How the C2326-K-VE240 model number is decoded
C 2326 K/VE240 is the dimension series 23 CARB toroidal roller bearings member of the CARB range: 130 mm bore, 280 mm OD, 93 mm width, with the asymmetrical-looking toroidal roller set that defines the CARB principle. The designation C 2326 K/VE240 separates into C (CARB), 23 (dimension series), 130 mm (slash-size) (130 mm bore — bore 130 mm is written directly after the slash) and K/VE240 (tapered 1:12 bore for adapter (H) sleeve mounting, full-complement V execution (no cage)); envelope 130×280×93 mm follows the ISO 15 plan. The V suffix denotes a full complement: the toroidal rollers fill the 93 mm space without a cage, raising C to 980 kN but cutting the speed ceiling (no reference speed is listed) versus the caged size. Selection arithmetic: C 980 kN against C0 1220 kN gives a C0/C ratio of 1.24, and the 114 kN fatigue load limit Pu sets the contamination-adjusted life floor. Mounting: mount on the adapter (H) sleeve matched to the 1:12 tapered bore, drive up to the catalogue reduction and lock the nut; never press through the 93 mm roller set, and leave the free-end housing shoulder clear so axial float is unrestricted.
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
- roller skew and cage damage after the bearing is clamped solid between shaft and housing shoulders
- 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
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
Selection pitfalls — read before you substitute
- At 130 mm bore, shaft expansion is already measurable: calculate the required float inside the 93 mm wide bearing rather than assuming the free-end clearance is "enough" at operating temperature.
- Never use C 2326 K/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 130 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 2326 K/VE240 must float; the two are designed to be used as a pair.
- Reference and limiting speeds are different limits: the 2,400 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 980/1220 kN ratings and 27000 g mass are SKF catalogue values transcribed from ch. 10.1 of PUB BU/P1 17000 (PDF table page 862); 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 the C 2326 K/VE240 designation read?
C = CARB toroidal family; 23 = dimension series; 130 mm (slash-size) = 130 mm bore (the bore is written directly after the slash (no bore code)); suffix K/VE240 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.
What is the difference between V and TN9 CARB executions?
V is the full-complement execution with no cage — more rollers, higher C (980 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 2326 K/VE240 is the tapered 1:12 bore for adapter (H) sleeve mounting, full-complement V execution (no cage).
How is C 2326 K/VE240 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 2326 K/VE240?
A C 2326 K/VE240 measures 130 mm bore × 280 mm outside diameter × 93 mm width (5.118 × 11.024 × 3.661 in). From SKF catalogue PUB BU/P1 17000: dynamic C 980 kN, static C0 1220 kN, fatigue limit Pu 114 kN, reference speed 2,400 r/min, limiting speed 3,200 r/min, mass about 27000 g.
