How the C4036-V model number is decoded
The CARB bearing C 4036 V combines the self-aligning behaviour of a spherical roller bearing with the axial freedom of a cylindrical bearing in one 180 mm bore, 280 mm outside diameter, 100 mm wide unit rated 1320 kN dynamic. The designation C 4036 V separates into C (CARB), 40 (dimension series), 36 (180 mm bore) and V (cylindrical bore for direct shaft fitting, full-complement V execution (no cage)); envelope 180×280×100 mm follows the ISO 15 plan. The V suffix denotes a full complement: the toroidal rollers fill the 100 mm space without a cage, raising C to 1320 kN but cutting the speed ceiling (no reference speed is listed) versus the caged size. Pairing rule: use the CARB bearing opposite one locating spherical or tapered bearing — never at both shaft ends — and check the locating bearing takes 100 % of the thrust, since C 4036 V deliberately carries none. Mounting: slide the bearing onto the 180 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
- heavy industrial gearbox layshafts used as the non-locating position
- winder and reel drums in paper and steel strip plants
- paper machine drying cylinders and calender rolls with long, thermally expanding shafts
- continuous-caster guide rolls and slab-caster segments under heat growth
Known failure patterns
- raceway spalling once the catalogue L10 life is exceeded or after sustained overload
- thermal preloading when a shaft is located at both ends and growth has nowhere to go
- PA66 cage (TN9) softening when the sustained temperature passes the polymer limit
- electrical erosion of raceways on VFD-driven shafts without grounding or insulation
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
Selection pitfalls — read before you substitute
- At 180 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 4036 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 180 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 quoted 1320/2120 kN ratings belong to this exact execution (C 4036 V); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
- The 1320/2120 kN ratings and 23500 g mass are SKF catalogue values transcribed from ch. 10.1 of PUB BU/P1 17000 (PDF table page 864); 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 4036 V?
A C 4036 V measures 180 mm bore × 280 mm outside diameter × 100 mm width (7.087 × 11.024 × 3.937 in). From SKF catalogue PUB BU/P1 17000: dynamic C 1320 kN, static C0 2120 kN, fatigue limit Pu 196 kN, limiting speed 430 r/min, no reference speed listed, mass about 23500 g.
Can a CARB bearing like C 4036 V locate the shaft axially?
No — that is the defining feature. C 4036 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 4036 V designation read?
C = CARB toroidal family; 40 = dimension series; 36 = 180 mm bore (code 36 × 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 (1320 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 4036 V is the cylindrical bore for direct shaft fitting, full-complement V execution (no cage).
