How the 24048-CCK30-W33 model number is decoded

The SKF 24048 CCK30/W33 is a 240×360×118 mm spherical roller bearing with a 1:30 tapered bore — SKF catalogue execution for sleeve mounting on a 240 mm plain shaft, retaining the double-row self-aligning barrel-roller design. On the SKF nameplate, 24048-cck30-w33 follows the ISO 15 convention: 2 for the spherical roller type, 40 for the dimension series 40 (compact OD, maximum width), final digits 48 for the 240 mm bore. 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 50500 g for the 240×360×118 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 24048-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 240 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 24000-series series at 240 mm bore (360×118 mm) packs maximum roller length into the smallest OD envelope — very high C0 for its size but the lowest speed ceiling; never swap it for a wider-OD 231 bearing without re-checking the housing bore and the speed margin.
• The adapter sleeve is selected by actual shaft diameter, not by the 240 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24048-cck30-w33 with different sleeves.
• Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24048-cck30-w33 to a bearing of the other taper (1:12 vs 1:30); the steeper taper moves far less clearance per nut turn and the targets come from different catalogue tables.
• Open spherical roller bearings rely on the housing seals; in screening or crusher duty a failed seal lets grit into the sphered raceway and the 24048-cck30-w33 pits long before its L10 life.
• The 1663/2700 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24048 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.
