How the 32007X-DF model number is decoded
Material and manufacturing detail: the 460 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. Setting note for 32007X-DF: the axial clearance is set at the factory by selective spacer grinding for the /DF execution; in service, re-checking end play after the first thermal cycle catches seating relaxation before it becomes roller skid. Lubrication for the pair should be sized against the combined 36 mm width and 460 g mass: two roller sets sweep twice the contact area of a single bearing of the same bore.32007X-DF (SKF 32007 X/DF) is the face-to-face (X) matched pair matched-set choice for a 35 mm shaft: a pair of tapered roller bearings whose combined envelope is 62×36 mm, delivered ready to mount with controlled internal clearance.Numbering ties the set to its envelope: base 32007 X fixes the 35 mm bore and 62 mm OD of each bearing, the /DF suffix fixes the arrangement and setting, and the catalogue 36 mm width is the combined pair dimension. Face-to-face matching puts the small rib ends outward, so the pressure cones cross inside the pair; 32007X-DF therefore runs cooler where the shaft expands axially, at the price of lower moment stiffness than an O-arrangement of the same 35 mm bore. The C0/C balance of the pair is about 1.20; combined with the 11.6 kN fatigue limit this frames a set sized for reversing combined load on a 35 mm shaft rather than for pure radial duty.
Typical equipment & failure modes
Common applications
- automotive and light-truck wheel hubs
- industrial gearbox shafts and reducers
- differential and pinion drives
- industrial gearbox shafts and reducers
Known failure patterns
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- hard-particle indentation of the tapered raceway in unfiltered oil
- electrical pitting on VFD-driven shafts without grounding protection
Selection pitfalls — read before you substitute
- Replace 32007X-DF as a complete set: pairing a new bearing with a worn partner leaves the clearance undefined even when the designation matches.
- Spacer faces must stay parallel within the set's own tolerance; a tilted spacer in 32007X-DF concentrates reversing thrust on one bearing and shows up as one-sided raceway wear.
- Clamp the 32007X-DF pair axially through the cones, never through the rollers; pressing force across the roller complement brinells the raceways of both bearings at once.
- The 89.7/108 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 32007 X/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 32007X-DF?
The SKF 32007 X/DF is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 35 mm bore, 62 mm outer diameter and 36 mm overall width (1.378 × 2.441 × 1.417 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 89.7 kN, C0 108 kN, fatigue load limit Pu 11.6 kN, reference speed 7,000 r/min, limiting speed 10,000 r/min, mass about 0.46 kg.
What does the /DF suffix on 32007X-DF mean?
The base 32007 X 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 32007X-DF for one bearing or the pair?
They are for the complete matched pair: C 89.7 kN dynamic and C0 108 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 32007 X table values.
Can 32007X-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.
