How the C4024-V-VE240 model number is decoded

For long shafts that grow thermally, SKF supplies C 4024 V/VE240: the toroidal rollers allow the 120 mm inner ring to displace axially without induced thrust, while still accommodating shaft deflection like a spherical bearing. Reading the code: C marks the CARB toroidal family, the first two digits (40) identify the ISO dimension series and the last two (120 mm (slash-size)) 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. Float capacity is a selection criterion: the catalogue lists the permissible axial displacement (s) for the 60 mm wide set; size the free-end housing so thermal growth stays within it, not just inside the overall width. 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 60 mm wide cavity does not fill itself.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 120 mm bore, shaft expansion is already measurable: calculate the required float inside the 60 mm wide bearing rather than assuming the free-end clearance is "enough" at operating temperature.
• The quoted 430/640 kN ratings belong to this exact execution (C 4024 V/VE240); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
• Do not block the axial displacement in the drawing: housing covers, labyrinth rings and snap rings must leave the catalogue float (s) free, or the bearing silently becomes a poorly located fixed bearing.
• 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.
• Never use C 4024 V/VE240 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.
• The 430/640 kN ratings and 5050 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.
