22220 EK

22220 EK Spherical Roller Bearings are heavy-duty components engineered for applications requiring high radial and axial load capacity with misalignment compensation. Designed with a symmetrical barrel-shaped roller configuration and an inner ring guided brass cage (denoted by "EK"), this model ensures smooth operation in harsh environments like mining, cement processing, and industrial gearboxes. The 22220 designation specifies a 100mm bore, 180mm OD, and 46mm width, supporting dynamic/static load ratings up to 305kN/325kN. Its self-aligning feature tolerates up to 2.5° shaft deflection, reducing stress from mounting errors or housing deformation. Heat-treated chromium steel construction and advanced surface finishing enhance wear resistance, while optimized lubrication grooves extend service intervals. The bearing operates reliably at temperatures ranging from -30°C to 150°C and is pre-lubricated with lithium-based grease for immediate installation. Compliant with ISO 15:2017 standards, it suits vibratory screens, conveyor systems, and pulp/paper machinery, offering 20% longer fatigue life than conventional designs. OEMs value its ABEC-1 precision balance and corrosion-resistant options for marine or chemical exposure.
