How the C2234-K-H3134-L model number is decoded
What the H execution changes: an adapter sleeve clamps the 170 mm tapered bore onto a plain 150 mm shaft, so the housing-side location work happens at the sleeve locknut — no machined shaft shoulder is needed at the bearing seat. Dividing C 1270 kN by the 170 mm bore gives 7.47 kN per millimetre of journal — compare this density against neighbouring CARB sizes when the 150 mm seat is fixed and the life requirement is not. Mounting C2234-K-H3134-L: clean the 150 mm seat, slip on sleeve+bearing as one unit, seat against the housing bore 310 mm H7, then drive the adapter 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 C2234-K-H3134-L as the unit; a bare C 2234 K plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.The C2234-K-H3134-L unit pairs the 170 mm-bore CARB toroidal roller bearing C 2234 K with adapter sleeve H 3134 L, so it mounts on a plain cylindrical 150 mm shaft without a precision shoulder.Digit by digit, C2234-K-H3134-L = CARB bearing C 2234 K (170 mm bore, 310 mm OD, 86 mm width) + adapter sleeve H 3134 L for the 150 mm cylindrical shaft seat; cage and tolerance letters stay with the bearing half of the designation.
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
- 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
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
Selection pitfalls — read before you substitute
- Keep the pair complete in stores: storing bearing C 2234 K and sleeve H 3134 L on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- Protect the 150 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 C2234-K-H3134-L.
- Do not run C2234-K-H3134-L 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.
- The 1270/1630 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 2234 K + H 3134 L 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 C2234-K-H3134-L?
The unit is CARB bearing C 2234 K on adapter sleeve H 3134 L, fitting a 150 mm shaft (5.906 in), housing bore 310 mm, bearing width 86 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1270 kN, C0 1630 kN, fatigue load limit Pu 146 kN, combined mass about 35.0 kg. Reference speed 1,900 r/min, limiting speed 2,600 r/min (bearing values).
Why does C2234-K-H3134-L list a 150 mm shaft size when the bearing bore is 170 mm?
The sleeve takes up the difference: the adapter sleeve H 3134 L has a tapered outside that engages the bearing's 170 mm tapered bore and a cylindrical bore that seats on the 150 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2234-K-H3134-L 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 2234 K and the sleeve H 3134 L 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 C2234-K-H3134-L as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2234-K-H3134-L set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 150 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.
