How the C6915-V-VE240 model number is decoded
In SKF catalogue PUB BU/P1 17000, C 6915 V/VE240 denotes a toroidal roller bearing whose 54 mm long rollers crown at both ends: the contact accepts angular misalignment while the ring positions float, which is why CARB bearings are specified at the free shaft end. SKF builds the CARB order number from size plus execution: the bare number C 6915 is the full-complement cylindrical-bore bearing, K (or K30) makes the bore tapered for sleeve mounting, and the cage/seal letters follow — here V/VE240. The V suffix denotes a full complement: the toroidal rollers fill the 54 mm space without a cage, raising C to 204 kN but cutting the speed ceiling (no reference speed is listed) versus the caged size. Float capacity is a selection criterion: the catalogue lists the permissible axial displacement (s) for the 54 mm wide set; size the free-end housing so thermal growth stays within it, not just inside the overall width. 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
- 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
- roller-end and flange smearing after lubricant starvation at the long roller contacts
- 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
- hard-particle indentation where oil or grease filtration is inadequate
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
Selection pitfalls — read before you substitute
- At 75 mm bore the small CARB executions are unusually wide (54 mm) for their 105 mm OD — confirm the housing width before substituting a standard spherical bearing of the same bore.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 6915 V/VE240 must float; the two are designed to be used as a pair.
- Never use C 6915 V/VE240 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 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 204/325 kN ratings and 1400 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 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 6915 V/VE240 have?
A C 6915 V/VE240 measures 75 mm bore × 105 mm outside diameter × 54 mm width (2.953 × 4.134 × 2.126 in). From SKF catalogue PUB BU/P1 17000: dynamic C 204 kN, static C0 325 kN, fatigue limit Pu 37.5 kN, limiting speed 1,900 r/min, no reference speed listed, mass about 1400 g.
What does C 6915 V/VE240 mean in SKF part numbering?
C marks CARB; 69 the dimension series; the size code gives 75 mm bore; V/VE240 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.
Why is C 6915 V/VE240 used opposite a spherical roller bearing?
The spherical bearing locates the shaft and takes thrust; the CARB bearing at the other end self-aligns but floats, absorbing thermal expansion without inducing axial load. The pair is standard on paper machine drying cylinders and long caster rolls.
