Koyo 22211RHKW33C3 is a double-row spherical roller bearing with a 1:12 tapered bore, an annular lubrication groove in the outer ring and C3 internal clearance. Unit Quantity: 1 Pc. Single bearing with a tapered bore, open on both faces. Two rows of barrel rollers run on a common spherical raceway in the outer ring, so the inner ring, rollers and cage swivel inside the outer ring and the bearing accommodates shaft deflection and housing misalignment while carrying heavy radial load and thrust in both directions.
222 — ISO dimension series 22, the wider section of the double-row spherical roller range.
11 — bore code 11, giving 55 mm.
RH — symmetric rollers running in a pressed steel cage.
K — 1:12 tapered bore.
W33 — annular lubrication groove around the outer ring with three radial feed holes.
C3 — internal radial clearance greater than normal.
Rolling Elements: Spherical Roller. Number Of Rows: 2. Bore Type: Tapered 1:12. Internal Clearance: C3. Cage Material: Pressed steel. Closure Type: Open. Bearing Material: Chrome steel. Lubricant: Grease or oil. Relubrication: W33 annular groove with three radial feed holes. Series: 222. Base Number: 22211.
Bore Diameter: 55 mm. Outside Diameter: 100 mm. Overall Width: 25 mm. The 1:12 tapered bore mounts on an adapter sleeve. The matching sleeve for a 55 mm bore is an H311, whose tapered outside diameter is 55 mm and whose shaft seat is 50 mm. Locknut: KM11. Lockwasher: MB11.
The same bearing is written 22211RHKW33C3, 22211-RH-K-W33-C3 and 22211RHKW33. Related numbers on the 55 x 100 x 25 mm size with a 1:12 tapered bore: SKF 22211 EK/C3 (no outer-ring groove), FAG 22211-E1-K-C3, NSK 22211EAKE4C3, NTN 22211EAK (no groove, normal clearance), Timken 22211KEJW33C3, Torrington 22211KCJW33C3, Nachi 22211EXKW33C3, NTN-SNR 22211EAKW33C3, Koyo 22211RHRKW33C3 (RHR roller and cage execution). The straight-bore form of the same size is written 22211RHW33C3 and mounts directly on a cylindrical shaft seat, so it is a related size rather than an interchange.
What are the bore, outside diameter and width?Bore Diameter: 55 mm. Outside Diameter: 100 mm. Overall Width: 25 mm.
Which adapter sleeve fits it?The 1:12 tapered bore mounts on an H311 adapter sleeve, with KM11 locknut and MB11 lockwasher.
What do W33 and C3 mean?W33 is an annular lubrication groove around the outer ring with three radial feed holes. C3 is internal radial clearance greater than normal.
