How the C2207-V model number is decoded
C 2207 V belongs to the CARB family — compact aligning roller bearings: envelope 35×72×23 mm, radial rating 95/96 kN C/C0, and no axial-locating function by design. SKF builds the CARB order number from size plus execution: the bare number C 2207 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 35 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 35×72×23 mm are identical — only the mounting method changes. The 460 g mass over the 35×72×23 mm envelope yields about 2.71 kN dynamic per millimetre of bore — the long toroidal rollers give this family its radial capacity density. Mounting: slide the bearing onto the 35 mm seat or heat it (max 120 °C) and seat it square; never press through the 23 mm roller set, and leave the free-end housing shoulder clear so axial float is unrestricted.
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
- 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
- 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 35 mm bore the small CARB executions are unusually wide (23 mm) for their 72 mm OD — confirm the housing width before substituting a standard spherical bearing of the same bore.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 2207 V must float; the two are designed to be used as a pair.
- Never use C 2207 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.
- The quoted 95/96 kN ratings belong to this exact execution (C 2207 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 95/96 kN ratings and 460 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
Is the C 2207 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 2207 V have?
A C 2207 V measures 35 mm bore × 72 mm outside diameter × 23 mm width (1.378 × 2.835 × 0.906 in). From SKF catalogue PUB BU/P1 17000: dynamic C 95 kN, static C0 96 kN, fatigue limit Pu 11.2 kN, limiting speed 5,300 r/min, no reference speed listed, mass about 460 g.
What does C 2207 V mean in SKF part numbering?
C marks CARB; 22 the dimension series; the size code gives 35 mm bore; V is the execution (cylindrical bore for direct shaft fitting, full-complement V execution (no cage)). The envelope follows ISO 15 and matches spherical roller bearing outlines, but the functions differ.
