How the 24032-CCK30-W33 model number is decoded
In SKF catalogue PUB BU/P1 17000, 24032-cck30-w33 denotes the tapered-bore version (K30 suffix, taper 1:30) of the 24000-series spherical roller bearing: dimensioned 160×240×80 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 40 is the ISO 15 dimension series (dimension series 40 (compact OD, maximum width)), and the last two digits encode the 160 mm bore; the 240 mm OD and 80 mm width follow the ISO 15 general plan. Reading the suffix on 24032-cck30-w33, the K30 (or EK/CCK30) element changes only the bore — 1:30 taper for sleeve mounting — while the rest of the suffix chain (CC cages with W33 groove) keeps the same internal design, cage and W33 relubrication features as the cylindrical-bore 24032-cc-w33. The 114 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.53 C0/C balance shows this execution is tuned to heavy radial-plus-axial duty with misalignment tolerance. At 160 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 24032-cck30-w33 off the taper without scoring either surface.
Typical equipment & failure modes
Common applications
- steel-plant continuous-caster segments
- large induced-draft fan rotors
- stepped shafts fitted with withdrawal sleeves against a fixed shoulder
- fan and pulley shafts that need periodic bearing removal in the field
Known failure patterns
- raceway fatigue spalling of the sphered outer raceway after extended service above the catalogue L10 rating
- inner-ring raceway spalling from edge loading when misalignment exceeds the self-aligning recovery range
- inner-ring circumferential cracking after over-drive on the tapered seat removes too much radial clearance and the bearing runs preloaded
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- smearing on the roller-raceway contact during skid starts below the minimum load
Selection pitfalls — read before you substitute
- At 160 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 160 mm bore (240×80 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 160 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24032-cck30-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 80 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
- The 24032-cck30-w33 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 783/1200 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- The 783/1200 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24032 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.
Frequently asked questions
What are the dimensions and catalogue data of 24032-cck30-w33?
The SKF 24032 CCK30/W33 is a double-row spherical roller bearing with a 1:30 tapered bore, 160 mm nominal bore, 240 mm outer diameter and 80 mm width (6.299 × 9.449 × 3.15 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 783 kN, C0 1200 kN, Pu 114 kN, reference speed 1,700 r/min, limiting speed 2,400 r/min, mass about 15000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K30 suffix mean on 24032-cck30-w33?
K30 (written CCK30/W33 in the CC execution) marks the 1:30 tapered bore for sleeve mounting. The bearing seats on an H-series adapter sleeve with a KM locknut and MB lock washer (plain shaft, h9 tolerance), or on an AH withdrawal sleeve against a shaft shoulder.
Which adapter sleeve fits the 24032-cck30-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 160 mm nominal bore: SKF H-sleeve numbers each cover a small shaft-diameter range and are width-series specific (H39/H30/H31/H32 matching dimension series 39/40/31/32), and each kit bundles the sleeve, KM locknut and MB lock washer. For shoulder locations use an AH withdrawal sleeve instead. Confirm the sleeve number against the SKF catalogue PUB BU/P1 17000 mounting tables for your shaft size.
How is the 24032-cck30-w33 driven up and checked?
Mounting is controlled by radial-clearance reduction or axial drive-up distance from the SKF catalogue tables for the 1:30 taper, never by locknut torque. Measure clearance with feeler gauges before and after tightening the KM nut, stop at the tabulated decrease, and lock the MB washer tab. Over-drive removes too much clearance (inner-ring cracking risk); under-drive lets the sleeve creep and fret.
What is the difference between 24032-cck30-w33 and 24032-cc-w33?
They share the ISO 15 envelope and the same 783/1200 kN ratings, but 24032-cck30-w33 has the 1:30 tapered bore for sleeve mounting on a plain shaft, while 24032-cc-w33 has a cylindrical bore for direct mounting on a machined interference journal (typically m6 with H7 housing). They are separate order numbers, not interchangeable in the same shaft arrangement.
