How the C2213-KTN9-AH313-G model number is decoded
Dismounting uses the withdrawal thread on AH 313 G: pull the sleeve back along its cone with the dedicated withdrawal nut or hydraulic tool — the CARB bearing and sleeve come off the 60 mm seat as one piece and the seat stays undamaged. The unit's temp range follows the bearing: -40 to +120 °C continuous for the standard execution; cage and sleeve execution letters on C 2213 KTN9 and AH 313 G must be checked against the application temperature before substitution.The C2213-KTN9-AH313-G unit combines the 65 mm-bore CARB toroidal roller bearing C 2213 KTN9 with withdrawal sleeve AH 313 G, giving controlled mounting interference on a plain 60 mm cylindrical seat.On the SKF nameplate, C2213-KTN9-AH313-G reads as two catalogued components: the CARB bearing C 2213 KTN9 with its 65 mm tapered (K) bore, and the withdrawal sleeve AH 313 G whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 60 mm shaft size. Why a withdrawal sleeve at 60 mm shaft: adapter-sleeve locknut forces become impractical on the 65 mm bore; the AH 313 G execution lets the fitter generate mounting interference with manageable forces and remove the unit later without damaging the seat. The C0/C balance of about 1.00 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.
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
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
- 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
- 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
Selection pitfalls — read before you substitute
- Do not run C2213-KTN9-AH313-G 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.
- Sleeve and bearing are a matched taper pair: never fit sleeve AH 313 G onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- Do not run C2213-KTN9-AH313-G 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.
- The 180/180 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 2213 KTN9 + AH 313 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 C2213-KTN9-AH313-G?
The unit is CARB bearing C 2213 KTN9 on withdrawal sleeve AH 313 G, fitting a 60 mm shaft (2.362 in), housing bore 120 mm, bearing width 31 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 180 kN, C0 180 kN, fatigue load limit Pu 21.2 kN, combined mass about 1.6 kg. Reference speed 5,300 r/min, limiting speed 7,500 r/min (bearing values).
Why does C2213-KTN9-AH313-G list a 60 mm shaft size when the bearing bore is 65 mm?
The sleeve takes up the difference: the withdrawal sleeve AH 313 G has a tapered outside that engages the bearing's 65 mm tapered bore and a cylindrical bore that seats on the 60 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2213-KTN9-AH313-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 2213 KTN9 and the sleeve AH 313 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 C2213-KTN9-AH313-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 C2213-KTN9-AH313-G set at mounting?
By sleeve travel: the withdrawal sleeve AH 313 G is driven or pressed to a marked travel on the 60 mm seat, which sets the interference into the 65 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
