How the C3132-K-H3132-L model number is decoded
What the H execution changes: an adapter sleeve clamps the 160 mm tapered bore onto a plain 140 mm shaft, so the housing-side location work happens at the sleeve locknut — no machined shaft shoulder is needed at the bearing seat. Selection arithmetic: the unit carries the ratings of its bearing — C 1000 kN, C0 1400 kN, Pu 129 kN from the CARB table — because the sleeve adds no capacity, only the mounting interface on the 140 mm shaft. Dismounting: release the locknut of H 3132 L, drive the sleeve back off its cone — never hammer the inner ring; the CARB bearing separates from the shaft with the sleeve and stays serviceable if the raceways are sound. Spare-parts note: order C3132-K-H3132-L as the unit; a bare C 3132 K plus a separately sourced sleeve risks taper mismatch — the catalogue pairing is the guarantee that seat and bore were ground for each other.In SKF catalogue PUB BU/P1 17000, C3132-K-H3132-L appears as bearing C 3132 K + adapter sleeve H 3132 L: the non-locating CARB principle combined with a tapered-bore sleeve seat for a 140 mm shaft.On the SKF nameplate, C3132-K-H3132-L reads as two catalogued components: the CARB bearing C 3132 K with its 160 mm tapered (K) bore, and the adapter sleeve H 3132 L whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 140 mm shaft size.
Typical equipment & failure modes
Common applications
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- continuous-caster guide rolls and slab-caster segments under heat growth
- vibrating screen exciters fitted with the VE240 tolerance execution
- heavy industrial gearbox layshafts used as the non-locating position
Known failure patterns
- 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
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
- fretting corrosion at the shaft-sleeve interface under vibration with an undersized seat
Selection pitfalls — read before you substitute
- Do not run C3132-K-H3132-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.
- Do not run C3132-K-H3132-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.
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C3132-K-H3132-L unit — replace the sleeve with the bearing.
- The 1000/1400 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 3132 K + H 3132 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 C3132-K-H3132-L?
The unit is CARB bearing C 3132 K on adapter sleeve H 3132 L, fitting a 140 mm shaft (5.512 in), housing bore 270 mm, bearing width 86 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1000 kN, C0 1400 kN, fatigue load limit Pu 129 kN, combined mass about 27.0 kg. Reference speed 1,900 r/min, limiting speed 2,600 r/min (bearing values).
Why does C3132-K-H3132-L list a 140 mm shaft size when the bearing bore is 160 mm?
The sleeve takes up the difference: the adapter sleeve H 3132 L has a tapered outside that engages the bearing's 160 mm tapered bore and a cylindrical bore that seats on the 140 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C3132-K-H3132-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 3132 K and the sleeve H 3132 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 C3132-K-H3132-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 C3132-K-H3132-L set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 140 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.
