Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| C4022-2CS5V-GEM9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 110×170×60 mm envelope, but catalogue C/C0 differ between the cylindrical-bore full-complement V and cylindrical-bore sealed full-complement V executions (500/800 kN vs 415/585 kN) — envelope match, not a load-rating equivalent. |
| C4022-MB | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 110×170×60 mm envelope, but catalogue C/C0 differ between the cylindrical-bore full-complement V and cylindrical-bore MB inner-ring-guided brass-caged executions (500/800 kN vs 430/655 kN) — envelope match, not a load-rating equivalent. |
| 24022 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 110×170×60 mm envelope as the SKF spherical roller bearing SKF 24022 CC/W33, but catalogue C/C0 differ (500/800 kN vs 437/620 kN) — and the functions differ: spherical locates axially, CARB floats. Pair them; never swap one-for-one. |

How the C4022-V model number is decoded
C 4022 V is a CARB toroidal roller bearing to ISO 15: a single row of long, symmetrical barrel-shaped rollers between guide flanges, sized 110×170×60 mm, as listed in SKF catalogue PUB BU/P1 17000 ch. 10.1. In C 4022 V the 40 dimension series fixes the 170 mm OD and 60 mm width around the 110 mm bore (code 22 × 5); the suffix V then selects the cylindrical bore for direct shaft fitting, full-complement V execution (no cage). 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 110 mm shaft deflects; no reference speed is listed and the limiting speed is 1,200 r/min. The 5200 g mass over the 110×170×60 mm envelope yields about 4.55 kN dynamic per millimetre of bore — the long toroidal rollers give this family its radial capacity density. Seat tolerances follow the ISO 15 recommendation for the normal-load position — the 170 mm outer ring typically takes a loose housing fit to preserve float, and the rings must be supported across their full faces.
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
- edge loading and premature spalling when the CARB position is blocked from its designed axial float
- brass cage pocket wear under marginal lubrication in the large-bore M/MB executions
- false brinelling and rust-red witness marks on standby machines under external vibration
- grease churning and overheating when a high-speed thrust position is over-packed
Selection pitfalls — read before you substitute
- At 110 mm bore, shaft expansion is already measurable: calculate the required float inside the 60 mm wide bearing rather than assuming the free-end clearance is "enough" at operating temperature.
- 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.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 4022 V must float; the two are designed to be used as a pair.
- The quoted 500/800 kN ratings belong to this exact execution (C 4022 V); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
- Never use C 4022 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.
- The 500/800 kN ratings and 5200 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 are the dimensions and ratings of the C 4022 V?
A C 4022 V measures 110 mm bore × 170 mm outside diameter × 60 mm width (4.331 × 6.693 × 2.362 in). From SKF catalogue PUB BU/P1 17000: dynamic C 500 kN, static C0 800 kN, fatigue limit Pu 85 kN, limiting speed 1,200 r/min, no reference speed listed, mass about 5200 g.
Can a CARB bearing like C 4022 V locate the shaft axially?
No — that is the defining feature. C 4022 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 4022 V designation read?
C = CARB toroidal family; 40 = dimension series; 22 = 110 mm bore (code 22 × 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 (500 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 4022 V is the cylindrical bore for direct shaft fitting, full-complement V execution (no cage).
