How the 32226 model number is decoded

The SKF 32226 is a 130×230×67.75 mm single-row tapered roller bearing — the heavy section entry in the 32200 series, with an asymmetric raceway cut for thrust capacity and separable mounting.Numbering ties the bearing to its envelope: 32226 means tapered-roller type 3, heavy section series 22, 130 mm bore — which is why the 230×67.75 mm outline swaps dimensionally with other ISO 355 bearings of the same code. In SKF suffix language a bare 32226 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. The 85 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.41 C0/C balance shows this execution is tuned to thrust-heavy combined loads rather than pure radial running. Specify pairs rather than single units wherever thrust reverses: the tapered contact of 32226 generates an induced axial load under radial force, and an unpaired bearing on a reversing shaft will run slack and fret its seat. Load system: the 590 kN basic dynamic rating C and 830 kN static rating C0 give a C0/C balance of 1.41, and dividing C by the 130 mm bore yields 4.54 kN per millimetre of journal — a density metric that compares across families; the 85 kN fatigue limit Pu is the floor beneath which the adjusted-life calculation drops below acceptable L10 hours for a 130 mm shaft carrying variable duty.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 130 mm bore the cone mass is high enough that cocking during mounting damages the cage and rib; guide the ring square, confirm seat contact around the full circumference, and re-check setting after the first thermal cycle of the paired set.
• The 322 series at 130 mm bore (230×67.75 mm) is a wider, higher-capacity section than 30226; do not substitute without re-checking shaft shoulder diameters and pair setting.
• Do not mix brands or executions inside one 32226 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.
• O (back-to-back) pairs are stiffer against moments, X (face-to-face) pairs tolerate misalignment and thermal growth better; choosing the arrangement from the 2D drawing rather than the actual shaft thermal expansion is a common 32226 mounting error.
• The pressed-steel cage is rated for standard industrial service; sustained running above the limiting speed or with degraded lubricant wears the cage pockets — inspect the cage at every relubrication interval.
• The 590/830 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 32226 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32226 designation when purchasing and match the execution to the mounting arrangement.
