Timken 22218EJW33C3 Double Row Spherical Roller Bearing

The Timken 22218EJW33C3 is a double-row spherical roller bearing with a cylindrical bore designed to support heavy radial loads, moderate axial loads, and shaft misalignment in harsh industrial environments. It features a 90 mm inside diameter bore, 160 mm outside diameter, and 40 mm width, with C3 internal clearance and an EJ hardened steel cage. The bearing uses a W33 lubrication groove with three lubrication holes to improve lubricant delivery and reliability, and it carries a dynamic load rating of 355 kN and a static load rating of 388 kN. Reference speeds are 3400 rpm with grease or 4100 rpm with oil, depending on lubrication, reflecting its suitability for high-load, rotating equipment. Commonly installed in mining equipment, crushers, conveyors, paper mills, cement plants, steel mills, gearboxes, and other heavy industrial processing machinery where shaft misalignment, shock, vibration, and contamination are present.
