How the C4024-2CS5V-GEM9 model number is decoded

C 4024-2CS5V/GEM9 is the dimension series 40 CARB toroidal roller bearings member of the CARB range: 120 mm bore, 180 mm OD, 60 mm width, with the asymmetrical-looking toroidal roller set that defines the CARB principle. In C 4024-2CS5V/GEM9 the 40 dimension series fixes the 180 mm OD and 60 mm width around the 120 mm bore (the bore is written directly after the slash (no bore code)); the suffix 2CS5V/GEM9 then selects the cylindrical bore for direct shaft fitting, 2CS5V/GEM9 sealed full-complement execution with annular groove. The cylindrical 120 mm bore mounts directly on a machined seat; the outer ring takes a loose housing fit so the bearing can float axially. The same size is listed in both bore executions, and the boundary dimensions 120×180×60 mm are identical — only the mounting method changes. 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. Sealed executions arrive greased for life: do not wash out the factory fill, and mount seals-clear of the housing shoulder edges. 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.
• Never use C 4024-2CS5V/GEM9 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.
• Tapered-bore K executions mount on adapter sleeves (1:12) and K30 on withdrawal sleeves (1:30) — the 120 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
• 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 4024-2CS5V/GEM9); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
• The 430/640 kN ratings and 5100 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.
