How the C2206-V model number is decoded
C 2206 V is a CARB toroidal roller bearing to ISO 15: a single row of long, symmetrical barrel-shaped rollers between guide flanges, sized 30×62×20 mm, as listed in SKF catalogue PUB BU/P1 17000 ch. 10.1. In C 2206 V the 22 dimension series fixes the 62 mm OD and 20 mm width around the 30 mm bore (code 06 × 5); the suffix V then selects the cylindrical bore for direct shaft fitting, full-complement V execution (no cage). CARB bearings locate neither radially nor axially: the inner ring can walk axially inside the outer ring over the catalogue-listed axial-displacement range (s), so shaft thermal growth disappears as thrust rather than preloading the 30 mm seat. No thermal reference speed is listed for this full-complement execution; the mechanical limiting speed is 6,000 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. Mounting: slide the bearing onto the 30 mm seat or heat it (max 120 °C) and seat it square; never press through the 20 mm roller set, and leave the free-end housing shoulder clear so axial float is unrestricted.
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
- 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
- false brinelling and rust-red witness marks on standby machines under external vibration
- grease churning and overheating when a high-speed thrust position is over-packed
Selection pitfalls — read before you substitute
- At 30 mm bore the small CARB executions are unusually wide (20 mm) for their 62 mm OD — confirm the housing width before substituting a standard spherical bearing of the same bore.
- Never use C 2206 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 30 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
- The quoted 76.5/71 kN ratings belong to this exact execution (C 2206 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.
- The 76.5/71 kN ratings and 290 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
What is the difference between V and TN9 CARB executions?
V is the full-complement execution with no cage — more rollers, higher C (76.5 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 2206 V is the cylindrical bore for direct shaft fitting, full-complement V execution (no cage).
How is C 2206 V mounted?
Slide or heat (max 120 °C) the bearing onto the 30 mm seat, give the outer ring a loose housing fit, leave the float travel unobstructed, and never press through the 20 mm roller set.
What are the dimensions and ratings of the C 2206 V?
A C 2206 V measures 30 mm bore × 62 mm outside diameter × 20 mm width (1.181 × 2.441 × 0.787 in). From SKF catalogue PUB BU/P1 17000: dynamic C 76.5 kN, static C0 71 kN, fatigue limit Pu 8.3 kN, limiting speed 6,000 r/min, no reference speed listed, mass about 290 g.
Can a CARB bearing like C 2206 V locate the shaft axially?
No — that is the defining feature. C 2206 V deliberately allows the inner ring to float axially inside the outer ring while the toroidal rollers self-align. It must be paired with a separate locating bearing (spherical, tapered or angular contact) that takes 100 % of the thrust.
