Timken 22215EJW33C3 Spherical Roller Bearing

The Timken 22215EJW33C3 is a double-row spherical roller bearing with a cylindrical bore that self-aligns to accommodate shaft misalignment while carrying heavy radial loads and moderate axial loads in rugged, high-shock equipment. It combines a W33 lubrication groove with three lubrication holes, an EJ hardened steel cage, and a C3 internal clearance, with dimensions of bore 75 mm, outside diameter 130 mm, and width 31 mm. Dynamic load rating is 222 kN and static load rating 240 kN, with reference speeds of 3800 rpm when grease-lubricated and 4600 rpm when oil-lubricated; these specifications support reliable operation under demanding conditions. The bearing’s self-aligning design and hardened cage help reduce operating friction and improve durability in harsh industrial environments such as mining equipment, crushers, vibrating screens, conveyors, paper machines and paper mills, cement plants and cement processing equipment, steel mills, material handling systems, and heavy industrial gearboxes where shaft misalignment and contamination are common. The EJ cage and W33 lubrication groove facilitate robust lubrication delivery and long service life in severe service conditions.
