How the C4022-2CS5V-GEM9 model number is decoded
For long shafts that grow thermally, SKF supplies C 4022-2CS5V/GEM9: the toroidal rollers allow the 110 mm inner ring to displace axially without induced thrust, while still accommodating shaft deflection like a spherical bearing. In C 4022-2CS5V/GEM9 the 40 dimension series fixes the 170 mm OD and 60 mm width around the 110 mm bore (the bore is written directly after the slash (no bore code)); the suffix 2CS5V/GEM9 then selects the cylindrical bore for direct shaft fitting, 2CS5V/GEM9 sealed full-complement execution with annular groove. The 2CS5V/GEM9 execution adds nitrile contact seals on both sides plus an annular-groove relubrication feature and a high-viscosity grease fill; the full-complement rollers keep 415 kN dynamic at a reduced 85 r/min ceiling. The 4600 g mass over the 110×170×60 mm envelope yields about 3.77 kN dynamic per millimetre of bore — the long toroidal rollers give this family its radial capacity density. 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
- 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
- vibrating screen exciters fitted with the VE240 tolerance execution
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
- PA66 cage (TN9) softening when the sustained temperature passes the polymer limit
- brinelling of washer raceways from impact or mounting force applied through the rolling elements
- abrasive paste forming as dust bypasses the housing seals into the open washer set
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.
- 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 415/585 kN ratings belong to this exact execution (C 4022-2CS5V/GEM9); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
- Never use C 4022-2CS5V/GEM9 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 110 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
- The 415/585 kN ratings and 4600 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
How is C 4022-2CS5V/GEM9 mounted?
Slide or heat (max 120 °C) the bearing onto the 110 mm seat, give the outer ring a loose housing fit, leave the float travel unobstructed, and never press through the 60 mm roller set.
What are the dimensions and ratings of the C 4022-2CS5V/GEM9?
A C 4022-2CS5V/GEM9 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 415 kN, static C0 585 kN, fatigue limit Pu 63 kN, limiting speed 85 r/min, no reference speed listed, mass about 4600 g.
Can a CARB bearing like C 4022-2CS5V/GEM9 locate the shaft axially?
No — that is the defining feature. C 4022-2CS5V/GEM9 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 4022-2CS5V/GEM9 designation read?
C = CARB toroidal family; 40 = dimension series; 110 mm (slash-size) = 110 mm bore (the bore is written directly after the slash (no bore code)); suffix 2CS5V/GEM9 selects cylindrical bore for direct shaft fitting, 2CS5V/GEM9 sealed full-complement execution with annular groove. K is a 1:12 tapered bore for an adapter sleeve, K30 a 1:30 bore for a withdrawal sleeve.
