How the 24136-CCK30-W33 model number is decoded
SKF lists SKF 24136 CCK30/W33 as the adapter-sleeve execution in the 24100-series range: a 180 mm nominal-bore spherical roller bearing whose 1:30 tapered inner ring is driven up a sleeve, with 300 mm OD and 118 mm width to the ISO 15 envelope. Digit by digit, 24136-cck30-w33 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 41, and bore reference 36 resolving to 180 mm; 300 mm OD and 118 mm width are the matching ISO 15 boundary values. 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. Speed planning uses two different ceilings: 1,100 r/min thermal reference and 1,600 r/min mechanical limiting speed. On an H adapter sleeve the 180 mm shaft seat only needs an h9 plain journal; slide the sleeve into the 24136-cck30-w33 inner ring, tighten the KM nut against the MB washer until the catalogue clearance-reduction value is reached, then lock the washer tab.
Typical equipment & failure modes
Common applications
- large mining crusher main shafts
- wind-turbine main shaft support
- 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
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- At 180 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 180 mm bore (300×118 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 1,600 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
- The adapter sleeve is selected by actual shaft diameter, not by the 180 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24136-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 118 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
- The 37000 g mass and 118 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 24136-cck30-w33.
- The 1449/2160 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24136 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 24136-cck30-w33?
The SKF 24136 CCK30/W33 is a double-row spherical roller bearing with a 1:30 tapered bore, 180 mm nominal bore, 300 mm outer diameter and 118 mm width (7.087 × 11.811 × 4.646 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 1449 kN, C0 2160 kN, Pu 196 kN, reference speed 1,100 r/min, limiting speed 1,600 r/min, mass about 37000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K30 suffix mean on 24136-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 24136-cck30-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 180 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 24136-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 24136-cck30-w33 and 24136-cc-w33?
They share the ISO 15 envelope and the same 1449/2160 kN ratings, but 24136-cck30-w33 has the 1:30 tapered bore for sleeve mounting on a plain shaft, while 24136-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.
