How the C30-560-KM-AOHX30-560 model number is decoded
Spare-parts note: order C30-560-KM-AOHX30-560 as the unit; a bare C 30/560 KM plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.C30-560-KM-AOHX30-560 is a complete SKF mounting unit for the largest CARB sizes: the toroidal roller bearing C 30/560 KM on withdrawal sleeve AOHX 30/560, listed in SKF catalogue PUB BU/P1 17000 for a 530 mm shaft seat.On the SKF nameplate, C30-560-KM-AOHX30-560 reads as two catalogued components: the CARB bearing C 30/560 KM with its 560 mm tapered (K) bore, and the withdrawal sleeve AOHX 30/560 whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 530 mm shaft size. Sleeve discipline for AOHX 30/560: the taper is matched to the bearing bore, the thread end is for withdrawal tooling; never interchange sleeves between bearings of the same bore size without checking the execution letters — seat length and withdrawal thread differ by execution. With a combined mass of 415.0 kg over the 530×820×195 mm principal plan, the unit replaces a machined shoulder seat — the mass difference against the bare bearing is the sleeve steel, priced into the one order number. Record the sleeve travel at mounting of C30-560-KM-AOHX30-560: the clearance set into the 560 mm bearing today is the reference for the next re-clearance check, and travel data catches seat wear on the 530 mm shaft over the years.
Typical equipment & failure modes
Common applications
- heavy industrial gearbox layshafts used as the non-locating position
- winder and reel drums in paper and steel strip plants
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- vibrating screen exciters fitted with the VE240 tolerance execution
Known failure patterns
- sleeve creep on the shaft seat when the sleeve was not driven to its marked travel or clearance
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- misalignment edge loading when the housing bore is out of square with the shaft seat
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- misalignment edge loading when the housing bore is out of square with the shaft seat
Selection pitfalls — read before you substitute
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C30-560-KM-AOHX30-560 unit — replace the sleeve with the bearing.
- Keep the pair complete in stores: storing bearing C 30/560 KM and sleeve AOHX 30/560 on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- Keep the pair complete in stores: storing bearing C 30/560 KM and sleeve AOHX 30/560 on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- The 5600/11000 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 30/560 KM + AOHX 30/560 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 C30-560-KM-AOHX30-560?
The unit is CARB bearing C 30/560 KM on withdrawal sleeve AOHX 30/560, fitting a 530 mm shaft (20.866 in), housing bore 820 mm, bearing width 195 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 5600 kN, C0 11000 kN, fatigue load limit Pu 720 kN, combined mass about 415.0 kg. Reference speed 530 r/min, limiting speed 750 r/min (bearing values).
Why does C30-560-KM-AOHX30-560 list a 530 mm shaft size when the bearing bore is 560 mm?
The sleeve takes up the difference: the withdrawal sleeve AOHX 30/560 has a tapered outside that engages the bearing's 560 mm tapered bore and a cylindrical bore that seats on the 530 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C30-560-KM-AOHX30-560 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 30/560 KM and the sleeve AOHX 30/560 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 C30-560-KM-AOHX30-560 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C30-560-KM-AOHX30-560 set at mounting?
By sleeve travel: the withdrawal sleeve AOHX 30/560 is driven or pressed to a marked travel on the 530 mm seat, which sets the interference into the 560 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
