How the 24140-CCK30-W33 model number is decoded

For sleeve mounting on a 200 mm shaft, SKF order number SKF 24140 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, 24140-cc-w33. The code breaks down as type digit 2 (double-row spherical roller), dimension series 41 (dimension series 41 (medium OD, maximum width)), and bore code 40 = 200 mm; dimensions 200×340×140 mm therefore match the ISO 15 envelope. The K30 in the designation marks the 1:30 tapered bore: SKF mounts it on an H-series adapter sleeve (with KM locknut and MB lock washer) on a plain commercial-grade shaft, or on an AH withdrawal sleeve where the bearing must abut a shaft shoulder. Catalogue mass 57500 g for the 200×340×140 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. At 200 mm bore, dismount after service is by KM locknut reversal or a hydraulic nut on larger sizes; oil-injection grooves on the bigger sleeves let pressurised oil float the 24140-cck30-w33 off the taper without scoring either surface.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 200 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 200 mm bore (340×140 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 1,400 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 140 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• The adapter sleeve is selected by actual shaft diameter, not by the 200 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24140-cck30-w33 with different sleeves.
• The 57500 g mass and 140 mm width mean abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the outer ring and concentrates load on one roller row of 24140-cck30-w33.
• The 1865/2800 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24140 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.
