How the C2220-K-AHX320 model number is decoded
Digit by digit, C2220-K-AHX320 = CARB bearing C 2220 K (100 mm bore, 180 mm OD, 46 mm width) + withdrawal sleeve AHX 320 for the 95 mm cylindrical shaft seat; cage and tolerance letters stay with the bearing half of the designation. Sleeve discipline for AHX 320: 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. Fatigue floor: Pu 49 kN governs the adjusted-life calculation at contaminated or partial-film conditions, exactly as for the bare C 2220 K bearing — the sleeve execution does not change the L10 arithmetic. Mounting C2220-K-AHX320 at this size: warm the bearing, drive the withdrawal sleeve to its marked travel on the 95 mm seat and verify the residual radial clearance of the 100 mm CARB bearing before the unit cools — the marked travel is the setting record for the next overhaul. Spare-parts note: order C2220-K-AHX320 as the unit; a bare C 2220 K plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.C2220-K-AHX320 is a complete SKF mounting unit for the largest CARB sizes: the toroidal roller bearing C 2220 K on withdrawal sleeve AHX 320, listed in SKF catalogue PUB BU/P1 17000 for a 95 mm shaft seat.
Typical equipment & failure modes
Common applications
- winder and reel drums in paper and steel strip plants
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- continuous-caster guide rolls and slab-caster segments under heat growth
- continuous-caster guide rolls and slab-caster segments under heat growth
Known failure patterns
- 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
- 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
- misalignment edge loading when the housing bore is out of square with the shaft seat
Selection pitfalls — read before you substitute
- Do not run C2220-K-AHX320 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.
- Keep the pair complete in stores: storing bearing C 2220 K and sleeve AHX 320 on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- Protect the 95 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 C2220-K-AHX320.
- The 415/465 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 2220 K + AHX 320 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 C2220-K-AHX320?
The unit is CARB bearing C 2220 K on withdrawal sleeve AHX 320, fitting a 95 mm shaft (3.74 in), housing bore 180 mm, bearing width 46 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 415 kN, C0 465 kN, fatigue load limit Pu 49 kN, combined mass about 5.3 kg. Reference speed 3,600 r/min, limiting speed 4,800 r/min (bearing values).
Why does C2220-K-AHX320 list a 95 mm shaft size when the bearing bore is 100 mm?
The sleeve takes up the difference: the withdrawal sleeve AHX 320 has a tapered outside that engages the bearing's 100 mm tapered bore and a cylindrical bore that seats on the 95 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2220-K-AHX320 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 2220 K and the sleeve AHX 320 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 C2220-K-AHX320 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2220-K-AHX320 set at mounting?
By sleeve travel: the withdrawal sleeve AHX 320 is driven or pressed to a marked travel on the 95 mm seat, which sets the interference into the 100 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
