How the C2220-K-H320-E model number is decoded
In SKF catalogue PUB BU/P1 17000, C2220-K-H320-E appears as bearing C 2220 K + adapter sleeve H 320 E: the non-locating CARB principle combined with a tapered-bore sleeve seat for a 90 mm shaft.The code breaks into bearing C 2220 K and adapter sleeve H 320 E: C marks the CARB type, the digit group the 100 mm bore size, the following letters the cage/tolerance execution, and the sleeve designation its own SKF number — sleeve and bearing are keyed to each other and must be ordered as the pair C2220-K-H320-E. OH execution note: H 320 E is a withdrawal-type sleeve — it gives a more defined interference than a locknut adapter and can be removed without heavy hammer work, which at this bearing size protects the 90 mm shaft seat during overhauls. The C0/C balance of about 1.12 shows the non-locating CARB character: heavy radial capacity with tolerance of misalignment and axial float — the adapter sleeve adds the plain-shaft mounting ability, not thrust capability. The locknut torque of H 320 E sets the sleeve travel; use the SKF procedure (measure clearance reduction, not torque feel) — over-driving the sleeve preloads the 100 mm CARB bearing and overheats the unit within hours. The unit's temp range follows the bearing: -40 to +120 °C continuous for the standard execution; cage and sleeve execution letters on C 2220 K and H 320 E must be checked against the application temperature before substitution.
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
- continuous-caster guide rolls and slab-caster segments under heat growth
Known failure patterns
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- 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
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
Selection pitfalls — read before you substitute
- Sleeve and bearing are a matched taper pair: never fit sleeve H 320 E onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C2220-K-H320-E unit — replace the sleeve with the bearing.
- Keep the pair complete in stores: storing bearing C 2220 K and sleeve H 320 E on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- The 415/465 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 2220 K + H 320 E 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 C2220-K-H320-E?
The unit is CARB bearing C 2220 K on adapter sleeve H 320 E, fitting a 90 mm shaft (3.543 in), housing bore 180 mm, bearing width 46 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 415 kN, C0 465 kN, fatigue load limit Pu 49 kN, combined mass about 6.3 kg. Reference speed 3,600 r/min, limiting speed 4,800 r/min (bearing values).
Why does C2220-K-H320-E list a 90 mm shaft size when the bearing bore is 100 mm?
The sleeve takes up the difference: the adapter sleeve H 320 E has a tapered outside that engages the bearing's 100 mm tapered bore and a cylindrical bore that seats on the 90 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2220-K-H320-E 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 2220 K and the sleeve H 320 E 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 C2220-K-H320-E as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2220-K-H320-E set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 90 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.
