How the C2214-KTN9-AH314-G model number is decoded
On the SKF nameplate, C2214-KTN9-AH314-G reads as two catalogued components: the CARB bearing C 2214 KTN9 with its 70 mm tapered (K) bore, and the withdrawal sleeve AH 314 G whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 65 mm shaft size. Withdrawal sleeve AH 314 G: at this size the sleeve is pulled onto the 65 mm seat (hydraulic assistance is standard) and its taper sets the interference into the 70 mm bearing bore — dismounting uses the sleeve's withdrawal thread, protecting shaft and bearing raceways. The C0/C balance of about 1.05 shows the non-locating CARB character: heavy radial capacity with tolerance of misalignment and axial float — the withdrawal sleeve adds the plain-shaft mounting ability, not thrust capability. Mounting C2214-KTN9-AH314-G at this size: warm the bearing, drive the withdrawal sleeve to its marked travel on the 65 mm seat and verify the residual radial clearance of the 70 mm CARB bearing before the unit cools — the marked travel is the setting record for the next overhaul. Housing side of C2214-KTN9-AH314-G is conventional: a 125 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 65 mm shaft.In SKF catalogue PUB BU/P1 17000, C2214-KTN9-AH314-G appears as bearing C 2214 KTN9 + withdrawal sleeve AH 314 G — the large-size execution of the CARB non-locating principle, delivered as one assembly weighing 2 kg.
Typical equipment & failure modes
Common applications
- continuous-caster guide rolls and slab-caster segments under heat growth
- vibrating screen exciters fitted with the VE240 tolerance execution
- long fan and kiln main shafts where the free end must float without thrust load
- long fan and kiln main shafts where the free end must float without thrust load
Known failure patterns
- 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
- 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
- sleeve creep on the shaft seat when the sleeve was not driven to its marked travel or clearance
Selection pitfalls — read before you substitute
- Sleeve and bearing are a matched taper pair: never fit sleeve AH 314 G onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- Protect the 65 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 C2214-KTN9-AH314-G.
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C2214-KTN9-AH314-G unit — replace the sleeve with the bearing.
- The 186/196 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 2214 KTN9 + AH 314 G 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 C2214-KTN9-AH314-G?
The unit is CARB bearing C 2214 KTN9 on withdrawal sleeve AH 314 G, fitting a 65 mm shaft (2.559 in), housing bore 125 mm, bearing width 31 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 186 kN, C0 196 kN, fatigue load limit Pu 22.8 kN, combined mass about 1.7 kg. Reference speed 5,000 r/min, limiting speed 7,000 r/min (bearing values).
Why does C2214-KTN9-AH314-G list a 65 mm shaft size when the bearing bore is 70 mm?
The sleeve takes up the difference: the withdrawal sleeve AH 314 G has a tapered outside that engages the bearing's 70 mm tapered bore and a cylindrical bore that seats on the 65 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2214-KTN9-AH314-G 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 2214 KTN9 and the sleeve AH 314 G 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 C2214-KTN9-AH314-G as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2214-KTN9-AH314-G set at mounting?
By sleeve travel: the withdrawal sleeve AH 314 G is driven or pressed to a marked travel on the 65 mm seat, which sets the interference into the 70 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
