How the C2217-K-H317-E model number is decoded
Reading the designation: C 2217 K is the CARB toroidal roller bearing itself — self-aligning, designed as the non-locating bearing that lets the shaft float axially — and the adapter sleeve H 317 E carries the tapered bore seat on a 75 mm cylindrical shaft. The suffix letters on the bearing fix cage and tolerance execution; the sleeve number is keyed to the bearing bore. The H 317 E execution mounts the 85 mm K-bore bearing with a controlled squeeze on the 75 mm shaft: the sleeve cone sets both the interference fit on the shaft and the running clearance inside the CARB bearing, so clearance measurement belongs to the mounting procedure, not to fitting feel. With a combined mass of 3.7 kg over the 75×150×36 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 317 E sets the sleeve travel; use the SKF procedure (measure clearance reduction, not torque feel) — over-driving the sleeve preloads the 85 mm CARB bearing and overheats the unit within hours. Housing side of C2217-K-H317-E is conventional: a 150 mm H7 bore takes the CARB outer ring, which is free to slide axially in the housing — the toroidal raceway handles the misalignment and the sleeve side handles the location on the 75 mm shaft.SKF C 2217 K + H 317 E is the SKF catalogue designation for a CARB toroidal roller bearing delivered on a sleeve: bearing C 2217 K, adapter sleeve H 317 E, fitting a 75 mm cylindrical shaft seat at 150 mm housing diameter.
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
- 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
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- raceway spalling of the CARB bearing after the catalogue L10 life under contaminated lubrication
Selection pitfalls — read before you substitute
- Sleeve and bearing are a matched taper pair: never fit sleeve H 317 E onto a different CARB bearing of the same bore size without verifying the execution letters — seat length and taper contact differ.
- Keep the pair complete in stores: storing bearing C 2217 K and sleeve H 317 E on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- Never set C2217-K-H317-E by locknut torque or "feel": the adapter sleeve travel defines the clearance of the 85 mm CARB bearing — measure residual radial clearance during mounting, in steps.
- The 275/320 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 2217 K + H 317 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 C2217-K-H317-E?
The unit is CARB bearing C 2217 K on adapter sleeve H 317 E, fitting a 75 mm shaft (2.953 in), housing bore 150 mm, bearing width 36 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 275 kN, C0 320 kN, fatigue load limit Pu 35.5 kN, combined mass about 3.7 kg. Reference speed 4,000 r/min, limiting speed 5,600 r/min (bearing values).
Why does C2217-K-H317-E list a 75 mm shaft size when the bearing bore is 85 mm?
The sleeve takes up the difference: the adapter sleeve H 317 E has a tapered outside that engages the bearing's 85 mm tapered bore and a cylindrical bore that seats on the 75 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2217-K-H317-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 2217 K and the sleeve H 317 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 C2217-K-H317-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 C2217-K-H317-E set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 75 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.
