How the C4130-V model number is decoded
C 4130 V is the dimension series 41 CARB toroidal roller bearings member of the CARB range: 150 mm bore, 250 mm OD, 100 mm width, with the asymmetrical-looking toroidal roller set that defines the CARB principle. The designation C 4130 V separates into C (CARB), 41 (dimension series), 30 (150 mm bore) and V (cylindrical bore for direct shaft fitting, full-complement V execution (no cage)); envelope 150×250×100 mm follows the ISO 15 plan. The open execution relies on the housing seals and lubrication system, fed through groove/hole features on the large sizes. Explorer-class heat treatment and the crowned roller profile keep edge stress down when the 150 mm shaft deflects; no reference speed is listed and the limiting speed is 450 r/min. No thermal reference speed is listed for this full-complement execution; the mechanical limiting speed is 450 r/min. The full-complement V executions carry more load but list no thermal reference speed; the steel-caged executions run faster and cooler at light load. Mounting: slide the bearing onto the 150 mm seat or heat it (max 120 °C) and seat it square; never press through the 100 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
- 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
- abrasive paste forming as dust bypasses the housing seals into the open washer set
Selection pitfalls — read before you substitute
- At 150 mm bore, shaft expansion is already measurable: calculate the required float inside the 100 mm wide bearing rather than assuming the free-end clearance is "enough" at operating temperature.
- Never use C 4130 V 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 150 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 4130 V must float; the two are designed to be used as a pair.
- 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 1220/1860 kN ratings and 20000 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
What are the dimensions and ratings of the C 4130 V?
A C 4130 V measures 150 mm bore × 250 mm outside diameter × 100 mm width (5.906 × 9.843 × 3.937 in). From SKF catalogue PUB BU/P1 17000: dynamic C 1220 kN, static C0 1860 kN, fatigue limit Pu 176 kN, limiting speed 450 r/min, no reference speed listed, mass about 20000 g.
Can a CARB bearing like C 4130 V locate the shaft axially?
No — that is the defining feature. C 4130 V 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 4130 V designation read?
C = CARB toroidal family; 41 = dimension series; 30 = 150 mm bore (code 30 × 5); suffix V selects cylindrical bore for direct shaft fitting, 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 (1220 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 4130 V is the cylindrical bore for direct shaft fitting, full-complement V execution (no cage).
