How the C2211-V model number is decoded
C 2211 V is the dimension series 22 CARB toroidal roller bearings member of the CARB range: 55 mm bore, 100 mm OD, 25 mm width, with the asymmetrical-looking toroidal roller set that defines the CARB principle. The designation C 2211 V separates into C (CARB), 22 (dimension series), 11 (55 mm bore) and V (cylindrical bore for direct shaft fitting, full-complement V execution (no cage)); envelope 55×100×25 mm follows the ISO 15 plan. The V suffix denotes a full complement: the toroidal rollers fill the 25 mm space without a cage, raising C to 132 kN but cutting the speed ceiling (no reference speed is listed) versus the caged size. No thermal reference speed is listed for this full-complement execution; the mechanical limiting speed is 3,400 r/min. The full-complement V executions carry more load but list no thermal reference speed; the steel-caged executions run faster and cooler at light load. Open executions accept relubrication — route it through the outer-ring groove on sizes that have one and purge stale grease at service intervals. Grease through the annular groove features where provided; on open executions feed lubricant past the long roller set at assembly, since the 25 mm wide cavity does not fill itself.
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
- vibrating screen exciters fitted with the VE240 tolerance execution
Known failure patterns
- raceway spalling once the catalogue L10 life is exceeded or after sustained overload
- edge loading and premature spalling when the CARB position is blocked from its designed axial float
- PA66 cage (TN9) softening when the sustained temperature passes the polymer limit
- condensation pitting in machines that run intermittently in humid environments
- grease churning and overheating when a high-speed thrust position is over-packed
Selection pitfalls — read before you substitute
- At 55 mm bore the small CARB executions are unusually wide (25 mm) for their 100 mm OD — confirm the housing width before substituting a standard spherical bearing of the same bore.
- Reference and limiting speeds are different limits: the catalogue lists no thermal reference speed for this full-complement/sealed execution, the limiting value is the mechanical ceiling; observe the reference under load unless the arrangement calculation says otherwise.
- The quoted 132/134 kN ratings belong to this exact execution (C 2211 V); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
- Never use C 2211 V as the locating bearing: it carries no axial load by design — the arrangement needs a separate locating spherical, tapered or angular bearing facing the thrust.
- Tapered-bore K executions mount on adapter sleeves (1:12) and K30 on withdrawal sleeves (1:30) — the 55 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
- The 132/134 kN ratings and 820 g mass are SKF catalogue values transcribed from ch. 10.1 of PUB BU/P1 17000 (PDF table page 858); mounting data — axial displacement (s) and seating details — appears in the running text because the structured record carries the boundary envelope only.
Frequently asked questions
How is the C 2211 V designation read?
C = CARB toroidal family; 22 = dimension series; 11 = 55 mm bore (code 11 × 5); suffix V selects cylindrical bore for direct shaft fitting, full-complement V execution (no cage). K is a 1:12 tapered bore for an adapter sleeve, K30 a 1:30 bore for a withdrawal sleeve.
What is the difference between V and TN9 CARB executions?
V is the full-complement execution with no cage — more rollers, higher C (132 kN here) but a lower speed ceiling and no thermal reference speed. TN9 is the glass-fibre PA66 caged execution, faster and quieter at somewhat lower load. C 2211 V is the cylindrical bore for direct shaft fitting, full-complement V execution (no cage).
How is C 2211 V mounted?
Slide or heat (max 120 °C) the bearing onto the 55 mm seat, give the outer ring a loose housing fit, leave the float travel unobstructed, and never press through the 25 mm roller set.
What are the dimensions and ratings of the C 2211 V?
A C 2211 V measures 55 mm bore × 100 mm outside diameter × 25 mm width (2.165 × 3.937 × 0.984 in). From SKF catalogue PUB BU/P1 17000: dynamic C 132 kN, static C0 134 kN, fatigue limit Pu 15.6 kN, limiting speed 3,400 r/min, no reference speed listed, mass about 820 g.
