How the C3024-V model number is decoded
C 3024 V belongs to the CARB family — compact aligning roller bearings: envelope 120×180×46 mm, radial rating 430/640 kN C/C0, and no axial-locating function by design. Reading the code: C marks the CARB toroidal family, the first two digits (30) identify the ISO dimension series and the last two (24) encode the 120 mm bore; suffixes describe bore and execution. The open execution relies on the housing seals and lubrication system, fed through groove/hole features on the large sizes. Explorer-class heat treatment and the crowned roller profile keep edge stress down when the 120 mm shaft deflects; no reference speed is listed and the limiting speed is 1,400 r/min. No thermal reference speed is listed for this full-complement execution; the mechanical limiting speed is 1,400 r/min. The full-complement V executions carry more load but list no thermal reference speed; the steel-caged executions run faster and cooler at light load. Open executions accept relubrication — route it through the outer-ring groove on sizes that have one and purge stale grease at service intervals. Grease through the annular groove features where provided; on open executions feed lubricant past the long roller set at assembly, since the 46 mm wide cavity does not fill itself.
Typical equipment & failure modes
Common applications
- heavy industrial gearbox layshafts used as the non-locating position
- winder and reel drums in paper and steel strip plants
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- continuous-caster guide rolls and slab-caster segments under heat growth
Known failure patterns
- roller-end and flange smearing after lubricant starvation at the long roller contacts
- roller skew and cage damage after the bearing is clamped solid between shaft and housing shoulders
- brass cage pocket wear under marginal lubrication in the large-bore M/MB executions
- brinelling of washer raceways from impact or mounting force applied through the rolling elements
- grease churning and overheating when a high-speed thrust position is over-packed
Selection pitfalls — read before you substitute
- At 120 mm bore, shaft expansion is already measurable: calculate the required float inside the 46 mm wide bearing rather than assuming the free-end clearance is "enough" at operating temperature.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 3024 V must float; the two are designed to be used as a pair.
- Never use C 3024 V as the locating bearing: it carries no axial load by design — the arrangement needs a separate locating spherical, tapered or angular bearing facing the thrust.
- Reference and limiting speeds are different limits: the catalogue lists no thermal reference speed for this full-complement/sealed execution, the limiting value is the mechanical ceiling; observe the reference under load unless the arrangement calculation says otherwise.
- The quoted 430/640 kN ratings belong to this exact execution (C 3024 V); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
- The 430/640 kN ratings and 4100 g mass are SKF catalogue values transcribed from ch. 10.1 of PUB BU/P1 17000 (PDF table page 862); mounting data — axial displacement (s) and seating details — appears in the running text because the structured record carries the boundary envelope only.
Frequently asked questions
Is the C 3024 V sealed?
No, it is an open execution relying on the housing seals; the full-complement V design has no thermal reference speed in the catalogue.
What fails first on a misapplied CARB bearing?
Blocking the designed axial float — clamping the free end or locating both shaft ends — turns thermal growth into edge loading and spalls the toroidal raceways. Cage damage and ordinary fatigue follow overload or dry running.
Which dimensions does the C 3024 V have?
A C 3024 V measures 120 mm bore × 180 mm outside diameter × 46 mm width (4.724 × 7.087 × 1.811 in). From SKF catalogue PUB BU/P1 17000: dynamic C 430 kN, static C0 640 kN, fatigue limit Pu 65.5 kN, limiting speed 1,400 r/min, no reference speed listed, mass about 4100 g.
What does C 3024 V mean in SKF part numbering?
C marks CARB; 30 the dimension series; the size code gives 120 mm bore; V is the execution (cylindrical bore for direct shaft fitting, full-complement V execution (no cage)). The envelope follows ISO 15 and matches spherical roller bearing outlines, but the functions differ.
