This is an SKF 22213 CK/W33 double-row spherical roller bearing with a 65 mm tapered bore, 120 mm outside diameter and 31 mm width. Two rows of barrel-shaped rollers run on a common spherical raceway in the outer ring, allowing the shaft to swivel relative to the housing and absorb misalignment under load.
The 222 prefix is the double-row spherical roller family and the 13 bore code gives 65 mm. The C and J elements specify a pressed steel window cage. K specifies a 1:12 tapered bore rather than a straight one. W33 means the outer ring carries a circumferential lubrication groove and three radial lubrication holes. There is no clearance suffix, so radial internal clearance is normal, CN.
Adapter sleeve H313 fits this bearing and is a separate part, not included. The sleeve seats on a 60 mm plain shaft — one bore-code step below the bearing bore — and is supplied with a KM13 locknut and an MB13 lockwasher. A withdrawal sleeve arrangement or a stepped shaft with a tapered seat are the alternatives to the adapter sleeve.
A double-row spherical roller carries very high radial load and takes axial load in both directions. The 1:12 taper is what makes clearance adjustable at assembly: driving the inner ring further up the taper expands it and reduces running clearance, so the fitter sets the final clearance rather than accepting a fixed value. CN clearance is the general-purpose setting for a shaft and housing running at similar temperatures.
Bearing only, 1 Pc. Supplied without adapter sleeve H313 and without locknut or lockwasher.
The bearing goes up the sleeve taper until the specified radial internal clearance reduction is reached, measured with a feeler gauge across the unloaded roller row or by drive-up distance. The housing lubrication port is aligned with the outer ring W33 groove so the relubrication passage stays open.
Same-spec equivalents are FAG 22213-E1-XL-K, NSK 22213EAKE4 and Timken 22213KEJW33, all 65 mm tapered bore, 120 x 31 mm, with lubrication groove and holes. The straight-bore 22213 CC/W33 and the C3-clearance 22213 CCK/C3W33 share the envelope but differ in bore form and clearance, making them related sizes rather than substitutions.
