How the 32207-DF model number is decoded
A matched /DF set needs no setting adjustment at mounting: the clearance is built in; the assembler's job is clean seats, correct fits (k5 on a 35 mm rotating shaft) and square abutments.32207-DF 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.Numbering ties the set to its envelope: base 32207 fixes the 35 mm bore and 72 mm OD of each bearing, the /DF suffix fixes the arrangement and setting, and the catalogue 48.5 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 48.5 mm overall width of 32207-DF is the axial space the pair occupies. With a pair mass of 910 g across the 35×72×48.5 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. Material and manufacturing detail: the 910 g catalogue mass reflects through-hardened bearing steel machined to the listed envelope; ring roundness and width tolerance keep the mounted-setting scatter inside the catalogue class. When a matched /DF set like 32207-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.
Typical equipment & failure modes
Common applications
- differential and pinion drives
- pump and compressor shafts
- machine-tool spindles
- automotive and light-truck wheel hubs
Known failure patterns
- preload loss as the mounted pair relaxes, letting rollers skid and smear the raceways
- roller large-end smearing against the cone rib after EP lubricant film failure
- 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
- electrical pitting on VFD-driven shafts without grounding protection
Selection pitfalls — read before you substitute
- Setting is built into 32207-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.
- Setting is built into 32207-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.
- A matched /DF set is ground as one system: never separate the two bearings of 32207-DF or swap the spacer — the factory clearance is lost the moment the set is broken.
- The 139/156 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 32207/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 32207-DF?
The SKF 32207/DF is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 35 mm bore, 72 mm outer diameter and 48.5 mm overall width (1.378 × 2.835 × 1.909 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 139 kN, C0 156 kN, fatigue load limit Pu 17 kN, reference speed 6,300 r/min, limiting speed 9,500 r/min, mass about 0.91 kg.
What does the /DF suffix on 32207-DF mean?
The base 32207 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 32207-DF for one bearing or the pair?
They are for the complete matched pair: C 139 kN dynamic and C0 156 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 32207 table values.
Can 32207-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 (k5 on a rotating 35 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 35 mm bore.
