How the C2215-V model number is decoded
SKF lists C 2215 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. Reading the code: C marks the CARB toroidal family, the first two digits (22) identify the ISO dimension series and the last two (15) encode the 75 mm bore; suffixes describe bore and execution. The cylindrical 75 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 75×130×31 mm are identical — only the mounting method changes. Selection arithmetic: C 220 kN against C0 240 kN gives a C0/C ratio of 1.09, and the 28 kN fatigue load limit Pu sets the contamination-adjusted life floor. Mounting: slide the bearing onto the 75 mm seat or heat it (max 120 °C) and seat it square; never press through the 31 mm roller set, and leave the free-end housing shoulder clear so axial float is unrestricted.
Typical equipment & failure modes
Common applications
- continuous-caster guide rolls and slab-caster segments under heat growth
- 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
Known failure patterns
- roller-end and flange smearing after lubricant starvation at the long roller contacts
- 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
- rolling-contact fatigue spalling after the catalogue L10 life is exhausted
- grease churning and overheating when a high-speed thrust position is over-packed
Selection pitfalls — read before you substitute
- At 75 mm bore the small CARB executions are unusually wide (31 mm) for their 130 mm OD — confirm the housing width before substituting a standard spherical bearing of the same bore.
- The quoted 220/240 kN ratings belong to this exact execution (C 2215 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.
- Tapered-bore K executions mount on adapter sleeves (1:12) and K30 on withdrawal sleeves (1:30) — the 75 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
- 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 220/240 kN ratings and 1650 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
Is the C 2215 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 2215 V have?
A C 2215 V measures 75 mm bore × 130 mm outside diameter × 31 mm width (2.953 × 5.118 × 1.22 in). From SKF catalogue PUB BU/P1 17000: dynamic C 220 kN, static C0 240 kN, fatigue limit Pu 28 kN, limiting speed 2,200 r/min, no reference speed listed, mass about 1650 g.
What does C 2215 V mean in SKF part numbering?
C marks CARB; 22 the dimension series; the size code gives 75 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.
