How the 23024-CCK-W33 model number is decoded

Ordering number SKF 23024 CCK/W33 in SKF catalogue PUB BU/P1 17000 is a double-row spherical roller bearing with a tapered bore (1:12), intended for an H-series adapter sleeve or AH withdrawal sleeve, with two pressed-steel cages with a floating guide ring and the same 120×180×46 mm ISO 15 outline as its cylindrical-bore counterpart. On the SKF nameplate, 23024-cck-w33 follows the ISO 15 convention: 2 for the spherical roller type, 30 for the dimension series 30 (slim OD, extra-wide), final digits 24 for the 120 mm bore. Sleeve mounting is why the K 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. The 30.0 mm radial section height ((180−120)/2) and 5950 g catalogue mass frame a 120 mm bore bearing rated at 366 kN C — roughly 3.05 kN of dynamic capacity per millimetre of bore before application factors. Over-driving the 23024-cck-w33 up its sleeve pinches radial clearance below the residual minimum and can crack the inner ring in service; under-driving leaves the sleeve seat loose, so the ring creeps and frets the sleeve — measure, do not estimate.

Typical equipment & failure modes

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 23000-series series at 120 mm bore (180×46 mm) is the slim-OD envelope: it buys radial space but gives up capacity against a 222-series bearing of the same bore — confirm the L10 margin before downsizing into it.
• 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 23024-cck-w33 with different sleeves.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 46 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• The 23024-cck-w33 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 366/500 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
• The 366/500 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 23024 CCK/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.
