How the 32216-DF model number is decoded
Ordering number SKF 32216/DF in SKF catalogue PUB BU/P1 17000 denotes two single-row tapered roller bearings supplied as a matched face-to-face (X) matched pair set for a 80 mm shaft — one order number, one factory setting.Digit by digit, 32216-DF reads as the ISO 355 base bearing 32216 supplied as a face-to-face (X) matched pair matched pair (/DF); the 80 mm bore and 140 mm OD are per-bearing, the 70.5 mm width is for the set. Face-to-face matching puts the small rib ends outward, so the pressure cones cross inside the pair; 32216-DF therefore runs cooler where the shaft expands axially, at the price of lower moment stiffness than an O-arrangement of the same 80 mm bore. Catalogue mass 4250 g covers both bearings and the ground spacer of 32216-DF; keep the set complete — substituting one bearing or a non-ground spacer destroys the factory clearance. Assembly datum check: verify the 70.5 mm width against the drawing before clamping — the width is the assembled result and the quickest field check that the correct execution of 32216-DF is on the shaft. Spacer discipline: the spacer between the two bearings of 32216-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. Do not separate 32216-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.
Typical equipment & failure modes
Common applications
- marine deck machinery shafts
- heavy industrial gearboxes and speed reducers
- large process pump and compressor shafts
- marine deck machinery shafts
Known failure patterns
- thermal preload runaway in an O-arrangement pair when inner-ring heat expands the setting
- thermal preload runaway in an O-arrangement pair when inner-ring heat expands the setting
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- hard-particle indentation of the tapered raceway in unfiltered oil
- mounting score marks when the cone is cocked over the shaft keyway or a burr
Selection pitfalls — read before you substitute
- A matched /DF set is ground as one system: never separate the two bearings of 32216-DF or swap the spacer — the factory clearance is lost the moment the set is broken.
- Spacer faces must stay parallel within the set's own tolerance; a tilted spacer in 32216-DF concentrates reversing thrust on one bearing and shows up as one-sided raceway wear.
- Setting is built into 32216-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 391/490 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 32216/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 32216-DF?
The SKF 32216/DF is a matched pair of single-row tapered roller bearings in face-to-face (X) matched pair arrangement with 80 mm bore, 140 mm outer diameter and 70.5 mm overall width (3.15 × 5.512 × 2.776 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 391 kN, C0 490 kN, fatigue load limit Pu 57 kN, reference speed 3,000 r/min, limiting speed 4,500 r/min, mass about 4.25 kg.
What does the /DF suffix on 32216-DF mean?
The base 32216 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 32216-DF for one bearing or the pair?
They are for the complete matched pair: C 391 kN dynamic and C0 490 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 32216 table values.
Can 32216-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 80 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 80 mm bore.
