How the 24148-CCK30-W33 model number is decoded

Ordering number SKF 24148 CCK30/W33 in SKF catalogue PUB BU/P1 17000 is a double-row spherical roller bearing with a tapered bore (1:30), intended for an H-series adapter sleeve or AH withdrawal sleeve, with two pressed-steel cages with a floating guide ring and the same 240×400×160 mm ISO 15 outline as its cylindrical-bore counterpart. Reading the designation: the leading 2 marks a spherical roller bearing, the 41 is the ISO 15 dimension series (dimension series 41 (medium OD, maximum width)), and the last two digits encode the 240 mm bore; the 400 mm OD and 160 mm width follow the ISO 15 general plan. 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. The 320 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.57 C0/C balance shows this execution is tuned to heavy radial-plus-axial duty with misalignment tolerance. 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 24148-cck30-w33 removable without an induction heater.

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 24100-series series at 240 mm bore (400×160 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 1,100 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 240 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24148-cck30-w33 with different sleeves.
• 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 24148-cck30-w33 with different sleeves.
• Catalogue reference speed and limiting speed are different limits: the 750 r/min reference is a thermal criterion under load, while the 1,100 r/min limiting value is the mechanical ceiling — observe both.
• The 2489/3900 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24148 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.
