How the C3060-KM-OH3060-H model number is decoded
The unit's temp range follows the bearing: -40 to +120 °C continuous for the standard execution; cage and sleeve execution letters on C 3060 KM and OH 3060 H must be checked against the application temperature before substitution.The C3060-KM-OH3060-H unit pairs the 300 mm-bore CARB toroidal roller bearing C 3060 KM with withdrawal sleeve OH 3060 H, so it mounts on a plain cylindrical 280 mm shaft without a precision shoulder.Digit by digit, C3060-KM-OH3060-H = CARB bearing C 3060 KM (300 mm bore, 460 mm OD, 118 mm width) + withdrawal sleeve OH 3060 H for the 280 mm cylindrical shaft seat; cage and tolerance letters stay with the bearing half of the designation. Sleeve discipline: OH 3060 H and bearing C 3060 KM are ground as a matched taper pair — the sleeve's seat diameter and the bearing's bore taper are manufactured together, which is why the catalogue lists the combination as one order number (C3060-KM-OH3060-H). Dividing C 2160 kN by the 300 mm bore gives 7.20 kN per millimetre of journal — compare this density against neighbouring CARB sizes when the 280 mm seat is fixed and the life requirement is not. The locknut torque of OH 3060 H sets the sleeve travel; use the SKF procedure (measure clearance reduction, not torque feel) — over-driving the sleeve preloads the 300 mm CARB bearing and overheats the unit within hours.
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
- sleeve creep on the shaft seat when the sleeve was not driven to its marked travel or clearance
- 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
Selection pitfalls — read before you substitute
- Keep the pair complete in stores: storing bearing C 3060 KM and sleeve OH 3060 H on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C3060-KM-OH3060-H and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- Protect the 280 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 C3060-KM-OH3060-H.
- The 2160/3750 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 3060 KM + OH 3060 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 C3060-KM-OH3060-H?
The unit is CARB bearing C 3060 KM on withdrawal sleeve OH 3060 H, fitting a 280 mm shaft (11.024 in), housing bore 460 mm, bearing width 118 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 2160 kN, C0 3750 kN, fatigue load limit Pu 290 kN, combined mass about 91.0 kg. Reference speed 1,100 r/min, limiting speed 1,500 r/min (bearing values).
Why does C3060-KM-OH3060-H list a 280 mm shaft size when the bearing bore is 300 mm?
The sleeve takes up the difference: the withdrawal sleeve OH 3060 H has a tapered outside that engages the bearing's 300 mm tapered bore and a cylindrical bore that seats on the 280 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C3060-KM-OH3060-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 3060 KM and the sleeve OH 3060 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 C3060-KM-OH3060-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 C3060-KM-OH3060-H set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 280 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.
