How the 24156-CCK30-W33 model number is decoded

SKF lists SKF 24156 CCK30/W33 as the adapter-sleeve execution in the 24100-series range: a 280 mm nominal-bore spherical roller bearing whose 1:30 tapered inner ring is driven up a sleeve, with 460 mm OD and 180 mm width to the ISO 15 envelope. Numbering ties the bearing to its envelope: 24156-cck30-w33 means spherical-roller type, dimension series 41, 280 mm bore — which is why the 460×180 mm outline swaps dimensionally with other ISO 15 bearings of the same code. 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 90.0 mm radial section height ((460−280)/2) and 130000 g catalogue mass frame a 280 mm bore bearing rated at 3183 kN C — roughly 11.37 kN of dynamic capacity per millimetre of bore before application factors. At 280 mm bore, dismount after service is by KM locknut reversal or a hydraulic nut on larger sizes; oil-injection grooves on the bigger sleeves let pressurised oil float the 24156-cck30-w33 off the taper without scoring either surface.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 280 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 280 mm bore (460×180 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 900 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.
• 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 use the tapered-bore CCK30/K30 variant's drive-up figures on this cylindrical-bore 24156-cck30-w33; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
• The 3183/5100 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24156 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.
