How the 24026 model number is decoded
Ordering number 24026 CC/W33 in SKF catalogue PUB BU/P1 17000 denotes a double-row spherical roller bearing for a 130 mm shaft, dimension series 40 (compact OD, maximum width), with open execution and two pressed-steel cages with a floating guide ring. On the SKF nameplate, 24026 follows the ISO 15 convention: 2 for the spherical roller type, 40 for the dimension series 40 (compact OD, maximum width), final digits 26 for the 130 mm bore. 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. Catalogue mass 8050 g for the 130×200×69 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. The cylindrical-bore execution here seats directly on the shaft journal; if the application calls for an adapter sleeve, order the tapered-bore 24026 CCK30/W33 variant instead and measure the drive-up or clearance reduction, not the nut torque.
Typical equipment & failure modes
Common applications
- large dredger and marine winch drums
- steel-plant continuous-caster segments
- large induced-draft fan rotors
- SAG and ball-mill drive shafts
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
- stamped-steel cage fatigue after long service in high-vibration screening duty without the VA405 execution
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- 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.
- 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.
- Open spherical roller bearings rely on the housing seals; in screening or crusher duty a failed seal lets grit into the sphered raceway and the 24026 pits long before its L10 life.
- The 569/815 kN ratings are SKF catalogue values for this exact execution (24026 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 24026 (cylindrical bore as listed, tapered-bore 24026 CCK30/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 24026 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 24026?
The 24026 CC/W33 is a double-row spherical roller bearing with 130 mm 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: basic dynamic load rating C 569 kN, C0 815 kN, fatigue load limit Pu 81.5 kN, reference speed 2,000 r/min, limiting speed 3,000 r/min, mass about 8050 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 24026 bore code work?
The last two digits of 24026 are bore code 26, so 26 × 5 = 130 mm bore. The 200 mm OD and 69 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 24026?
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 24026 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 24026K30 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 24026 listed here seats directly on a machined journal.
