How the C4024-K30V-VE240-AH24024 model number is decoded
For a 115 mm shaft SKF lists C4024-K30V-VE240-AH24024 as the complete unit: CARB bearing C 4024 K30V/VE240 plus withdrawal sleeve AH 24024, one catalogue entry covering both components.Digit by digit, C4024-K30V-VE240-AH24024 = CARB bearing C 4024 K30V/VE240 (120 mm bore, 180 mm OD, 60 mm width) + withdrawal sleeve AH 24024 for the 115 mm cylindrical shaft seat; cage and tolerance letters stay with the bearing half of the designation. Combined mass of the unit — bearing C 4024 K30V/VE240 plus sleeve AH 24024 — is about 6 kg; plan lifting gear and heating equipment around the assembly, not the bare bearing. Dividing C 430 kN by the 120 mm bore gives 3.58 kN per millimetre of journal — compare this density against neighbouring CARB sizes when the 115 mm seat is fixed and the life requirement is not. Dismounting uses the withdrawal thread on AH 24024: pull the sleeve back along its cone with the dedicated withdrawal nut or hydraulic tool — the CARB bearing and sleeve come off the 115 mm seat as one piece and the seat stays undamaged. Spare-parts note: order C4024-K30V-VE240-AH24024 as the unit; a bare C 4024 K30V/VE240 plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.
Typical equipment & failure modes
Common applications
- vibrating screen exciters fitted with the VE240 tolerance execution
- long fan and kiln main shafts where the free end must float without thrust load
- heavy industrial gearbox layshafts used as the non-locating position
- vibrating screen exciters fitted with the VE240 tolerance execution
Known failure patterns
- misalignment edge loading when the housing bore is out of square with the shaft seat
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
- misalignment edge loading when the housing bore is out of square with the shaft seat
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
Selection pitfalls — read before you substitute
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C4024-K30V-VE240-AH24024 and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C4024-K30V-VE240-AH24024 unit — replace the sleeve with the bearing.
- Sleeve and bearing are a matched taper pair: never fit sleeve AH 24024 onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- The 430/640 kN ratings are SKF catalogue 17000 values for the CARB bearing; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification.
- Quote the full unit designation SKF C 4024 K30V/VE240 + AH 24024 when purchasing — bearing and sleeve execution letters are part of the order number and define the matched taper pair.
Frequently asked questions
What are the dimensions and catalogue data of C4024-K30V-VE240-AH24024?
The unit is CARB bearing C 4024 K30V/VE240 on withdrawal sleeve AH 24024, fitting a 115 mm shaft (4.528 in), housing bore 180 mm, bearing width 60 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 430 kN, C0 640 kN, fatigue load limit Pu 65.5 kN, combined mass about 5.7 kg. The catalogue lists no speed ratings for this size class — permissible speed follows the application heat balance.
Why does C4024-K30V-VE240-AH24024 list a 115 mm shaft size when the bearing bore is 120 mm?
The sleeve takes up the difference: the withdrawal sleeve AH 24024 has a tapered outside that engages the bearing's 120 mm tapered bore and a cylindrical bore that seats on the 115 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C4024-K30V-VE240-AH24024 a locating or non-locating bearing?
Non-locating. The CARB toroidal roller bearing is designed as the free end of the shaft: its raceway geometry tolerates misalignment and allows axial float, while a separate locating bearing (typically a spherical roller or paired taper) takes the thrust. The sleeve does not change this function.
Can I buy the bearing C 4024 K30V/VE240 and the sleeve AH 24024 separately?
The components are catalogued separately, but the taper pair is matched — the sleeve seat and the bearing bore are manufactured to the same execution. Ordering the unit C4024-K30V-VE240-AH24024 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C4024-K30V-VE240-AH24024 set at mounting?
By sleeve travel: the withdrawal sleeve AH 24024 is driven or pressed to a marked travel on the 115 mm seat, which sets the interference into the 120 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
