How the 32016-SKF model number is decoded

The SKF 32016 X is a 80×125×29 mm single-row tapered roller bearing — the low-friction section entry in the 32000 series, with an asymmetric raceway cut for thrust capacity and separable mounting.Numbering ties the bearing to its envelope: 32016 means tapered-roller type 3, low-friction section series 20, 80 mm bore — which is why the 125×29 mm outline swaps dimensionally with other ISO 355 bearings of the same code. In SKF suffix language a bare 32016 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. At 4,000 r/min reference speed the 22.5 mm-section 32016 is governed thermally by preload and lubricant flow; grease or oil selection should be made against that value, with 5,000 r/min as the mechanical ceiling. Because the contact line is tapered, one 32016 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. Load system: the 168 kN basic dynamic rating C and 216 kN static rating C0 give a C0/C balance of 1.29, and dividing C by the 80 mm bore yields 2.10 kN per millimetre of journal — a density metric that compares across families; the 24.5 kN fatigue limit Pu is the floor beneath which the adjusted-life calculation drops below acceptable L10 hours for a 80 mm shaft carrying variable duty.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 80 mm bore 32016 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 320 series at 80 mm bore (125×29 mm) is the low-friction, higher-speed section; it carries less thrust than a 30216 of the same bore, so verify the axial load share before swapping.
• A single 32016 cannot locate the shaft axially in both directions; mounting it singly on a reversing-thrust shaft leaves one direction uncontrolled — always use an O or X matched pair for bidirectional location.
• At the 168 kN rating of 32016, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 5,000 r/min speed end and heavier preload only where moment stiffness dominates.
• Shaft and housing fillets must clear the bearing chamfer so the 29 mm-wide cup seats square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
• The 168/216 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 32016 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32016 X designation when purchasing and match the execution to the mounting arrangement.
