How the C3096-KM-AOHX3096-G model number is decoded
On the SKF nameplate, C3096-KM-AOHX3096-G reads as two catalogued components: the CARB bearing C 3096 KM with its 480 mm tapered (K) bore, and the withdrawal sleeve AOHX 3096 G whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 460 mm shaft size. Sleeve discipline for AOHX 3096 G: 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. With a combined mass of 245.0 kg over the 460×700×165 mm principal plan, the unit replaces a machined shoulder seat — the mass difference against the bare bearing is the sleeve steel, priced into the one order number. Mounting C3096-KM-AOHX3096-G at this size: warm the bearing, drive the withdrawal sleeve to its marked travel on the 460 mm seat and verify the residual radial clearance of the 480 mm CARB bearing before the unit cools — the marked travel is the setting record for the next overhaul. The unit's temp range follows the bearing: -40 to +120 °C continuous for the standard execution; cage and sleeve execution letters on C 3096 KM and AOHX 3096 G must be checked against the application temperature before substitution.SKF C 3096 KM + AOHX 3096 G denotes bearing C 3096 KM mounted on withdrawal sleeve AOHX 3096 G: a 460 mm shaft seat, 700 mm housing bore, and the sleeve providing the interference a 480 mm tapered bore needs.
Typical equipment & failure modes
Common applications
- heavy industrial gearbox layshafts used as the non-locating position
- winder and reel drums in paper and steel strip plants
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
Known failure patterns
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
- 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
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
- misalignment edge loading when the housing bore is out of square with the shaft seat
Selection pitfalls — read before you substitute
- Do not run C3096-KM-AOHX3096-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 4050/7800 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 3096 KM + AOHX 3096 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 C3096-KM-AOHX3096-G?
The unit is CARB bearing C 3096 KM on withdrawal sleeve AOHX 3096 G, fitting a 460 mm shaft (18.11 in), housing bore 700 mm, bearing width 165 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 4050 kN, C0 7800 kN, fatigue load limit Pu 530 kN, combined mass about 245.0 kg. Reference speed 670 r/min, limiting speed 900 r/min (bearing values).
Why does C3096-KM-AOHX3096-G list a 460 mm shaft size when the bearing bore is 480 mm?
The sleeve takes up the difference: the withdrawal sleeve AOHX 3096 G has a tapered outside that engages the bearing's 480 mm tapered bore and a cylindrical bore that seats on the 460 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C3096-KM-AOHX3096-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 3096 KM and the sleeve AOHX 3096 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 C3096-KM-AOHX3096-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 C3096-KM-AOHX3096-G set at mounting?
By sleeve travel: the withdrawal sleeve AOHX 3096 G is driven or pressed to a marked travel on the 460 mm seat, which sets the interference into the 480 mm bore and with it the radial clearance. Record the travel; hydraulic assistance is standard at this size.
