How the C4024-K30V model number is decoded

SKF lists C 4024 K30V in the dimension series 40 CARB toroidal roller bearings: the toroidal roller profile both follows tolerates angular misalignment and lets the inner ring slide axially inside the outer ring, giving free axial displacement at the non-locating position. In C 4024 K30V the 40 dimension series fixes the 180 mm OD and 60 mm width around the 120 mm bore (code 24 × 5); the suffix K30V then selects the tapered 1:30 bore for withdrawal (AH) sleeve mounting, full-complement V execution (no cage). The K30 suffix gives a 1:30 tapered 120 mm bore, mounted on a withdrawal (AH) sleeve so the bearing can be driven up to the specified clearance. The same size is listed in both bore executions, and the boundary dimensions 120×180×60 mm are identical — only the mounting method changes. Pairing rule: use the CARB bearing opposite one locating spherical or tapered bearing — never at both shaft ends — and check the locating bearing takes 100 % of the thrust, since C 4024 K30V deliberately carries none. After fitting, confirm the inner ring can be pushed axially by hand through the catalogue displacement range; a ring that will not slide means the position is locked and will preload in service.

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.
• 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.
• Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 4024 K30V must float; the two are designed to be used as a pair.
• 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 530/880 kN ratings belong to this exact execution (C 4024 K30V); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
• The 530/880 kN ratings and 5550 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.
