How the C3092-KM-OH3092-H model number is decoded
Adapter sleeve OH 3092 H: the sleeve sits between bearing and shaft, its tapered OD engaging the bearing's tapered bore and its cylindrical bore slipping over the 430 mm shaft. Driving the sleeve up its cone expands it on the shaft and sets the bearing's internal clearance at mounting. With a combined mass of 270.0 kg over the 430×680×163 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 C3092-KM-OH3092-H: clean the 430 mm seat, slip on sleeve+bearing as one unit, seat against the housing bore 680 mm H7, then drive the withdrawal 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. Spare-parts note: order C3092-KM-OH3092-H as the unit; a bare C 3092 KM plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.SKF C 3092 KM + OH 3092 H is the SKF catalogue designation for a CARB toroidal roller bearing delivered on a sleeve: bearing C 3092 KM, withdrawal sleeve OH 3092 H, fitting a 430 mm cylindrical shaft seat at 680 mm housing diameter.Digit by digit, C3092-KM-OH3092-H = CARB bearing C 3092 KM (460 mm bore, 680 mm OD, 163 mm width) + withdrawal sleeve OH 3092 H for the 430 mm cylindrical shaft seat; cage and tolerance letters stay with the bearing half of the designation.
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
- vibrating screen exciters fitted with the VE240 tolerance execution
Known failure patterns
- 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
- 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
Selection pitfalls — read before you substitute
- Do not run C3092-KM-OH3092-H 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.
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C3092-KM-OH3092-H unit — replace the sleeve with the bearing.
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C3092-KM-OH3092-H unit — replace the sleeve with the bearing.
- The 4000/7500 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 3092 KM + OH 3092 H 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 C3092-KM-OH3092-H?
The unit is CARB bearing C 3092 KM on withdrawal sleeve OH 3092 H, fitting a 430 mm shaft (16.929 in), housing bore 680 mm, bearing width 163 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 4000 kN, C0 7500 kN, fatigue load limit Pu 520 kN, combined mass about 270.0 kg. Reference speed 700 r/min, limiting speed 950 r/min (bearing values).
Why does C3092-KM-OH3092-H list a 430 mm shaft size when the bearing bore is 460 mm?
The sleeve takes up the difference: the withdrawal sleeve OH 3092 H has a tapered outside that engages the bearing's 460 mm tapered bore and a cylindrical bore that seats on the 430 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C3092-KM-OH3092-H 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 3092 KM and the sleeve OH 3092 H 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 C3092-KM-OH3092-H as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C3092-KM-OH3092-H set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 430 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.
