How the 23192-CAK-W33 model number is decoded

In SKF catalogue PUB BU/P1 17000, 23192-cak-w33 denotes the tapered-bore version (K suffix, taper 1:12) of the 23100-series spherical roller bearing: dimensioned 460×760×240 mm, it seats on an adapter or withdrawal sleeve rather than directly on a machined journal. Reading the designation: the leading 2 marks a spherical roller bearing, the 31 is the ISO 15 dimension series (dimension series 31 (medium OD, wide)), and the last two digits encode the 460 mm bore; the 760 mm OD and 240 mm width follow the ISO 15 general plan. Note that K means 1:12 taper; the rarer K30 suffix means 1:30. 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. The 680 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.60 C0/C balance shows this execution is tuned to heavy radial-plus-axial duty with misalignment tolerance. Because driving up the 1:12 taper consumes radial clearance, K executions are commonly ordered with C3 initial clearance so the residual running clearance after mounting matches the cylindrical-bore 23192-cak-w33 on an interference seat.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 460 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 23100-series series at 460 mm bore (760×240 mm) is the medium-OD wide envelope for heavy continuous duty; it is wider than a 222 bearing in the same OD class, so housing width and spacer stack must be re-checked before substitution.
• The adapter sleeve is selected by actual shaft diameter, not by the 460 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 23192-cak-w33 with different sleeves.
• Never apply the drive-up or clearance-reduction figures for this 1:12 tapered 23192-cak-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.
• The self-aligning feature is not a license to ignore alignment: beyond ≈ 0.5–2.5° (series-dependent) the edge loading eats the fatigue margin, and seal drag grows as the rings tilt.
• The 6760/10800 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 23192 CAK/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.
