How the 24152-CCK30-W33 model number is decoded

24152-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 24152-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. On the SKF nameplate, 24152-cck30-w33 follows the ISO 15 convention: 2 for the spherical roller type, 41 for the dimension series 41 (medium OD, maximum width), final digits 52 for the 260 mm bore. 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. Speed planning uses two different ceilings: 670 r/min thermal reference and 950 r/min mechanical limiting speed. Because driving up the 1:30 taper consumes radial clearance, K30 executions are commonly ordered with C3 initial clearance so the residual running clearance after mounting matches the cylindrical-bore 24152-cc-w33 on an interference seat.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 260 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 260 mm bore (440×180 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 950 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 180 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24152-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.
• Catalogue reference speed and limiting speed are different limits: the 670 r/min reference is a thermal criterion under load, while the 950 r/min limiting value is the mechanical ceiling — observe both.
• The 3086/4800 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24152 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.
