How the 24096-ECAK30-W33 model number is decoded

In SKF catalogue PUB BU/P1 17000, 24096-ecak30-w33 denotes the tapered-bore version (K30 suffix, taper 1:30) of the 24000-series spherical roller bearing: dimensioned 480×700×218 mm, it seats on an adapter or withdrawal sleeve rather than directly on a machined journal. Digit by digit, 24096-ecak30-w33 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 40, and bore reference 96 resolving to 480 mm; 700 mm OD and 218 mm width are the matching ISO 15 boundary values. 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. At 450 r/min reference speed the 110.0 mm-section 24096-ecak30-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 750 r/min as the mechanical ceiling. Over-driving the 24096-ecak30-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 480 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 480 mm bore (700×218 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 480 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24096-ecak30-w33 with different sleeves.
• Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24096-ecak30-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.
• Shaft and housing fillets must clear the bearing chamfer so the 218 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
• The 5524/10400 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24096 ECAK30/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.
