How the C2210-KTN9-AHX310 model number is decoded
Spare-parts note: order C2210-KTN9-AHX310 as the unit; a bare C 2210 KTN9 plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.C2210-KTN9-AHX310 is a complete SKF mounting unit for the largest CARB sizes: the toroidal roller bearing C 2210 KTN9 on withdrawal sleeve AHX 310, listed in SKF catalogue PUB BU/P1 17000 for a 45 mm shaft seat.On the SKF nameplate, C2210-KTN9-AHX310 reads as two catalogued components: the CARB bearing C 2210 KTN9 with its 50 mm tapered (K) bore, and the withdrawal sleeve AHX 310 whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 45 mm shaft size. Combined mass of the unit — bearing C 2210 KTN9 plus sleeve AHX 310 — is about 1 kg; plan lifting gear and heating equipment around the assembly, not the bare bearing. Selection arithmetic: the unit carries the ratings of its bearing — C 98 kN, C0 100 kN, Pu 11.8 kN from the CARB table — because the sleeve adds no capacity, only the mounting interface on the 45 mm shaft. Dismounting uses the withdrawal thread on AHX 310: pull the sleeve back along its cone with the dedicated withdrawal nut or hydraulic tool — the CARB bearing and sleeve come off the 45 mm seat as one piece and the seat stays undamaged.
Typical equipment & failure modes
Common applications
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- continuous-caster guide rolls and slab-caster segments under heat growth
- vibrating screen exciters fitted with the VE240 tolerance execution
- heavy industrial gearbox layshafts used as the non-locating position
Known failure patterns
- 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
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
- 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 C2210-KTN9-AHX310 and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C2210-KTN9-AHX310 and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- Sleeve and bearing are a matched taper pair: never fit sleeve AHX 310 onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- The 98/100 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 2210 KTN9 + AHX 310 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 C2210-KTN9-AHX310?
The unit is CARB bearing C 2210 KTN9 on withdrawal sleeve AHX 310, fitting a 45 mm shaft (1.772 in), housing bore 90 mm, bearing width 23 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 98 kN, C0 100 kN, fatigue load limit Pu 11.8 kN, combined mass about 0.7 kg. Reference speed 7,000 r/min, limiting speed 9,500 r/min (bearing values).
Why does C2210-KTN9-AHX310 list a 45 mm shaft size when the bearing bore is 50 mm?
The sleeve takes up the difference: the withdrawal sleeve AHX 310 has a tapered outside that engages the bearing's 50 mm tapered bore and a cylindrical bore that seats on the 45 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2210-KTN9-AHX310 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 2210 KTN9 and the sleeve AHX 310 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 C2210-KTN9-AHX310 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2210-KTN9-AHX310 set at mounting?
By sleeve travel: the withdrawal sleeve AHX 310 is driven or pressed to a marked travel on the 45 mm seat, which sets the interference into the 50 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
