How the C2222-K-H322-E model number is decoded
Housing side of C2222-K-H322-E is conventional: a 200 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 100 mm shaft.The C2222-K-H322-E unit pairs the 110 mm-bore CARB toroidal roller bearing C 2222 K with adapter sleeve H 322 E, so it mounts on a plain cylindrical 100 mm shaft without a precision shoulder.On the SKF nameplate, C2222-K-H322-E reads as two catalogued components: the CARB bearing C 2222 K with its 110 mm tapered (K) bore, and the adapter sleeve H 322 E whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 100 mm shaft size. The H 322 E execution mounts the 110 mm K-bore bearing with a controlled squeeze on the 100 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. Dividing C 530 kN by the 110 mm bore gives 4.82 kN per millimetre of journal — compare this density against neighbouring CARB sizes when the 100 mm seat is fixed and the life requirement is not. Mounting C2222-K-H322-E: clean the 100 mm seat, slip on sleeve+bearing as one unit, seat against the housing bore 200 mm H7, then drive the adapter sleeve up its cone in small steps, checking radial internal clearance after each step until the catalogue residual clearance for the K bore is reached.
Typical equipment & failure modes
Common applications
- vibrating screen exciters fitted with the VE240 tolerance execution
- long fan and kiln main shafts where the free end must float without thrust load
- heavy industrial gearbox layshafts used as the non-locating position
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
Known failure patterns
- 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
- 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
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
Selection pitfalls — read before you substitute
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C2222-K-H322-E and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- Never set C2222-K-H322-E by locknut torque or "feel": the adapter sleeve travel defines the clearance of the 110 mm CARB bearing — measure residual radial clearance during mounting, in steps.
- Keep the pair complete in stores: storing bearing C 2222 K and sleeve H 322 E on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- The 530/620 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 2222 K + H 322 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 C2222-K-H322-E?
The unit is CARB bearing C 2222 K on adapter sleeve H 322 E, fitting a 100 mm shaft (3.937 in), housing bore 200 mm, bearing width 53 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 530 kN, C0 620 kN, fatigue load limit Pu 64 kN, combined mass about 8.8 kg. Reference speed 3,200 r/min, limiting speed 4,300 r/min (bearing values).
Why does C2222-K-H322-E list a 100 mm shaft size when the bearing bore is 110 mm?
The sleeve takes up the difference: the adapter sleeve H 322 E has a tapered outside that engages the bearing's 110 mm tapered bore and a cylindrical bore that seats on the 100 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2222-K-H322-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 2222 K and the sleeve H 322 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 C2222-K-H322-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 C2222-K-H322-E set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 100 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.
