FAG22224RSpherical Roller Bearing – Straight Bore, 120 mm ID, 215 mm OD, 58 mm Width, Open, Double Row, CN Internal Clearance

Product Description

What this part is

FAG 22224R double-row spherical roller bearing, 120 mm bore, 215 mm outside diameter, 58 mm width. The two rows of barrel-shaped rollers run on a common spherical raceway ground into the outer ring, so the inner ring, rollers and cage assembly can swivel within the outer ring and accommodate shaft misalignment and shaft deflection without edge-loading the raceways.

Decoding the designation

In the 222xx series the last two digits are the bore code — 24 × 5 mm gives the 120 mm bore. The 222 prefix denotes the lighter of the two common spherical roller width series. There is no K in the designation, so the bore is straight and cylindrical and the bearing mounts directly on a ground shaft seat. The carton also carries the designations 22224-R and 22224-HL-MB.

What these specs mean in practice

A double-row spherical roller bearing carries very high radial load and takes thrust in both directions, and it is the standard choice where a long shaft, a fabricated frame or separately machined housings make perfect alignment impractical. The trade-off against a cylindrical roller bearing of the same envelope is speed: the spherical raceway and barrel rollers generate more sliding contact, so the limiting speed sits lower. Published capacity for this size is 610 kN dynamic and 765 kN static.

Bore form

Straight bore. The shaft seat diameter equals the 120 mm bore, and axial location is by shaft shoulder, spacer or locknut against the inner ring face. The tapered-bore variant of this size, 22224-K, is a related part that mounts on an H3124 adapter sleeve.

Quantity and configuration

One bearing, complete with inner ring, outer ring, both roller rows and the cage. Open on both faces.

Interchange guidance

The 22224 boundary dimensions are ISO-standard, so SKF 22224 E, Timken 22224EM and NSK 22224EAE4 share the same 120 × 215 × 58 mm envelope. Cage material, clearance class and the presence or absence of a W33 lubrication groove vary between those executions and change the rating and the relubrication provision, so match the full suffix rather than the base number where those features matter.
