How the 24136 model number is decoded
For a 180 mm shaft carrying heavy radial load with misalignment or deflection, SKF lists 24136 under catalogue execution 24136 CC/W33: two barrel-roller rows on a sphered outer raceway. The code breaks down as type digit 2 (double-row spherical roller), dimension series 41 (dimension series 41 (medium OD, maximum width)), and bore code 36 = 180 mm; dimensions 180×300×118 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. Catalogue mass 34500 g for the 180×300×118 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 mounting, swing the outer ring to confirm free self-alignment: the 24136 should tilt through its full catalogue misalignment range without binding; a stiff joint signals a cocked seat or shoulder interference.
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
- 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 24136 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 1449/2160 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- Shaft and housing fillets must clear the bearing chamfer so the 118 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- The 1449/2160 kN ratings are SKF catalogue values for this exact execution (24136 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 24136 (cylindrical bore as listed, tapered-bore 24136 CCK30/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 24136 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 24136?
The 24136 CC/W33 is a double-row spherical roller bearing with 180 mm 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: basic dynamic load rating C 1449 kN, C0 2160 kN, fatigue load limit Pu 196 kN, reference speed 1,100 r/min, limiting speed 1,600 r/min, mass about 34500 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 24136 bore code work?
The last two digits of 24136 are bore code 36, so 36 × 5 = 180 mm bore. The 300 mm OD and 118 mm width come from the ISO 15 dimension-series plan (dimension series 41 (medium OD, maximum width)), shared with other spherical roller bearings of the same code.
What does the CC/W33 suffix mean on 24136?
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 24136 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 24136K30 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 24136 listed here seats directly on a machined journal.
