How the C2210-KTN9-H310-E model number is decoded
The C2210-KTN9-H310-E unit pairs the 50 mm-bore CARB toroidal roller bearing C 2210 KTN9 with adapter sleeve H 310 E, so it mounts on a plain cylindrical 45 mm shaft without a precision shoulder.Numbering logic: the bearing half C 2210 KTN9 follows the CARB works numbering (type C, dimension series, 50 mm bore), while H 310 E identifies the sleeve execution for that bore; the combo C2210-KTN9-H310-E exists in the catalogue so that shaft (45 mm), housing (90 mm) and both components are specified with one order number. Sleeve discipline: H 310 E and bearing C 2210 KTN9 are ground as a matched taper pair — the sleeve's seat diameter and the bearing's bore taper are manufactured together, which is why the catalogue lists the combination as one order number (C2210-KTN9-H310-E). Fatigue floor: Pu 11.8 kN governs the adjusted-life calculation at contaminated or partial-film conditions, exactly as for the bare C 2210 KTN9 bearing — the sleeve execution does not change the L10 arithmetic. The locknut torque of H 310 E sets the sleeve travel; use the SKF procedure (measure clearance reduction, not torque feel) — over-driving the sleeve preloads the 50 mm CARB bearing and overheats the unit within hours. Housing side of C2210-KTN9-H310-E is conventional: a 90 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 45 mm shaft.
Typical equipment & failure modes
Common applications
- winder and reel drums in paper and steel strip plants
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- continuous-caster guide rolls and slab-caster segments under heat growth
- winder and reel drums in paper and steel strip plants
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
- overheating from a preload set at mounting when sleeve travel overshot the catalogue clearance
- 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
Selection pitfalls — read before you substitute
- Keep the pair complete in stores: storing bearing C 2210 KTN9 and sleeve H 310 E on different shelves is how taper-mismatch accidents start — store the unit as received under one part number.
- Do not run C2210-KTN9-H310-E 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.
- Never set C2210-KTN9-H310-E by locknut torque or "feel": the adapter sleeve travel defines the clearance of the 50 mm CARB bearing — measure residual radial clearance during mounting, in steps.
- The 98/100 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 2210 KTN9 + H 310 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 C2210-KTN9-H310-E?
The unit is CARB bearing C 2210 KTN9 on adapter sleeve H 310 E, fitting a 45 mm shaft (1.772 in), housing bore 90 mm, bearing width 23 mm. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 98 kN, C0 100 kN, fatigue load limit Pu 11.8 kN, combined mass about 0.8 kg. Reference speed 7,000 r/min, limiting speed 9,500 r/min (bearing values).
Why does C2210-KTN9-H310-E list a 45 mm shaft size when the bearing bore is 50 mm?
The sleeve takes up the difference: the adapter sleeve H 310 E has a tapered outside that engages the bearing's 50 mm tapered bore and a cylindrical bore that seats on the 45 mm shaft. The catalogue's principal dimensions describe the mounted result — shaft seat, housing bore and bearing width — not the bearing bore alone.
Is C2210-KTN9-H310-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 2210 KTN9 and the sleeve H 310 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 C2210-KTN9-H310-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 C2210-KTN9-H310-E set at mounting?
By driving the adapter sleeve up its conical seat: the sleeve expands on the 45 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.
