Timken 22218EJW33C3 Double Row Spherical Roller Bearing

Timken 22218EJW33C3 is a double-row spherical roller bearing with a cylindrical bore engineered for heavy-duty rotating equipment that must support high radial loads, moderate axial loads, and shaft misalignment. It features a 90 mm bore, 160 mm outside diameter, and 40 mm width, with a C3 internal clearance and an EJ hardened steel cage for durability; the W33 lubrication groove includes three lubrication holes to maintain proper lubrication under demanding service. The bearing's dynamic load rating is 355 kN and static load rating is 388 kN, with reference speeds of 3400 rpm (grease) and 4100 rpm (oil). Its self-aligning design and enhanced lubrication contribute to reduced operating friction and high shock-load capacity, making it suitable for crushers, vibrating screens, conveyors, paper machines, mining equipment, material handling systems, cement processing equipment, and heavy industrial gearboxes in harsh environments. The Timken part number 22218EJW33C3 is commonly used in mining, cement, steel, and processing facilities where misalignment and contamination are present and reliable performance is essential.
