Decoding the designation

22210 — FAG’s number for the ISO 210 spherical roller size, 50 x 90 x 23 mm.

E1 — reinforced internal execution with a higher roller complement.

K — 1:12 tapered bore, mounts on an H310 adapter sleeve.

C3 — radial internal clearance greater than normal.

W33 — annular lubrication groove in the outer ring outside diameter with three radial feed holes into the roller track.

What these specs mean in practice

Dynamic Load Rating: 109 kN. Static Load Rating: 107 kN. Fatigue Limit Load: 14.3 kN. Limiting Speed: 9,500 r/min. Mass: 0.622 kg. The sphered outer raceway lets the inner ring and both roller rows swivel bodily inside the outer ring, so the bearing absorbs shaft deflection and housing misalignment without edge loading, and the two opposed rows take thrust in either direction as well as the radial load. Internal Clearance: C3, above normal, which is what a tapered-bore mounting wants: driving the inner ring up the sleeve taper expands it and consumes clearance, so the assembly starts above normal and finishes at the right figure. Lubricant: grease or oil. The W33 groove distributes lubricant circumferentially around the outer ring and its three radial holes carry it inward to the rollers, which suits a grease gun, a single-point lubricator or a circulating-oil feed equally.

Mounting data

Bore: 50 mm, 1:12 taper. Outside Diameter: 90 mm. Overall Width: 23 mm. The 50 mm tapered bore seats on an H310 adapter sleeve, whose tapered outside diameter is 50 mm over a 45 mm cylindrical shaft seat, secured with a KM 10 locknut and an MB 10 lockwasher. Radial internal clearance is set by measured drive-up on the taper rather than by shaft tolerance. The W33 groove and holes align with a housing lubrication port.

Quantity and configuration

Unit Quantity: 1 Pc. Supplied as a single bearing.

Interchange guidance

Manufacturer part number variants: 22210EK.C3, 22210-E-K-C3-W33, 22210-E1-K-C3, 22210EKC3W33, 22210EK, 22210 K. The 22210 K envelope is an ISO-standard spherical roller size, so an SKF 22210 EK/C3W33, NSK 22210 EAKE4 C3 and Timken 22210KEJW33C3 share the 50 x 90 x 23 mm boundary dimensions and the 1:12 taper. A straight-bore 22210-E1-C3 is the same bearing on a cylindrical seat, so it is a related size rather than an interchange.
