How the 24132-CCK30-W33 model number is decoded

24132-cck30-w33 is the 1:30 tapered-bore execution of the 24100-series spherical roller bearing: the same two barrel-roller rows on a sphered outer raceway as 24132-cc-w33, but the inner-ring bore tapers 1 mm per 30 mm for adapter- or withdrawal-sleeve mounting, as listed by SKF in SKF catalogue PUB BU/P1 17000. Numbering ties the bearing to its envelope: 24132-cck30-w33 means spherical-roller type, dimension series 41, 160 mm bore — which is why the 270×109 mm outline swaps dimensionally with other ISO 15 bearings of the same code. Note that K30 means the 1:30 taper used on dimension series 40/41; the more common K means 1:12. Adapter sleeves (H) and withdrawal sleeves (AH) are ordered separately by shaft diameter, and the KM locknut plus MB lock washer used for drive-up are also separate components. Selection arithmetic: the C0/C ratio is about 1.43 (static 1760 kN against dynamic 1227 kN), typical of a spherical roller sized for heavy combined loads, and the 163 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. 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 24132-cck30-w33 removable without an induction heater.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 160 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 160 mm bore (270×109 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 1,900 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 160 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24132-cck30-w33 with different sleeves.
• Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24132-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.
• The self-aligning feature is not a license to ignore alignment: beyond ≈ 0.5–2.5° (series-dependent) the edge loading eats the fatigue margin, and seal drag grows as the rings tilt.
• The 1227/1760 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24132 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.
