How the 24160-CCK30-W33 model number is decoded

For sleeve mounting on a 300 mm shaft, SKF order number SKF 24160 CCK30/W33 is the 1:30 tapered-bore spherical roller bearing in the 24100-series family (dimension series 41 (medium OD, maximum width)); the cylindrical-bore equivalent is a separate order number, 24160-cc-w33. 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 300 mm bore; the 500 mm OD and 200 mm width follow the ISO 15 general plan. Reading the suffix on 24160-cck30-w33, the K30 (or EK/CCK30) element changes only the bore — 1:30 taper for sleeve mounting — while the rest of the suffix chain (CC cages with W33 groove) keeps the same internal design, cage and W33 relubrication features as the cylindrical-bore 24160-cc-w33. At 560 r/min reference speed the 100.0 mm-section 24160-cck30-w33 is governed thermally by lubricant flow through the W33 groove and the two-row roller complement; grease or oil selection should be made against that value, with 800 r/min as the mechanical ceiling. On an H adapter sleeve the 300 mm shaft seat only needs an h9 plain journal; slide the sleeve into the 24160-cck30-w33 inner ring, tighten the KM nut against the MB washer until the catalogue clearance-reduction value is reached, then lock the washer tab.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 300 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 300 mm bore (500×200 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 800 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
• The 24160-cck30-w33 and its cylindrical-bore counterpart 24160-cc-w33 share envelope and load ratings (3876/6300 kN) but are not interchangeable in a housing already fitted for direct shaft mounting — the sleeve changes the assembly stack-up.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 200 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• Shaft and housing fillets must clear the bearing chamfer so the 200 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
• The 3876/6300 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24160 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.
