How the C2209-V model number is decoded
For long shafts that grow thermally, SKF supplies C 2209 V: the toroidal rollers allow the 45 mm inner ring to displace axially without induced thrust, while still accommodating shaft deflection like a spherical bearing. In C 2209 V the 22 dimension series fixes the 85 mm OD and 23 mm width around the 45 mm bore (code 09 × 5); the suffix V then selects the cylindrical bore for direct shaft fitting, full-complement V execution (no cage). The V suffix denotes a full complement: the toroidal rollers fill the 23 mm space without a cage, raising C to 106 kN but cutting the speed ceiling (no reference speed is listed) versus the caged size. 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 2209 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
- long fan and kiln main shafts where the free end must float without thrust load
- heavy industrial gearbox layshafts used as the non-locating position
- winder and reel drums in paper and steel strip plants
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
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
- PA66 cage (TN9) softening when the sustained temperature passes the polymer limit
- 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 45 mm bore the small CARB executions are unusually wide (23 mm) for their 85 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 106/110 kN ratings belong to this exact execution (C 2209 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.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 2209 V must float; the two are designed to be used as a pair.
- The 106/110 kN ratings and 580 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 2209 V mounted?
Slide or heat (max 120 °C) the bearing onto the 45 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 2209 V?
A C 2209 V measures 45 mm bore × 85 mm outside diameter × 23 mm width (1.772 × 3.346 × 0.906 in). From SKF catalogue PUB BU/P1 17000: dynamic C 106 kN, static C0 110 kN, fatigue limit Pu 12.9 kN, limiting speed 4,300 r/min, no reference speed listed, mass about 580 g.
Can a CARB bearing like C 2209 V locate the shaft axially?
No — that is the defining feature. C 2209 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 2209 V designation read?
C = CARB toroidal family; 22 = dimension series; 09 = 45 mm bore (code 09 × 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.
