How the 32022X-DFC200 model number is decoded
In the face-to-face (X) arrangement the load lines of the two bearings converge toward the shaft axis: the set tolerates shaft deflection and thermal growth better than a back-to-back pair, but is less stiff against overturning moments. The 76 mm overall width of 32022X-DFC200 is the axial space the pair occupies. With a pair mass of 6300 g across the 110×170×76 mm envelope, the set replaces what would otherwise be two separate bearings plus spacer grinding work — the factory setting is the engineering value being purchased. Dimensional interchange map: within its boundary plan the 110×170×76 mm envelope of 32022X-DFC200 is fixed, so shoulder, spacer and seal drawings can be dimensioned straight from the catalogue table. When a matched /DFC200 set like 32022X-DFC200 is replaced, replace the whole set: mixing a new bearing with a worn partner from the old set leaves the clearance and load sharing of the pair undefined. Lubrication for the pair should be sized against the combined 76 mm width and 6300 g mass: two roller sets sweep twice the contact area of a single bearing of the same bore.32022X-DFC200 is a matched pair of single-row tapered roller bearings arranged face-to-face (X) matched pair, supplied by SKF in SKF catalogue PUB BU/P1 17000 as one factory-set unit: the two bearings, spacers and setting are matched together and must not be mixed with other sets.The code breaks down as base bearing 32022 X plus matched-set suffix /DFC200: two bearings of the 110 mm bore size, paired face-to-face (X) matched pair, with the 76 mm overall width spanning the whole arrangement.
Typical equipment & failure modes
Common applications
- large process pump and compressor shafts
- rolling-mill auxiliary drives
- crane sheave and hoist gearboxes
- construction machinery drives
Known failure patterns
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- preload loss as the mounted pair relaxes, letting rollers skid and smear the raceways
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- rib-roller contact scoring from loss of the EP additive film
- hard-particle indentation of the tapered raceway in unfiltered oil
Selection pitfalls — read before you substitute
- Spacer faces must stay parallel within the set's own tolerance; a tilted spacer in 32022X-DFC200 concentrates reversing thrust on one bearing and shows up as one-sided raceway wear.
- Setting is built into 32022X-DFC200; the classic field error is re-adjusting a matched pair as if it were two loose single bearings, which destroys the /DFC200 clearance class.
- Setting is built into 32022X-DFC200; the classic field error is re-adjusting a matched pair as if it were two loose single bearings, which destroys the /DFC200 clearance class.
- The 494/780 kN ratings are SKF catalogue 17000 values for this execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification.
- Quote the full SKF 32022 X/DFC200 designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of 32022X-DFC200?
The SKF 32022 X/DFC200 is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 110 mm bore, 170 mm outer diameter and 76 mm overall width (4.331 × 6.693 × 2.992 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 494 kN, C0 780 kN, fatigue load limit Pu 80 kN, reference speed 2,400 r/min, limiting speed 3,600 r/min, mass about 6.30 kg.
What does the /DFC200 suffix on 32022X-DFC200 mean?
The base 32022 X is the ISO 355 single-row bearing; the /DFC200 suffix marks the matched-set execution — the arrangement (face-to-face (X)), the ground spacer and the factory-set axial clearance class. A matched set cannot be assembled from loose single bearings; quote the full designation when ordering.
Are the C and C0 ratings of 32022X-DFC200 for one bearing or the pair?
They are for the complete matched pair: C 494 kN dynamic and C0 780 kN static already include load sharing between the two bearings. Do not halve them for single-bearing checks, and do not compare them directly with the single-row 32022 X table values.
Can 32022X-DFC200 be adjusted like two loose tapered bearings?
No — the axial clearance is set at the factory by selective spacer grinding. Mounting work is limited to clean seats, correct fits (m6 on a rotating 110 mm shaft) and axial clamping through the cones; re-setting in the field destroys the matched clearance class.
When should a face-to-face (X) matched set be chosen?
Choose the face-to-face (X) set where the shaft grows thermally or alignment is imperfect — the converging load lines tolerate deflection. It is the default choice for wheel hubs and general gearbox shafts at the 110 mm bore.
