How the 32222-DF model number is decoded
Assembly datum check: verify the 112 mm width against the drawing before clamping — the width is the assembled result and the quickest field check that the correct execution of 32222-DF is on the shaft. When a matched /DF set like 32222-DF 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. Do not separate 32222-DF into single-bearing service stock — as individual bearings the components are not interchangeable with catalogue single-row executions because the rings are ground for the set.The SKF 32222/DF is a 110×200×112 mm matched tapered-roller set — two single-row bearings in face-to-face (X) matched pair arrangement, ground and shipped together with the axial clearance fixed at the factory.Numbering ties the set to its envelope: base 32222 fixes the 110 mm bore and 200 mm OD of each bearing, the /DF suffix fixes the arrangement and setting, and the catalogue 112 mm width is the combined pair dimension. 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 112 mm overall width of 32222-DF is the axial space the pair occupies. Dividing the pair C 842 kN by the 110 mm bore gives 7.65 kN per millimetre of journal for the complete arrangement — a density metric that compares matched sets across the face-to-face (X) matched pair family.
Typical equipment & failure modes
Common applications
- large process pump and compressor shafts
- rolling-mill auxiliary drives
- crane sheave and hoist gearboxes
- rolling-mill auxiliary drives
Known failure patterns
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- uneven load sharing in a pair when spacer faces are not parallel to the bore
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- brinelling from pressing the cone or cup home through the rollers
- grease degradation after long shelf storage without rotation or re-greasing
Selection pitfalls — read before you substitute
- Clamp the 32222-DF pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.
- Spacer faces must stay parallel within the set's own tolerance; a tilted spacer in 32222-DF concentrates reversing thrust on one bearing and shows up as one-sided raceway wear.
- Setting is built into 32222-DF; the classic field error is re-adjusting a matched pair as if it were two loose single bearings, which destroys the /DF clearance class.
- The 842/1140 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 32222/DF designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of 32222-DF?
The SKF 32222/DF is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 110 mm bore, 200 mm outer diameter and 112 mm overall width (4.331 × 7.874 × 4.409 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 842 kN, C0 1140 kN, fatigue load limit Pu 122 kN, reference speed 2,200 r/min, limiting speed 3,200 r/min, mass about 14.50 kg.
What does the /DF suffix on 32222-DF mean?
The base 32222 is the ISO 355 single-row bearing; the /DF 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 32222-DF for one bearing or the pair?
They are for the complete matched pair: C 842 kN dynamic and C0 1140 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 32222 table values.
Can 32222-DF 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.
