How the C3036-K-H3036 model number is decoded
The code breaks into bearing C 3036 K and adapter sleeve H 3036: C marks the CARB type, the digit group the 180 mm bore size, the following letters the cage/tolerance execution, and the sleeve designation its own SKF number — sleeve and bearing are keyed to each other and must be ordered as the pair C3036-K-H3036. OH execution note: H 3036 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 160 mm shaft seat during overhauls. With a combined mass of 23.0 kg over the 160×280×74 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. The locknut torque of H 3036 sets the sleeve travel; use the SKF procedure (measure clearance reduction, not torque feel) — over-driving the sleeve preloads the 180 mm CARB bearing and overheats the unit within hours. Spare-parts note: order C3036-K-H3036 as the unit; a bare C 3036 K plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.C3036-K-H3036 is a complete SKF mounting unit: the CARB toroidal roller bearing C 3036 K supplied on its adapter sleeve H 3036, listed in SKF catalogue PUB BU/P1 17000 for a 160 mm shaft seat.
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
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
Known failure patterns
- sleeve creep on the shaft seat when the sleeve was not driven to its marked travel or clearance
- 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
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
Selection pitfalls — read before you substitute
- Protect the 160 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 C3036-K-H3036.
- Sleeve and bearing are a matched taper pair: never fit sleeve H 3036 onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- Contamination discipline: the CARB bearing is open (this execution has no seals); flush the housing before mounting C3036-K-H3036 and maintain the lubricant filtration — hard particles indent the toroidal raceway quickly at heavy load.
- The 880/1340 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 3036 K + H 3036 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 C3036-K-H3036?
The unit is CARB bearing C 3036 K on adapter sleeve H 3036, fitting a 160 mm shaft (6.299 in), housing bore 280 mm, bearing width 74 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 880 kN, C0 1340 kN, fatigue load limit Pu 122 kN, combined mass about 23.0 kg. Reference speed 2,000 r/min, limiting speed 2,600 r/min (bearing values).
Why does C3036-K-H3036 list a 160 mm shaft size when the bearing bore is 180 mm?
The sleeve takes up the difference: the adapter sleeve H 3036 has a tapered outside that engages the bearing's 180 mm tapered bore and a cylindrical bore that seats on the 160 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C3036-K-H3036 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 3036 K and the sleeve H 3036 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 C3036-K-H3036 as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C3036-K-H3036 set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 160 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.
