How the C2216-KV model number is decoded
SKF lists C 2216 KV 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. In C 2216 KV the 22 dimension series fixes the 140 mm OD and 33 mm width around the 80 mm bore (code 16 × 5); the suffix KV then selects the tapered 1:12 bore for adapter (H) sleeve mounting, full-complement V execution (no cage). The V suffix denotes a full complement: the toroidal rollers fill the 33 mm space without a cage, raising C to 255 kN but cutting the speed ceiling (no reference speed is listed) versus the caged size. Selection arithmetic: C 255 kN against C0 305 kN gives a C0/C ratio of 1.20, and the 34.5 kN fatigue load limit Pu sets the contamination-adjusted life floor. Seat tolerances follow the ISO 15 recommendation for the normal-load position — the 140 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
- 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 80 mm bore the small CARB executions are unusually wide (33 mm) for their 140 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 255/305 kN ratings belong to this exact execution (C 2216 KV); 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 2216 KV 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 255/305 kN ratings and 2150 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
How is C 2216 KV mounted?
The tapered 1:12 bore mounts on an adapter (H) sleeve with a defined drive-up; heat the bearing to max 120 °C when fitting, support full ring faces, and verify axial float afterwards.
What are the dimensions and ratings of the C 2216 KV?
A C 2216 KV measures 80 mm bore × 140 mm outside diameter × 33 mm width (3.15 × 5.512 × 1.299 in). From SKF catalogue PUB BU/P1 17000: dynamic C 255 kN, static C0 305 kN, fatigue limit Pu 34.5 kN, limiting speed 2,000 r/min, no reference speed listed, mass about 2150 g.
Can a CARB bearing like C 2216 KV locate the shaft axially?
No — that is the defining feature. C 2216 KV 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 2216 KV designation read?
C = CARB toroidal family; 22 = dimension series; 16 = 80 mm bore (code 16 × 5); suffix KV selects tapered 1:12 bore for adapter (H) sleeve mounting, 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.
