How the C2210-V model number is decoded
The CARB bearing C 2210 V combines the self-aligning behaviour of a spherical roller bearing with the axial freedom of a cylindrical bearing in one 50 mm bore, 90 mm outside diameter, 23 mm wide unit rated 114 kN dynamic. SKF builds the CARB order number from size plus execution: the bare number C 2210 is the full-complement cylindrical-bore bearing, K (or K30) makes the bore tapered for sleeve mounting, and the cage/seal letters follow — here V. The cylindrical 50 mm bore mounts directly on a machined seat; the outer ring takes a loose housing fit so the bearing can float axially. The same size is listed in both bore executions, and the boundary dimensions 50×90×23 mm are identical — only the mounting method changes. Selection arithmetic: C 114 kN against C0 122 kN gives a C0/C ratio of 1.07, and the 14.3 kN fatigue load limit Pu sets the contamination-adjusted life floor. 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 23 mm wide cavity does not fill itself.
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
- long fan and kiln main shafts where the free end must float without thrust load
Known failure patterns
- roller-end and flange smearing after lubricant starvation at the long roller contacts
- edge loading and premature spalling when the CARB position is blocked from its designed axial float
- brass cage pocket wear under marginal lubrication in the large-bore M/MB executions
- 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 50 mm bore the small CARB executions are unusually wide (23 mm) for their 90 mm OD — confirm the housing width before substituting a standard spherical bearing of the same bore.
- The quoted 114/122 kN ratings belong to this exact execution (C 2210 V); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
- Do not block the axial displacement in the drawing: housing covers, labyrinth rings and snap rings must leave the catalogue float (s) free, or the bearing silently becomes a poorly located fixed bearing.
- Never use C 2210 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 50 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
- The 114/122 kN ratings and 630 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
Why is C 2210 V used opposite a spherical roller bearing?
The spherical bearing locates the shaft and takes thrust; the CARB bearing at the other end self-aligns but floats, absorbing thermal expansion without inducing axial load. The pair is standard on paper machine drying cylinders and long caster rolls.
Is the C 2210 V sealed?
No, it is an open execution relying on the housing seals; the full-complement V design has no thermal reference speed in the catalogue.
What fails first on a misapplied CARB bearing?
Blocking the designed axial float — clamping the free end or locating both shaft ends — turns thermal growth into edge loading and spalls the toroidal raceways. Cage damage and ordinary fatigue follow overload or dry running.
Which dimensions does the C 2210 V have?
A C 2210 V measures 50 mm bore × 90 mm outside diameter × 23 mm width (1.969 × 3.543 × 0.906 in). From SKF catalogue PUB BU/P1 17000: dynamic C 114 kN, static C0 122 kN, fatigue limit Pu 14.3 kN, limiting speed 3,800 r/min, no reference speed listed, mass about 630 g.
