How the C2208-V model number is decoded
SKF lists C 2208 V in the dimension series 22 CARB toroidal roller bearings: the toroidal roller profile both follows tolerates angular misalignment and lets the inner ring slide axially inside the outer ring, giving free axial displacement at the non-locating position. The designation C 2208 V separates into C (CARB), 22 (dimension series), 08 (40 mm bore) and V (cylindrical bore for direct shaft fitting, full-complement V execution (no cage)); envelope 40×80×23 mm follows the ISO 15 plan. The cylindrical 40 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 40×80×23 mm are identical — only the mounting method changes. Pairing rule: use the CARB bearing opposite one locating spherical or tapered bearing — never at both shaft ends — and check the locating bearing takes 100 % of the thrust, since C 2208 V deliberately carries none. After fitting, confirm the inner ring can be pushed axially by hand through the catalogue displacement range; a ring that will not slide means the position is locked and will preload in service.
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
- thermal preloading when a shaft is located at both ends and growth has nowhere to go
- brass cage pocket wear under marginal lubrication in the large-bore M/MB executions
- hard-particle indentation where oil or grease filtration is inadequate
- grease churning and overheating when a high-speed thrust position is over-packed
Selection pitfalls — read before you substitute
- At 40 mm bore the small CARB executions are unusually wide (23 mm) for their 80 mm OD — confirm the housing width before substituting a standard spherical bearing of the same bore.
- 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.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 2208 V must float; the two are designed to be used as a pair.
- Never use C 2208 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 40 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
- The 102/104 kN ratings and 530 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 C 2208 V mounted?
Slide or heat (max 120 °C) the bearing onto the 40 mm seat, give the outer ring a loose housing fit, leave the float travel unobstructed, and never press through the 23 mm roller set.
What are the dimensions and ratings of the C 2208 V?
A C 2208 V measures 40 mm bore × 80 mm outside diameter × 23 mm width (1.575 × 3.15 × 0.906 in). From SKF catalogue PUB BU/P1 17000: dynamic C 102 kN, static C0 104 kN, fatigue limit Pu 12.2 kN, limiting speed 4,500 r/min, no reference speed listed, mass about 530 g.
Can a CARB bearing like C 2208 V locate the shaft axially?
No — that is the defining feature. C 2208 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.
How is the C 2208 V designation read?
C = CARB toroidal family; 22 = dimension series; 08 = 40 mm bore (code 08 × 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.
