How the 24026-CCK30-W33 model number is decoded
Ordering number SKF 24026 CCK30/W33 in SKF catalogue PUB BU/P1 17000 is a double-row spherical roller bearing with a tapered bore (1:30), intended for an H-series adapter sleeve or AH withdrawal sleeve, with two pressed-steel cages with a floating guide ring and the same 130×200×69 mm ISO 15 outline as its cylindrical-bore counterpart. 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 130 mm bore; the 200 mm OD and 69 mm width follow the ISO 15 general plan. 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. The 81.5 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.43 C0/C balance shows this execution is tuned to heavy radial-plus-axial duty with misalignment tolerance. At 130 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 24026-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
- long through-shafts in conveyors, where a sleeve seat avoids a precision journal
- stepped shafts fitted with withdrawal sleeves against a fixed shoulder
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
- sleeve seizure and shaft seat damage from omitting the anti-seize film between withdrawal sleeve and journal before drive-up
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- hard-particle indentation of the raceway in unfiltered oil or contaminated grease systems
Selection pitfalls — read before you substitute
- At 130 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 130 mm bore (200×69 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.
- A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 69 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
- Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24026-cck30-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 69 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- The 569/815 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24026 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 24026-cck30-w33?
The SKF 24026 CCK30/W33 is a double-row spherical roller bearing with a 1:30 tapered bore, 130 mm nominal bore, 200 mm outer diameter and 69 mm width (5.118 × 7.874 × 2.717 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 569 kN, C0 815 kN, Pu 81.5 kN, reference speed 2,000 r/min, limiting speed 3,000 r/min, mass about 8650 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K30 suffix mean on 24026-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 24026-cck30-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 130 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 24026-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 24026-cck30-w33 and 24026-cc-w33?
They share the ISO 15 envelope and the same 569/815 kN ratings, but 24026-cck30-w33 has the 1:30 tapered bore for sleeve mounting on a plain shaft, while 24026-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.
