Decoding the designation

22217 is the ISO 222 dimension series at an 85 mm bore. E marks the high-capacity internal design, with larger rollers than the base series on the same envelope. K gives Bore Type: Tapered 1:12, mounting on an adapter sleeve rather than on a plain shaft. J is the pressed steel cage. W33 is the lubrication groove and its three radial holes. C3 sets Internal Clearance: C3, greater than the normal group.

What these specs mean in practice

Dynamic Load Rating: 296 kN. Static Load Rating: 325 kN. Limiting Speed: 4,300 rpm. Maximum Operating Temperature: 200 °C. Minimum Operating Temperature: -40 °C. Lubricant: grease or oil. Two rows of barrel rollers run on a common spherical outer raceway, so the inner ring and roller set swivel inside the outer ring and absorb shaft-to-housing misalignment under full load. Thrust is carried in both directions. C3 clearance leaves more room for thermal growth and interference fits than the normal group, which suits a hot running shaft or a heavy press fit. The W33 groove distributes lubricant circumferentially around the outer ring and the three radial holes carry it inward to the rolling elements, taking either grease or a circulating oil feed. Rings are dimensionally stabilised for service to 200 °C.

Fitting notes

Adapter Sleeve: H317. The sleeve’s tapered outside diameter is 85 mm to match this bore and its own bore seats a 75 mm shaft. An H317 takes a KM17 locknut and an MB17 lockwasher. Drive-up on the taper sets the mounted radial internal clearance, so the C3 figure is the as-delivered clearance before mounting. The housing lubrication port lines up with the W33 groove in the outer ring.

Interchange guidance

Direct equivalents on the 85 x 150 x 36 mm tapered-bore envelope with a W33 groove and C3 clearance: SKF 22217 EK/C3, FAG 22217E1.K.C3, Timken 22217EJW33KC3, NSK 22217EAKE4C3. A 22217E without the K is a related size on a straight bore, mounting directly on the shaft with no sleeve. A 22217EKJW33 in the normal clearance group is a related size at CN.
