How the C39-1060-KMB-OH39-1060-HE model number is decoded
Dividing C 11000 kN by the 1060 mm bore gives 10.38 kN per millimetre of journal — compare this density against neighbouring CARB sizes when the 1000 mm seat is fixed and the life requirement is not. The locknut torque of OH 39/1060 HE sets the sleeve travel; use the SKF procedure (measure clearance reduction, not torque feel) — over-driving the sleeve preloads the 1060 mm CARB bearing and overheats the unit within hours. The unit's temp range follows the bearing: -40 to +120 °C continuous for the standard execution; cage and sleeve execution letters on C 39/1060 KMB and OH 39/1060 HE must be checked against the application temperature before substitution.The C39-1060-KMB-OH39-1060-HE unit pairs the 1060 mm-bore CARB toroidal roller bearing C 39/1060 KMB with withdrawal sleeve OH 39/1060 HE, so it mounts on a plain cylindrical 1000 mm shaft without a precision shoulder.Digit by digit, C39-1060-KMB-OH39-1060-HE = CARB bearing C 39/1060 KMB (1060 mm bore, 1400 mm OD, 250 mm width) + withdrawal sleeve OH 39/1060 HE for the 1000 mm cylindrical shaft seat; cage and tolerance letters stay with the bearing half of the designation. OH execution note: OH 39/1060 HE 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 1000 mm shaft seat during overhauls.
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
- vibrating screen exciters fitted with the VE240 tolerance execution
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
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
- 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
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C39-1060-KMB-OH39-1060-HE and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- Protect the 1000 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 C39-1060-KMB-OH39-1060-HE.
- Keep the pair complete in stores: storing bearing C 39/1060 KMB and sleeve OH 39/1060 HE on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- The 11000/26000 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 39/1060 KMB + OH 39/1060 HE 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 C39-1060-KMB-OH39-1060-HE?
The unit is CARB bearing C 39/1060 KMB on withdrawal sleeve OH 39/1060 HE, fitting a 1000 mm shaft (39.37 in), housing bore 1400 mm, bearing width 250 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 11000 kN, C0 26000 kN, fatigue load limit Pu 1430 kN, combined mass about 1610.0 kg. Reference speed 260 r/min, limiting speed 360 r/min (bearing values).
Why does C39-1060-KMB-OH39-1060-HE list a 1000 mm shaft size when the bearing bore is 1060 mm?
The sleeve takes up the difference: the withdrawal sleeve OH 39/1060 HE has a tapered outside that engages the bearing's 1060 mm tapered bore and a cylindrical bore that seats on the 1000 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C39-1060-KMB-OH39-1060-HE 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 39/1060 KMB and the sleeve OH 39/1060 HE 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 C39-1060-KMB-OH39-1060-HE as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C39-1060-KMB-OH39-1060-HE set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 1000 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.
