How the 24130-CCK30-W33 model number is decoded
Ordering number SKF 24130 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 150×250×100 mm ISO 15 outline as its cylindrical-bore counterpart. Numbering ties the bearing to its envelope: 24130-cck30-w33 means spherical-roller type, dimension series 41, 150 mm bore — which is why the 250×100 mm outline swaps dimensionally with other ISO 15 bearings of the same code. Note that K30 means the 1:30 taper used on dimension series 40/41; the more common K means 1:12. 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 21000 g for the 150×250×100 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. Over-driving the 24130-cck30-w33 up its sleeve pinches radial clearance below the residual minimum and can crack the inner ring in service; under-driving leaves the sleeve seat loose, so the ring creeps and frets the sleeve — measure, do not estimate.
Typical equipment & failure modes
Common applications
- large dredger and marine winch drums
- steel-plant continuous-caster segments
- heavy crusher and screen shafts mounted and dismounted with hydraulic nuts
- long through-shafts in conveyors, where a sleeve seat avoids a precision journal
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
- fretting corrosion and sleeve-seat scoring when drive-up is insufficient and the tapered inner ring creeps on the adapter sleeve
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- seal-lip wear and grease purge loss when an open bearing is run without functioning housing seals
Selection pitfalls — read before you substitute
- At 150 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 150 mm bore (250×100 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 2,000 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
- Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24130-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 adapter sleeve is selected by actual shaft diameter, not by the 150 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24130-cck30-w33 with different sleeves.
- Catalogue reference speed and limiting speed are different limits: the 1,400 r/min reference is a thermal criterion under load, while the 2,000 r/min limiting value is the mechanical ceiling — observe both.
- The 1054/1530 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24130 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 24130-cck30-w33?
The SKF 24130 CCK30/W33 is a double-row spherical roller bearing with a 1:30 tapered bore, 150 mm nominal bore, 250 mm outer diameter and 100 mm width (5.906 × 9.843 × 3.937 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 1054 kN, C0 1530 kN, Pu 146 kN, reference speed 1,400 r/min, limiting speed 2,000 r/min, mass about 21000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K30 suffix mean on 24130-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 24130-cck30-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 150 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 24130-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 24130-cck30-w33 and 24130-cc-w33?
They share the ISO 15 envelope and the same 1054/1530 kN ratings, but 24130-cck30-w33 has the 1:30 tapered bore for sleeve mounting on a plain shaft, while 24130-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.
