How the C2319-K-H2319 model number is decoded
Numbering logic: the bearing half C 2319 K follows the CARB works numbering (type C, dimension series, 95 mm bore), while H 2319 identifies the sleeve execution for that bore; the combo C2319-K-H2319 exists in the catalogue so that shaft (85 mm), housing (200 mm) and both components are specified with one order number. What the H execution changes: an adapter sleeve clamps the 95 mm tapered bore onto a plain 85 mm shaft, so the housing-side location work happens at the sleeve locknut — no machined shaft shoulder is needed at the bearing seat. Dividing C 610 kN by the 95 mm bore gives 6.42 kN per millimetre of journal — compare this density against neighbouring CARB sizes when the 85 mm seat is fixed and the life requirement is not. Dismounting: release the locknut of H 2319, 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 C2319-K-H2319 as the unit; a bare C 2319 K plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.The C2319-K-H2319 unit pairs the 95 mm-bore CARB toroidal roller bearing C 2319 K with adapter sleeve H 2319, so it mounts on a plain cylindrical 85 mm shaft without a precision shoulder.
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
- heavy industrial gearbox layshafts used as the non-locating position
Known failure patterns
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized 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 re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C2319-K-H2319 unit — replace the sleeve with the bearing.
- Protect the 85 mm seat: sleeve bore corrosion or seat ovality shows up later as sleeve creep and fretting; inspect and measure the seat at every dismounting of C2319-K-H2319.
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C2319-K-H2319 and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- The 610/695 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 2319 K + H 2319 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 C2319-K-H2319?
The unit is CARB bearing C 2319 K on adapter sleeve H 2319, fitting a 85 mm shaft (3.346 in), housing bore 200 mm, bearing width 67 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 610 kN, C0 695 kN, fatigue load limit Pu 73.5 kN, combined mass about 11.5 kg. Reference speed 2,800 r/min, limiting speed 4,000 r/min (bearing values).
Why does C2319-K-H2319 list a 85 mm shaft size when the bearing bore is 95 mm?
The sleeve takes up the difference: the adapter sleeve H 2319 has a tapered outside that engages the bearing's 95 mm tapered bore and a cylindrical bore that seats on the 85 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2319-K-H2319 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 2319 K and the sleeve H 2319 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 C2319-K-H2319 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2319-K-H2319 set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 85 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.
