Torrington22226KW33Double Row Spherical Roller Bearing 130x230x64 mm 1:12 Tapered Bore W33 Lube Groove Brass Cage

Product Description

What this part is

A Torrington 22226-K-W33 double-row spherical roller bearing. Bore 130 mm on a 1:12 taper, outside diameter 230 mm, width 64 mm. Machined brass cage, with a lubrication groove and three radial holes in the outer ring.

Decoding the designation

222 — ISO 222 dimension series, double row spherical roller
26 — bore code, 130 mm bore
K — 1:12 tapered bore
W33 — lubrication groove plus three radial holes in the outer ring
BR / MB — machined brass cage

What these specs mean in practice

The two roller rows run on a common spherical outer raceway, so the bearing accommodates shaft misalignment and carries heavy radial load along with thrust in both directions. A machined brass cage raises the load and speed capability over a pressed steel cage and tolerates higher temperatures. The W33 groove and holes let grease reach the rollers directly through the housing.

Fitting notes

The 1:12 tapered bore seats on an adapter sleeve, which mounts on a plain cylindrical shaft; the sleeve for this bore is an H3126, with a 120 mm shaft seat. Driving the bearing further up the taper reduces internal clearance, so the final position sets the running clearance. The housing bore is aligned with the W33 grease entry.

Interchange guidance

Straight-bore 22226 variants and untapered 22226 W33 bearings share the outside envelope but mount differently and are related sizes rather than interchanges. Cage variants such as a pressed steel 22226-CC-K-W33 carry different ratings and are also a related size.
