extreme environments found in steel mills, paper factories, and large-scale industrial pumps. These bearings are built to handle massive radial loads and significant impact forces that occur during the heavy-duty rolling and crushing processes. The internal geometry of the 22218/22220 is optimized for maximum surface contact, providing an exceptionally high dynamic load rating. We utilize vacuum-degassed chrome steel to minimize impurities, ensuring the bearing has the fracture toughness required to resist surface fatigue and flaking. To accommodate the thermal expansion of shafts in high-temperature environments, we offer these models with C3 and C4 internal clearances. The machined brass cage (EM/MA) options provide superior vibration resistance and are ideal for the high-frequency cycles typical of industrial fans and vibrating screens. Every unit is meticulously inspected for radial runout and dimensional accuracy to ensure a perfect fit in large-scale industrial housings. By integrating these robust bearings into your heavy machinery, you significantly increase the interval between maintenance cycles, leading to higher factory throughput and reduced operational costs.
