How the C4034-K30V-AH24034 model number is decoded
Housing side of C4034-K30V-AH24034 is conventional: a 260 mm H7 bore takes the CARB outer ring, which is free to slide axially in the housing — the toroidal raceway handles the misalignment and the sleeve side handles the location on the 160 mm shaft.For a 160 mm shaft SKF lists C4034-K30V-AH24034 as the complete unit: CARB bearing C 4034 K30V plus withdrawal sleeve AH 24034, one catalogue entry covering both components.The code breaks into bearing C 4034 K30V and withdrawal sleeve AH 24034: C marks the CARB type, the digit group the 170 mm bore size, the following letters the cage/tolerance execution, and the sleeve designation its own SKF number — sleeve and bearing are keyed to each other and must be ordered as the pair C4034-K30V-AH24034. Withdrawal sleeve AH 24034: at this size the sleeve is pulled onto the 160 mm seat (hydraulic assistance is standard) and its taper sets the interference into the 170 mm bearing bore — dismounting uses the sleeve's withdrawal thread, protecting shaft and bearing raceways. Speed note: no catalogue speed rating exists for this size class the permissible speed of the unit is bounded by the CARB bearing's own catalogue values and by the sleeve-seat interface; sleeve-mounted units run marginally cooler-balanced because the sleeve adds a thermal resistance at the 160 mm seat. Dismounting uses the withdrawal thread on AH 24034: pull the sleeve back along its cone with the dedicated withdrawal nut or hydraulic tool — the CARB bearing and sleeve come off the 160 mm seat as one piece and the seat stays undamaged.
Typical equipment & failure modes
Common applications
- 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
- winder and reel drums in paper and steel strip plants
- continuous-caster guide rolls and slab-caster segments under heat growth
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
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
- sleeve creep on the shaft seat when the sleeve was not driven to its marked travel or clearance
- sleeve creep on the shaft seat when the sleeve was not driven to its marked travel or clearance
Selection pitfalls — read before you substitute
- Never set C4034-K30V-AH24034 by locknut torque or "feel": the withdrawal sleeve travel defines the clearance of the 170 mm CARB bearing — measure residual radial clearance during mounting, in steps.
- Protect the 160 mm seat: sleeve bore corrosion or seat ovality shows up later as sleeve creep and fretting; inspect and measure the seat at every dismounting of C4034-K30V-AH24034.
- Do not run C4034-K30V-AH24034 as a locating bearing: the CARB raceway is toroidal and the unit is designed to float axially; blocking it against a shoulder preloads the rollers and ends in thermal failure.
- The 1140/1860 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 4034 K30V + AH 24034 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 C4034-K30V-AH24034?
The unit is CARB bearing C 4034 K30V on withdrawal sleeve AH 24034, fitting a 160 mm shaft (6.299 in), housing bore 260 mm, bearing width 90 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1140 kN, C0 1860 kN, fatigue load limit Pu 173 kN, combined mass about 20.0 kg. The catalogue lists no speed ratings for this size class — permissible speed follows the application heat balance.
Why does C4034-K30V-AH24034 list a 160 mm shaft size when the bearing bore is 170 mm?
The sleeve takes up the difference: the withdrawal sleeve AH 24034 has a tapered outside that engages the bearing's 170 mm tapered bore and a cylindrical bore that seats on the 160 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C4034-K30V-AH24034 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 4034 K30V and the sleeve AH 24034 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 C4034-K30V-AH24034 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C4034-K30V-AH24034 set at mounting?
By sleeve travel: the withdrawal sleeve AH 24034 is driven or pressed to a marked travel on the 160 mm seat, which sets the interference into the 170 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
