How the 24060-CCK30-W33 model number is decoded
The SKF 24060 CCK30/W33 is a 300×460×160 mm spherical roller bearing with a 1:30 tapered bore — SKF catalogue execution for sleeve mounting on a 300 mm plain shaft, retaining the double-row self-aligning barrel-roller design. On the SKF nameplate, 24060-cck30-w33 follows the ISO 15 convention: 2 for the spherical roller type, 40 for the dimension series 40 (compact OD, maximum width), final digits 60 for the 300 mm bore. 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 110000 g for the 300×460×160 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 24060-cck30-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
Common applications
- large dredger and marine winch drums
- steel-plant continuous-caster segments
- 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 300 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 300 mm bore (460×160 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 24060-cck30-w33 and its cylindrical-bore counterpart 24060-cc-w33 share envelope and load ratings (2821/4750 kN) but are not interchangeable in a housing already fitted for direct shaft mounting — the sleeve changes the assembly stack-up.
- Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24060-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.
- 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 2821/4750 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24060 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 24060-cck30-w33?
The SKF 24060 CCK30/W33 is a double-row spherical roller bearing with a 1:30 tapered bore, 300 mm nominal bore, 460 mm outer diameter and 160 mm width (11.811 × 18.11 × 6.299 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 2821 kN, C0 4750 kN, Pu 355 kN, reference speed 850 r/min, limiting speed 1,200 r/min, mass about 110000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K30 suffix mean on 24060-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 24060-cck30-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 300 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 24060-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 24060-cck30-w33 and 24060-cc-w33?
They share the ISO 15 envelope and the same 2821/4750 kN ratings, but 24060-cck30-w33 has the 1:30 tapered bore for sleeve mounting on a plain shaft, while 24060-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.
