How the 32232 model number is decoded

32232 is a single-row tapered roller bearing in the ISO 32200 dimension series: a separable cone-and-cup design for combined radial and one-direction axial load, listed by SKF in SKF catalogue PUB BU/P1 17000.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 160 mm bore; the 290 mm OD and 84 mm width follow the ISO 355 general plan. SKF lists the plain number as the basic execution; letter suffixes such as B denote a steeper contact angle and are different order numbers. Catalogue mass 23000 g for the 160×290×84 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. Note the minimum-axial-load requirement: at light radial load and high speed the rollers of 32232 must still be held into the rib contact, which is another reason the catalogue recommends paired mounting with controlled setting. Load system: the 934 kN basic dynamic rating C and 1400 kN static rating C0 give a C0/C balance of 1.50, and dividing C by the 160 mm bore yields 5.84 kN per millimetre of journal — a density metric that compares across families; the 132 kN fatigue limit Pu is the floor beneath which the adjusted-life calculation drops below acceptable L10 hours for a 160 mm shaft carrying variable duty.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 160 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 160 mm bore (290×84 mm) is a wider, higher-capacity section than 30232; do not substitute without re-checking shaft shoulder diameters and pair setting.
• At the 934 kN rating of 32232, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 2,200 r/min speed end and heavier preload only where moment stiffness dominates.
• Do not mix brands or executions inside one 32232 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.
• Never press both rings through the wrong element during fitting: force for an interference shaft seat goes through the cone only, or brinell marks on the 290 mm cup race release as noise within the first running hours.
• The 934/1400 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 32232 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32232 designation when purchasing and match the execution to the mounting arrangement.
