How the 24072 model number is decoded
24072 CC/W33 belongs to the SKF spherical roller range — the 360 mm bore entry in the 24000-series series (dimension series 40 (compact OD, maximum width)), dimensioned 540 mm OD and 180 mm wide. The code breaks down as type digit 2 (double-row spherical roller), dimension series 40 (dimension series 40 (compact OD, maximum width)), and bore code 72 = 360 mm; dimensions 360×540×180 mm therefore match the ISO 15 envelope. SKF basic executions here are CC/W33; specialist suffixes change the bearing materially — VA405 for vibrating screens (C4 clearance, surface-hardened cage), 2CS5 for the sealed variant — and must be quoted in full when ordering. Speed planning uses two different ceilings: 700 r/min thermal reference and 1,000 r/min mechanical limiting speed. A 360 mm rotating inner ring usually runs m6 on the shaft with H7 in the housing; for vibrating-screen duty the outer ring is instead held tight and the shaft seat loosened — follow the screen builder's fit schedule.
Typical equipment & failure modes
Common applications
- large mining crusher main shafts
- wind-turbine main shaft support
- heavy rolling-mill work-roll chocks
- large dredger and marine winch drums
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
- cage pocket wear or fracture from roller skew at insufficient minimum load or rapid acceleration
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- false brinelling on standby machines exposed to external vibration
Selection pitfalls — read before you substitute
- At 360 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 360 mm bore (540×180 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 24072 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 3705/6550 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.

- The 3705/6550 kN ratings are SKF catalogue values for this exact execution (24072 CC/W33); SKF can revise internal geometry without changing the order number, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the specification and re-verify for critical drives.
- SKF lists several executions of 24072 (cylindrical bore as listed, tapered-bore 24072 CCK30/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 24072 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 24072?
The 24072 CC/W33 is a double-row spherical roller bearing with 360 mm bore, 540 mm outer diameter and 180 mm width (14.173 × 21.26 × 7.087 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 3705 kN, C0 6550 kN, fatigue load limit Pu 490 kN, reference speed 700 r/min, limiting speed 1,000 r/min, mass about 145000 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 24072 bore code work?
The last two digits of 24072 are bore code 72, so 72 × 5 = 360 mm bore. The 540 mm OD and 180 mm width come from the ISO 15 dimension-series plan (dimension series 40 (compact OD, maximum width)), shared with other spherical roller bearings of the same code.
What does the CC/W33 suffix mean on 24072?
CC denotes two pressed-steel cages with a floating guide ring between the roller rows, and W33 adds an annular groove plus three lubrication holes in the outer ring for relubrication. In dimension series 40/41 the tapered-bore counterpart carries CCK30/W33 with a 1:30 taper.
Can 24072 accommodate misalignment and axial load?
Yes on both counts. The sphered outer raceway lets the bearing self-align ≈ 0.5–2.5° depending on series, absorbing shaft deflection and housing-seat errors. The two barrel-roller rows also carry bidirectional axial load in addition to heavy radial load — this is the key difference from cylindrical roller bearings, which take no axial load.
When should the tapered-bore 24072K30 variant be used instead?
Choose the K30 (1:30 tapered bore) variant when the bearing must seat on an adapter or withdrawal sleeve — typical for long shafts, frequent dismounting, or stepped shafts where machining a precision journal is impractical. Sleeve mounting requires measuring clearance reduction or axial drive-up, not nut torque. The cylindrical-bore 24072 listed here seats directly on a machined journal.
