How the 23048-CCK-W33 model number is decoded

In SKF catalogue PUB BU/P1 17000, 23048-cck-w33 denotes the tapered-bore version (K suffix, taper 1:12) of the 23000-series spherical roller bearing: dimensioned 240×360×92 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 30 is the ISO 15 dimension series (dimension series 30 (slim OD, extra-wide)), and the last two digits encode the 240 mm bore; the 360 mm OD and 92 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. Catalogue mass 44500 g for the 240×360×92 mm open execution covers the two pressed-steel cages with a floating guide ring; tapered-bore and sealed variants differ in mass and carry their own order numbers. After drive-up, re-check radial clearance and then swing the outer ring through its self-aligning range: the sphered raceway of the 23048-cck-w33 must still tilt ≈ 0.5–2.5° freely — a joint that binds after sleeve mounting signals excessive drive-up or a cocked sleeve.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 240 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 23000-series series at 240 mm bore (360×92 mm) is the slim-OD envelope: it buys radial space but gives up capacity against a 222-series bearing of the same bore — confirm the L10 margin before downsizing into it.
• The adapter sleeve is selected by actual shaft diameter, not by the 240 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 23048-cck-w33 with different sleeves.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 92 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• Never use the tapered-bore EK/K variant's drive-up figures on this cylindrical-bore 23048-cck-w33; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
• The 1340/2080 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 23048 CCK/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.
