How the 24144-CCK30-W33 model number is decoded

In SKF catalogue PUB BU/P1 17000, 24144-cck30-w33 denotes the tapered-bore version (K30 suffix, taper 1:30) of the 24100-series spherical roller bearing: dimensioned 220×370×150 mm, it seats on an adapter or withdrawal sleeve rather than directly on a machined journal. Digit by digit, 24144-cck30-w33 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 41, and bore reference 44 resolving to 220 mm; 370 mm OD and 150 mm width are the matching ISO 15 boundary values. Sleeve mounting is why the K30 execution exists: a plain h9-tolerance shaft is enough because the adapter sleeve supplies the precision seat, and the bearing is removable without pulling over an interference journal — a separate order number from the cylindrical-bore bearing, never a field conversion. Catalogue mass 76000 g for the 220×370×150 mm open execution covers the two pressed-steel cages with a floating guide ring; tapered-bore and sealed variants differ in mass and carry their own order numbers. After drive-up, re-check radial clearance and then swing the outer ring through its self-aligning range: the sphered raceway of the 24144-cck30-w33 must still tilt ≈ 0.5–2.5° freely — a joint that binds after sleeve mounting signals excessive drive-up or a cocked sleeve.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 220 mm bore the ring mass makes cocking during mounting a real risk; guide the bearing square, confirm seat contact around the full circumference, and re-check the self-aligning swing after the housing cap is torqued down.
• The 24100-series series at 220 mm bore (370×150 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 1,200 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
• The adapter sleeve is selected by actual shaft diameter, not by the 220 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24144-cck30-w33 with different sleeves.
• The 24144-cck30-w33 and its cylindrical-bore counterpart 24144-cc-w33 share envelope and load ratings (2197/3350 kN) but are not interchangeable in a housing already fitted for direct shaft mounting — the sleeve changes the assembly stack-up.
• The 24144-cck30-w33 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 2197/3350 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
• The 2197/3350 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24144 CCK30/W33); sleeve, KM nut and MB washer are separate order numbers, and the catalogue version (SKF catalogue PUB BU/P1 17000) should travel with the mounting specification.
