How the 24036-CCK30-W33 model number is decoded

Ordering number SKF 24036 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 180×280×100 mm ISO 15 outline as its cylindrical-bore counterpart. The code breaks down as type digit 2 (double-row spherical roller), dimension series 40 (dimension series 40 (compact OD, maximum width)), and bore code 36 = 180 mm; dimensions 180×280×100 mm therefore match the ISO 15 envelope. Sleeve mounting is why the K30 execution exists: a plain h9-tolerance shaft is enough because the adapter sleeve supplies the precision seat, and the bearing is removable without pulling over an interference journal — a separate order number from the cylindrical-bore bearing, never a field conversion. At 1,500 r/min reference speed the 50.0 mm-section 24036-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 2,200 r/min as the mechanical ceiling. Over-driving the 24036-cck30-w33 up its sleeve pinches radial clearance below the residual minimum and can crack the inner ring in service; under-driving leaves the sleeve seat loose, so the ring creeps and frets the sleeve — measure, do not estimate.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 180 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 24000-series series at 180 mm bore (280×100 mm) packs maximum roller length into the smallest OD envelope — very high C0 for its size but the lowest speed ceiling; never swap it for a wider-OD 231 bearing without re-checking the housing bore and the speed margin.
• The adapter sleeve is selected by actual shaft diameter, not by the 180 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24036-cck30-w33 with different sleeves.
• Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24036-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 1,500 r/min reference is a thermal criterion under load, while the 2,200 r/min limiting value is the mechanical ceiling — observe both.
• The 1134/1730 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24036 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.
