How the 32216-SKF model number is decoded
SKF 32216 (SKF 32216) is the heavy section tapered roller choice for a 80 mm shaft — one row of tapered rollers on an asymmetric raceway inside the 140×35.25 mm ISO 355 envelope.Reading the designation: the leading 3 marks a single-row tapered roller bearing, the 22 is the ISO 355 diameter/width series (heavy section), and the last two digits encode the 80 mm bore; the 140 mm OD and 35.25 mm width follow the ISO 355 general plan. In SKF suffix language a bare 32216 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. Catalogue mass 2050 g for the 80×140×35.25 mm open execution covers the pressed-steel cage and standard roller complement; sealed or special-clearance variants differ slightly in mass and carry their own order numbers. Because the contact line is tapered, one 32216 reacts thrust in a single direction; bidirectional shafts need an O or X pair, and a rotating cone on a 80 mm shaft typically takes a k5 seat with an H7 housing bore. Dimensional interchange map: within the 32200 series at 80 mm bore, the 140 mm OD and 35.25 mm width are fixed by the ISO 355 plan, so any same-code bearing from another brand shares the mounting envelope; the 30.0 mm section height distinguishes this family from a 302 or 322 of the same bore, and the 2050 g mass is the minimum—sealed or snap-ring executions add rotating weight above that catalogue baseline.
Typical equipment & failure modes
Common applications
- paper-machine and printing rolls
- construction machinery drives
- marine deck machinery shafts
- heavy industrial gearboxes and speed reducers
Known failure patterns
- cup or cone misalignment when the separable rings are not seated square during mounting
- loose cup rotation in the housing when the specified press fit is not achieved
- uneven load sharing in a pair when spacer faces are not parallel to the bore
- thermal preload runaway in an O-arrangement pair when inner-ring heat expands the setting
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- rib-roller contact scoring from loss of the EP additive film
Selection pitfalls — read before you substitute
- Mount the 80 mm bore 32216 by induction heating of the cone (max 120 °C — the pressed-steel cage sets the ceiling, not the steel); driving it home through the cup or rollers brinells the tapered raceway.
- The 322 series at 80 mm bore (140×35.25 mm) is a wider, higher-capacity section than 30216; do not substitute without re-checking shaft shoulder diameters and pair setting.
- At the 228 kN rating of 32216, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 4,500 r/min speed end and heavier preload only where moment stiffness dominates.
- Do not mix brands or executions inside one 32216 pair — matched sets are ground for a specific setting, and pairing a SKF basic unit with a different suffix variant will not share the setting evenly.
- Open 32216 units need application-supplied sealing and a defined EP lubricant supply; the roller-rib contact is the first to fail when the additive film breaks down.
- The 228/245 kN ratings are SKF catalogue 17000 values for the basic 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 and re-verify for critical drives.
- SKF lists several executions of 32216 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32216 designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
What are the dimensions and catalogue data of 32216?
The SKF 32216 is a single-row tapered roller bearing with 80 mm bore, 140 mm outer diameter and 35.25 mm width (3.15 × 5.512 × 1.388 in) per ISO 355. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 228 kN, C0 245 kN, fatigue load limit Pu 28.5 kN, reference speed 3,800 r/min, limiting speed 4,500 r/min, mass about 2050 g. It is an open, separable bearing with a pressed-steel cage.
How does the 32216 bore code work?
The last two digits of 32216 are bore code 16, so 16 × 5 = 80 mm bore. The 140 mm OD and 35.25 mm width come from the ISO 355 dimension-series plan, shared with other tapered bearings of the same code.
What do the 32216 series and basic execution designations mean?
The leading 3 marks a single-row tapered roller bearing; the second digit 22 is the ISO 355 series (heavy section). The SKF catalogue lists the ISO 355 dimension-series code after the bare number. A steeper-contact-angle variant (B suffix) is a different order number and is not interchangeable with the basic execution.
Can a single 32216 take axial load in both directions?
No — one single-row tapered roller bearing reacts thrust in one direction only, and under radial load its contact angle induces an axial force. Use two bearings as a matched pair: O (back-to-back) for a rigid, moment-resisting arrangement, X (face-to-face) where thermal expansion must be tolerated, or tandem where one-direction thrust is shared.
How does 32216 compare with a ball bearing of the same bore?
A tapered roller bearing has line contact and a steep contact angle: much higher combined axial-plus-radial capacity and shock resistance than a ball bearing of the same bore, at the cost of speed, one-direction thrust, mandatory pairing for reversing loads and a minimum axial load requirement. A ball bearing cannot be dropped into a combined-load 32216 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
