Product Description

What this part is

SKF 22234 CCK/C2W33 double-row spherical roller bearing. Bore: 170 mm, 1:12 tapered. Outside diameter: 310 mm. Width: 86 mm. Series: 222. Open on both faces, with a W33 lubrication groove and three feed holes in the outer ring. Weight: 61.7 lb.

Decoding the designation

222: dimension series, double row. CC: pressed steel window cage with an inner-ring guide ring. K: 1:12 tapered bore. C2: internal clearance tighter than normal. W33: lubrication groove and three radial holes in the outer ring.

What these specs mean in practice

Dynamic load rating: 1,183 kN (265,900 lbf). Static load rating: 1,460 kN (328,200 lbf). Limiting speed: 2,600 rpm. The two roller rows run on a common sphered outer raceway, so the bearing carries heavy radial load, takes thrust in both directions, and accommodates shaft-to-housing misalignment. C2 clearance holds the shaft more closely located than the normal class once the tapered bore is driven up onto its seat.

Bore form and adapter sleeve

The 1:12 tapered bore mounts on an adapter sleeve. The matching sleeve for a 22234 K is an SKF H3134, which seats on a 150 mm shaft and locks with a KM 34 nut and an MB 34 lock washer. Driving the bearing further up the taper reduces the residual clearance, which is how the mounted clearance is set.

Quantity and configuration

One bearing per unit.
