How the C2222-K-AHX3122 model number is decoded
In SKF catalogue PUB BU/P1 17000, C2222-K-AHX3122 appears as bearing C 2222 K + withdrawal sleeve AHX 3122 — the large-size execution of the CARB non-locating principle, delivered as one assembly weighing 8 kg.Reading the designation: C 2222 K is the CARB toroidal roller bearing itself — self-aligning, designed as the non-locating bearing that lets the shaft float axially — and the withdrawal sleeve AHX 3122 carries the tapered bore seat on a 105 mm cylindrical shaft. The suffix letters on the bearing fix cage and tolerance execution; the sleeve number is keyed to the bearing bore. Sleeve discipline for AHX 3122: 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. Dividing C 530 kN by the 110 mm bore gives 4.82 kN per millimetre of journal — compare this density against neighbouring CARB sizes when the 105 mm seat is fixed and the life requirement is not. Mounting C2222-K-AHX3122 at this size: warm the bearing, drive the withdrawal sleeve to its marked travel on the 105 mm seat and verify the residual radial clearance of the 110 mm CARB bearing before the unit cools — the marked travel is the setting record for the next overhaul. Spare-parts note: order C2222-K-AHX3122 as the unit; a bare C 2222 K 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
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- sleeve creep on the shaft seat when the sleeve was not driven to its marked travel or clearance
- 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
Selection pitfalls — read before you substitute
- Do not run C2222-K-AHX3122 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.
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C2222-K-AHX3122 and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- Protect the 105 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 C2222-K-AHX3122.
- The 530/620 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 2222 K + AHX 3122 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 C2222-K-AHX3122?
The unit is CARB bearing C 2222 K on withdrawal sleeve AHX 3122, fitting a 105 mm shaft (4.134 in), housing bore 200 mm, bearing width 53 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 530 kN, C0 620 kN, fatigue load limit Pu 64 kN, combined mass about 7.7 kg. Reference speed 3,200 r/min, limiting speed 4,300 r/min (bearing values).
Why does C2222-K-AHX3122 list a 105 mm shaft size when the bearing bore is 110 mm?
The sleeve takes up the difference: the withdrawal sleeve AHX 3122 has a tapered outside that engages the bearing's 110 mm tapered bore and a cylindrical bore that seats on the 105 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2222-K-AHX3122 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 2222 K and the sleeve AHX 3122 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 C2222-K-AHX3122 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2222-K-AHX3122 set at mounting?
By sleeve travel: the withdrawal sleeve AHX 3122 is driven or pressed to a marked travel on the 105 mm seat, which sets the interference into the 110 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
