How the 24192 model number is decoded
For a 460 mm shaft carrying heavy radial load with misalignment or deflection, SKF lists 24192 under catalogue execution 24192 ECA/W33: two barrel-roller rows on a sphered outer raceway. Numbering ties the bearing to its envelope: 24192 means spherical-roller type, dimension series 41, 460 mm bore — which is why the 760×300 mm outline swaps dimensionally with other ISO 15 bearings of the same code. CA executions here use a machined brass cage (ECA enhanced geometry) rather than pressed steel; specialist suffixes change the bearing materially and must be quoted in full, and the K/CCK tapered-bore variant is a separate order number. The 150.0 mm radial section height ((760−460)/2) and 560000 g catalogue mass frame a 460 mm bore bearing rated at 8608 kN C — roughly 18.71 kN of dynamic capacity per millimetre of bore before application factors. Spherical roller bearings are routinely specified with C3 clearance because the tight inner-ring fit and inner/outer temperature gradient eat into the CN running clearance — check the residual clearance after mounting with feeler gauges.
Typical equipment & failure modes
Common applications
- wind-turbine main shaft support
- heavy rolling-mill work-roll chocks
- large dredger and marine winch drums
- steel-plant continuous-caster segments
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 460 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 460 mm bore (760×300 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 430 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
- Shaft and housing fillets must clear the bearing chamfer so the 300 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- Never use the tapered-bore CCK30/K30 variant's drive-up figures on this cylindrical-bore 24192; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 8608/14600 kN ratings are SKF catalogue values for this exact execution (24192 ECA/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 24192 (cylindrical bore as listed, tapered-bore 24192 CCK30/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 24192 ECA/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 24192?
The 24192 ECA/W33 is a double-row spherical roller bearing with 460 mm bore, 760 mm outer diameter and 300 mm width (18.11 × 29.921 × 11.811 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 8608 kN, C0 14600 kN, fatigue load limit Pu 1000 kN, reference speed 280 r/min, limiting speed 430 r/min, mass about 560000 g. It is an open, self-aligning bearing with a one-piece machined brass cage guided on the inner ring (CA design).
How does the 24192 bore code work?
The last two digits of 24192 are bore code 92, so 92 × 5 = 460 mm bore. The 760 mm OD and 300 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 ECA/W33 suffix mean on 24192?
The suffix ECA/W33 reads ECA — the enhanced version of the CA design with optimized internal geometry, plus W33 (annular groove and three lubrication holes in the outer ring for relubrication); CCK30/W33 is the 1:30 tapered-bore counterpart.
Can 24192 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 24192K30 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 24192 listed here seats directly on a machined journal.
