How the C3224-K-H2324-L model number is decoded
SKF C 3224 K + H 2324 L is the SKF catalogue designation for a CARB toroidal roller bearing delivered on a sleeve: bearing C 3224 K, adapter sleeve H 2324 L, fitting a 110 mm cylindrical shaft seat at 215 mm housing diameter.On the SKF nameplate, C3224-K-H2324-L reads as two catalogued components: the CARB bearing C 3224 K with its 120 mm tapered (K) bore, and the adapter sleeve H 2324 L whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 110 mm shaft size. The H 2324 L execution mounts the 120 mm K-bore bearing with a controlled squeeze on the 110 mm shaft: the sleeve cone sets both the interference fit on the shaft and the running clearance inside the CARB bearing, so clearance measurement belongs to the mounting procedure, not to fitting feel. Selection arithmetic: the unit carries the ratings of its bearing — C 750 kN, C0 980 kN, Pu 98 kN from the CARB table — because the sleeve adds no capacity, only the mounting interface on the 110 mm shaft. Dismounting: release the locknut of H 2324 L, drive the sleeve back off its cone — never hammer the inner ring; the CARB bearing separates from the shaft with the sleeve and stays serviceable if the raceways are sound. Spare-parts note: order C3224-K-H2324-L as the unit; a bare C 3224 K plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.
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
- 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
- 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
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
Selection pitfalls — read before you substitute
- Do not run C3224-K-H2324-L 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.
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C3224-K-H2324-L and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.

- The 750/980 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 3224 K + H 2324 L 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 C3224-K-H2324-L?
The unit is CARB bearing C 3224 K on adapter sleeve H 2324 L, fitting a 110 mm shaft (4.331 in), housing bore 215 mm, bearing width 76 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 750 kN, C0 980 kN, fatigue load limit Pu 98 kN, combined mass about 14.0 kg. Reference speed 2,400 r/min, limiting speed 3,200 r/min (bearing values).
Why does C3224-K-H2324-L list a 110 mm shaft size when the bearing bore is 120 mm?
The sleeve takes up the difference: the adapter sleeve H 2324 L has a tapered outside that engages the bearing's 120 mm tapered bore and a cylindrical bore that seats on the 110 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C3224-K-H2324-L 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 3224 K and the sleeve H 2324 L 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 C3224-K-H2324-L as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C3224-K-H2324-L set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 110 mm shaft and onto the bearing bore, reducing the radial internal clearance. Mount in steps and measure residual clearance until it reaches the catalogue value for the K bore — never set it by nut torque alone.
