An RHP 22218W33C3 double-row spherical roller bearing. Bore Diameter: 90 mm. Bore Type: Straight cylindrical. Outside Diameter: 160 mm. Overall Width: 40 mm. Series: 22200, the narrow section of the spherical roller range. Maximum Permissible Misalignment: 2°. Both roller rows run on one spherical outer raceway, so the inner ring and roller assembly swivel inside the outer ring and the bearing accepts shaft deflection and housing misalignment.
22218 — the narrow spherical series with the ISO bore code 18 for 90 mm.
W33 — a lubrication groove around the outer ring with three radial feed holes.
C3 — internal radial clearance greater than normal.
22218C, 22218CC, 22218CJ and 22218CCJ — the carton alternates, cage-code variants of the same section.
The self-aligning geometry carries heavy radial load and accommodates around two degrees of misalignment, which is why spherical rollers are standard on conveyor pulleys, fans, crushers, vibrating screens and gearbox output shafts. The two roller rows sit at opposing angles, so the bearing takes thrust in both directions as well as radial load. C3 clearance leaves running room for thermal growth of the inner ring relative to the outer and suits a warm or interference-fitted application. The W33 groove and holes deliver grease or oil to the rolling elements straight from the housing.
Unit Quantity: 1 Pc. Closure Type: Open on both faces. The straight bore mounts directly on the shaft.
Interference fit on the shaft journal, with the outer ring located in the housing bore. The three W33 feed holes align with the housing lubrication port.
Direct equivalents on the same envelope and clearance are the SKF 22218 E/C3 and the FAG 22218-E1-C3. A 22218K with a 1:12 taper bore is a related size, because it mounts on an H2318 adapter sleeve and its shaft seat is 80 mm. A 22218 in normal CN clearance is a separate part, as is a 22218 with a brass cage in place of a pressed steel one.
