How the C4022-MB model number is decoded
In SKF catalogue PUB BU/P1 17000, C 4022 MB denotes a toroidal roller bearing whose 60 mm long rollers crown at both ends: the contact accepts angular misalignment while the ring positions float, which is why CARB bearings are specified at the free shaft end. SKF builds the CARB order number from size plus execution: the bare number C 4022 is the brass-caged cylindrical-bore bearing, K (or K30) makes the bore tapered for sleeve mounting, and the cage/seal letters follow — here MB. 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; the 2,600 r/min reference and 3,400 r/min limiting speed are both catalogue values. Selection arithmetic: C 430 kN against C0 655 kN gives a C0/C ratio of 1.52, and the 69.5 kN fatigue load limit Pu sets the contamination-adjusted life floor. Open executions accept relubrication — route it through the outer-ring groove on sizes that have one and purge stale grease at service intervals. Grease through the annular groove features where provided; on open executions feed lubricant past the long roller set at assembly, since the 60 mm wide cavity does not fill itself.
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
- roller-end and flange smearing after lubricant starvation at the long roller contacts
- 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
- hard-particle indentation where oil or grease filtration is inadequate
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
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.
- Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 4022 MB must float; the two are designed to be used as a pair.
- Never use C 4022 MB 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.
- Reference and limiting speeds are different limits: the 2,600 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 430/655 kN ratings and 5300 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
Which dimensions does the C 4022 MB have?
A C 4022 MB 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 430 kN, static C0 655 kN, fatigue limit Pu 69.5 kN, reference speed 2,600 r/min, limiting speed 3,400 r/min, mass about 5300 g.
What does C 4022 MB mean in SKF part numbering?
C marks CARB; 40 the dimension series; the size code gives 110 mm bore; MB is the execution (cylindrical bore for direct shaft fitting, machined inner-ring-guided brass cage (MB)). The envelope follows ISO 15 and matches spherical roller bearing outlines, but the functions differ.
Why is C 4022 MB used opposite a spherical roller bearing?
The spherical bearing locates the shaft and takes thrust; the CARB bearing at the other end self-aligns but floats, absorbing thermal expansion without inducing axial load. The pair is standard on paper machine drying cylinders and long caster rolls.
Is the C 4022 MB sealed?
No, it is an open execution relying on the housing seals; relubrication follows the groove/hole features of the size.
