How the C2216-K-H316-E 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 2216 K and H 316 E must be checked against the application temperature before substitution.The C2216-K-H316-E unit pairs the 80 mm-bore CARB toroidal roller bearing C 2216 K with adapter sleeve H 316 E, so it mounts on a plain cylindrical 70 mm shaft without a precision shoulder.On the SKF nameplate, C2216-K-H316-E reads as two catalogued components: the CARB bearing C 2216 K with its 80 mm tapered (K) bore, and the adapter sleeve H 316 E whose seat diameter matches that bore — the sleeve number encodes the bearing bore, never the 70 mm shaft size. OH execution note: H 316 E 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 70 mm shaft seat during overhauls. With a combined mass of 2.9 kg over the 70×140×33 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. Dismounting: release the locknut of H 316 E, 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.
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
- 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
- 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
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
Selection pitfalls — read before you substitute
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C2216-K-H316-E unit — replace the sleeve with the bearing.
- Do not re-use a sleeve that shows taper scuffing: a scratched cone changes the travel-to-clearance relationship of the whole C2216-K-H316-E unit — replace the sleeve with the bearing.
- Sleeve and bearing are a matched taper pair: never fit sleeve H 316 E onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- The 220/250 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 2216 K + H 316 E 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 C2216-K-H316-E?
The unit is CARB bearing C 2216 K on adapter sleeve H 316 E, fitting a 70 mm shaft (2.756 in), housing bore 140 mm, bearing width 33 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 220 kN, C0 250 kN, fatigue load limit Pu 28.5 kN, combined mass about 2.9 kg. Reference speed 4,300 r/min, limiting speed 6,000 r/min (bearing values).
Why does C2216-K-H316-E list a 70 mm shaft size when the bearing bore is 80 mm?
The sleeve takes up the difference: the adapter sleeve H 316 E has a tapered outside that engages the bearing's 80 mm tapered bore and a cylindrical bore that seats on the 70 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2216-K-H316-E 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 2216 K and the sleeve H 316 E 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 C2216-K-H316-E as one catalogue line keeps bearing and sleeve compatible; if ordering separately, quote both full designations including execution letters.
How is the clearance of C2216-K-H316-E set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 70 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.
