FAG22224HLASKW33Spherical Roller Bearing – 1:12 Tapered Bore, 120 mm ID, 215 mm OD, 58 mm Width, Open, Double Row, Solid Brass Cage, W33 Lubrication Groove

Product Description

What this part is

FAG 22224HLASKW33 double-row spherical roller bearing, 120 mm tapered bore, 215 mm outside diameter, 58 mm width. Two rows of barrel rollers run against a single spherical raceway ground into the outer ring, so the inner ring and roller assembly can swivel inside the outer ring and absorb shaft misalignment and shaft deflection without edge-loading the raceways.

Decoding the designation

The full carton designation is 22224-HL-AS-K-MB-W33. In the 222xx series the last two digits are the bore code, so 24 × 5 mm gives the 120 mm bore. HL denotes the increased-capacity internal design. AS is the lubrication groove with radial feed holes machined into the outer ring. K is a 1:12 tapered bore. MB is a machined solid brass cage. W33 is the annular groove around the outer ring with three radial lubrication holes into the roller path.

Bore form

The bore is tapered on a 1:12 ratio, measuring 120 mm at the large end. A tapered bore mounts on an adapter sleeve, and the matching sleeve for this size is an H3124, which seats on a 110 mm shaft and is secured with a KM24 locknut and an MB24 lockwasher. The AH3124 withdrawal sleeve is the alternative where the shaft has a shoulder. Driving the bearing further up the sleeve taper reduces radial internal clearance, so the drive-up distance sets the mounted clearance directly.

What these specs mean in practice

Basic dynamic capacity is 560 kN and basic static capacity 735 kN. A double-row spherical roller bearing carries very high radial load and takes thrust in both directions. The solid brass cage tolerates higher temperature, shock loading and marginal lubrication better than a pressed steel cage, which is why it is specified on heavily loaded conveyor pulleys, crushers, fans and mill drives. The tapered bore and sleeve allow mounting anywhere along a plain shaft with no machined bearing seat, which is what makes this execution the standard fit for long conveyor and pulley shafts.

Lubrication provision

The W33 groove and its three holes let grease or oil be fed through the housing directly into the loaded zone between the two roller rows, so the bearing can be relubricated without dismounting. The housing bore needs a matching feed port for that path to be used.

Quantity and configuration

One bearing, complete with inner ring, outer ring, both roller rows and the brass cage. Open on both faces, no snap ring groove. The H3124 adapter sleeve, KM24 locknut and MB24 lockwasher are separate parts.

Interchange guidance

The 120 × 215 × 58 mm tapered-bore envelope is ISO-standard, so SKF 22224 CCK/W33, NSK 22224EAKE4 and Timken 22224KEMW33 occupy the same space and take the same H3124 sleeve. The straight-bore 22224 of the same size is a related part rather than an interchange, because it seats directly on a ground shaft and takes no sleeve.
