How the C3096-KM-OH3096-H model number is decoded
The locknut torque of OH 3096 H sets the sleeve travel; use the SKF procedure (measure clearance reduction, not torque feel) — over-driving the sleeve preloads the 480 mm CARB bearing and overheats the unit within hours. Spare-parts note: order C3096-KM-OH3096-H as the unit; a bare C 3096 KM plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.Ordering C3096-KM-OH3096-H buys one matched assembly — CARB bearing C 3096 KM on withdrawal sleeve OH 3096 H — rather than a bearing and a sleeve ordered separately for a 450 mm shaft.On the SKF nameplate, C3096-KM-OH3096-H reads as two catalogued components: the CARB bearing C 3096 KM with its 480 mm tapered (K) bore, and the withdrawal sleeve OH 3096 H whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 450 mm shaft size. OH execution note: OH 3096 H 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 450 mm shaft seat during overhauls. Speed note: for C3096-KM-OH3096-H the CARB table lists 670 r/min reference and 900 r/min limiting speed the permissible speed of the unit is bounded by the CARB bearing's own catalogue values and by the sleeve-seat interface; sleeve-mounted units run marginally cooler-balanced because the sleeve adds a thermal resistance at the 450 mm seat.
Typical equipment & failure modes
Common applications
- 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
- winder and reel drums in paper and steel strip plants
- winder and reel drums in paper and steel strip plants
Known failure patterns
- 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
- 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
- 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 OH 3096 H onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- Sleeve and bearing are a matched taper pair: never fit sleeve OH 3096 H onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- Keep the pair complete in stores: storing bearing C 3096 KM and sleeve OH 3096 H on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- The 4050/7800 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 3096 KM + OH 3096 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 C3096-KM-OH3096-H?
The unit is CARB bearing C 3096 KM on withdrawal sleeve OH 3096 H, fitting a 450 mm shaft (17.717 in), housing bore 700 mm, bearing width 165 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 4050 kN, C0 7800 kN, fatigue load limit Pu 530 kN, combined mass about 275.0 kg. Reference speed 670 r/min, limiting speed 900 r/min (bearing values).
Why does C3096-KM-OH3096-H list a 450 mm shaft size when the bearing bore is 480 mm?
The sleeve takes up the difference: the withdrawal sleeve OH 3096 H has a tapered outside that engages the bearing's 480 mm tapered bore and a cylindrical bore that seats on the 450 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C3096-KM-OH3096-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 3096 KM and the sleeve OH 3096 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 C3096-KM-OH3096-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 C3096-KM-OH3096-H set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 450 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.
