How the C2222 model number is decoded
The CARB bearing C 2222 combines the self-aligning behaviour of a spherical roller bearing with the axial freedom of a cylindrical bearing in one 110 mm bore, 200 mm outside diameter, 53 mm wide unit rated 530 kN dynamic. In C 2222 the 22 dimension series fixes the 200 mm OD and 53 mm width around the 110 mm bore (code 22 × 5); the suffix the bare number then selects the cylindrical bore for direct shaft fitting, pressed steel 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 110 mm seat. Selection arithmetic: C 530 kN against C0 620 kN gives a C0/C ratio of 1.17, and the 64 kN fatigue load limit Pu sets the contamination-adjusted life floor. Seat tolerances follow the ISO 15 recommendation for the normal-load position — the 200 mm outer ring typically takes a loose housing fit to preserve float, and the rings must be supported across their full faces.
Typical equipment & failure modes
Common applications
- vibrating screen exciters fitted with the VE240 tolerance execution
- 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
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
- rolling-contact fatigue spalling after the catalogue L10 life is exhausted
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
Selection pitfalls — read before you substitute
- At 110 mm bore, shaft expansion is already measurable: calculate the required float inside the 53 mm wide bearing rather than assuming the free-end clearance is "enough" at operating temperature.
- Reference and limiting speeds are different limits: the 3,200 r/min reference speed is the thermal criterion under load, the limiting value is the mechanical ceiling; observe the reference under load unless the arrangement calculation says otherwise.
- The quoted 530/620 kN ratings belong to this exact execution (C 2222); 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 2222 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 530/620 kN ratings and 7000 g mass are SKF catalogue values transcribed from ch. 10.1 of PUB BU/P1 17000 (PDF table page 860); 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 (530 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 2222 is the cylindrical bore for direct shaft fitting, pressed steel cage.
How is C 2222 mounted?
Slide or heat (max 120 °C) the bearing onto the 110 mm seat, give the outer ring a loose housing fit, leave the float travel unobstructed, and never press through the 53 mm roller set.
What are the dimensions and ratings of the C 2222?
A C 2222 measures 110 mm bore × 200 mm outside diameter × 53 mm width (4.331 × 7.874 × 2.087 in). From SKF catalogue PUB BU/P1 17000: dynamic C 530 kN, static C0 620 kN, fatigue limit Pu 64 kN, reference speed 3,200 r/min, limiting speed 4,300 r/min, mass about 7000 g.
Can a CARB bearing like C 2222 locate the shaft axially?
No — that is the defining feature. C 2222 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.
