22218 EK-C3 bearing

Application:

Designed for durability and low maintenance, the 22218 EK/C3 bearing incorporates a stamped steel cage and features for easy relubrication. Its ability to carry heavy radial and axial loads in both directions makes it a preferred choice for machinery in sectors such as mining, agriculture, heavy construction, and material handling. By effectively managing misalignment and providing high static and dynamic load ratings (up to 375 kN static), this roller bearing is critical for reducing downtime and extending the service life of industrial equipment. When specifying the 22218 EK/C3, pairing it with the correct adapter and withdrawal sleeves (like the H318 series) is recommended for optimal installation and performance.

Features:

The 22218 EK/C3 Spherical Roller Bearing is engineered for demanding industrial applications, offering exceptional performance and reliability. Featuring a 90 mm inner diameter, 160 mm outer diameter, and 40 mm width, this double-row bearing boasts an optimized internal design for significantly increased load capacity. The "EK" designation highlights its crucial specifications: an E-type internal design (enhanced capacity) and a K (1:12) tapered bore, which facilitates mounting via an adapter sleeve onto a plain shaft. Importantly, the C3 radial internal clearance is greater than the standard, making it ideal for applications involving high-speed, thermal expansion, or fitting with interference. This self-aligning design allows the bearing to accommodate substantial misalignment and shaft deflections, ensuring reliable operation without a major increase in friction or temperature.
