How the 24024-CCK30-W33 model number is decoded
For sleeve mounting on a 120 mm shaft, SKF order number SKF 24024 CCK30/W33 is the 1:30 tapered-bore spherical roller bearing in the 24000-series family (dimension series 40 (compact OD, maximum width)); the cylindrical-bore equivalent is a separate order number, 24024-cc-w33. Reading the designation: the leading 2 marks a spherical roller bearing, the 40 is the ISO 15 dimension series (dimension series 40 (compact OD, maximum width)), and the last two digits encode the 120 mm bore; the 180 mm OD and 60 mm width follow the ISO 15 general plan. The K30 in the designation marks the 1:30 tapered bore: SKF mounts it on an H-series adapter sleeve (with KM locknut and MB lock washer) on a plain commercial-grade shaft, or on an AH withdrawal sleeve where the bearing must abut a shaft shoulder. The 30.0 mm radial section height ((180−120)/2) and 5950 g catalogue mass frame a 120 mm bore bearing rated at 456 kN C — roughly 3.80 kN of dynamic capacity per millimetre of bore before application factors. For shafts with a locating shoulder, use an AH withdrawal sleeve instead of an adapter sleeve: the bearing presses against the shoulder and the sleeve is drawn out for dismounting, making the 24024-cck30-w33 removable without an induction heater.
Typical equipment & failure modes
Common applications
- wind-turbine main shaft support
- heavy rolling-mill work-roll chocks
- split-housing plummer block arrangements with bearings swapped in situ
- heavy crusher and screen shafts mounted and dismounted with hydraulic nuts
Known failure patterns
- raceway fatigue spalling of the sphered outer raceway after extended service above the catalogue L10 rating
- inner-ring raceway spalling from edge loading when misalignment exceeds the self-aligning recovery range
- sleeve seizure and shaft seat damage from omitting the anti-seize film between withdrawal sleeve and journal before drive-up
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- At 120 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 120 mm bore (180×60 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 120 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24024-cck30-w33 with different sleeves.

- The 5950 g mass and 60 mm width mean abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the outer ring and concentrates load on one roller row of 24024-cck30-w33.
- The 456/670 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24024 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.
Frequently asked questions
What are the dimensions and catalogue data of 24024-cck30-w33?
The SKF 24024 CCK30/W33 is a double-row spherical roller bearing with a 1:30 tapered bore, 120 mm nominal bore, 180 mm outer diameter and 60 mm width (4.724 × 7.087 × 2.362 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 456 kN, C0 670 kN, Pu 68 kN, reference speed 2,400 r/min, limiting speed 3,400 r/min, mass about 5950 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K30 suffix mean on 24024-cck30-w33?
K30 (written CCK30/W33 in the CC execution) marks the 1:30 tapered bore for sleeve mounting. The bearing seats on an H-series adapter sleeve with a KM locknut and MB lock washer (plain shaft, h9 tolerance), or on an AH withdrawal sleeve against a shaft shoulder.
Which adapter sleeve fits the 24024-cck30-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 120 mm nominal bore: SKF H-sleeve numbers each cover a small shaft-diameter range and are width-series specific (H39/H30/H31/H32 matching dimension series 39/40/31/32), and each kit bundles the sleeve, KM locknut and MB lock washer. For shoulder locations use an AH withdrawal sleeve instead. Confirm the sleeve number against the SKF catalogue PUB BU/P1 17000 mounting tables for your shaft size.
How is the 24024-cck30-w33 driven up and checked?
Mounting is controlled by radial-clearance reduction or axial drive-up distance from the SKF catalogue tables for the 1:30 taper, never by locknut torque. Measure clearance with feeler gauges before and after tightening the KM nut, stop at the tabulated decrease, and lock the MB washer tab. Over-drive removes too much clearance (inner-ring cracking risk); under-drive lets the sleeve creep and fret.
What is the difference between 24024-cck30-w33 and 24024-cc-w33?
They share the ISO 15 envelope and the same 456/670 kN ratings, but 24024-cck30-w33 has the 1:30 tapered bore for sleeve mounting on a plain shaft, while 24024-cc-w33 has a cylindrical bore for direct mounting on a machined interference journal (typically m6 with H7 housing). They are separate order numbers, not interchangeable in the same shaft arrangement.
