How the 32036X-DF model number is decoded
Numbering ties the set to its envelope: base 32036 X fixes the 180 mm bore and 280 mm OD of each bearing, the /DF suffix fixes the arrangement and setting, and the catalogue 128 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; 32036X-DF therefore runs cooler where the shaft expands axially, at the price of lower moment stiffness than an O-arrangement of the same 180 mm bore. Catalogue mass 29000 g covers both bearings and the ground spacer of 32036X-DF; keep the set complete — substituting one bearing or a non-ground spacer destroys the factory clearance. Journal and housing interface: the 180 mm bore takes a m6 shaft seat and the 280 mm outside diameter pairs with an H7 housing bore; the 128 mm width defines shoulder depth and the 29000 g mass is the dead load in thermal-growth calculations. Spacer discipline: the spacer between the two bearings of 32036X-DF is ground to the individual set — it carries a serial link to the pair, so never swap spacers between sets of the same designation. The rotating cones of 32036X-DF take a m6 seat on the 180 mm shaft; the cups are a transition-to-loose fit so the pair can be clamped to its factory setting during assembly.The SKF 32036 X/DF is a 180×280×128 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.
Typical equipment & failure modes
Common applications
- large industrial mixer shafts
- offshore winch and drawworks drums
- rolling-mill roll-neck bearings
- rolling-mill roll-neck bearings
Known failure patterns
- roller large-end smearing against the cone rib after EP lubricant film failure
- 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
- edge loading from shaft deflection or housing misalignment
- 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 32036X-DF concentrates reversing thrust on one bearing and shows up as one-sided raceway wear.
- Setting is built into 32036X-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 32036X-DF or swap the spacer — the factory clearance is lost the moment the set is broken.
- The 1360/2320 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 32036 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 32036X-DF?
The SKF 32036 X/DF is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 180 mm bore, 280 mm outer diameter and 128 mm overall width (7.087 × 11.024 × 5.039 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1360 kN, C0 2320 kN, fatigue load limit Pu 220 kN, reference speed 1,400 r/min, limiting speed 2,200 r/min, mass about 29.00 kg.
What does the /DF suffix on 32036X-DF mean?
The base 32036 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 32036X-DF for one bearing or the pair?
They are for the complete matched pair: C 1360 kN dynamic and C0 2320 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 32036 X table values.
Can 32036X-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 180 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 180 mm bore.
