How the 32206-SKF model number is decoded

In SKF catalogue PUB BU/P1 17000, 32206 appears as SKF 32206: an open, single-row tapered roller bearing in the heavy section of the 32200 dimension series, supplied with a pressed-steel cage as standard.On the SKF nameplate, 32206 follows the ISO 355 convention: 3 for the tapered-roller type, 22 for the heavy section, final digits 06 for the 30 mm bore. In SKF suffix language a bare 32206 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. With C 61.8 kN and C0 57 kN, the 32206 pair-sizing check is dominated by the axial share: keep the equivalent load P below the rating at the required L10, remembering one bearing alone cannot cover reversing thrust at 11,000 r/min. For a 30 mm shaft the usual cone seat is k5 with an H7 housing when the inner ring rotates; arrange two 32206 bearings as a set for two-direction location and set clearance from the load diagram, never from assembly feel. Cross-section geometry: the 16.0 mm half-section ((62−30)/2) of this 32200-series unit places the roller large-end pitch diameter at roughly 46 mm, and the 21.25 mm axial width is split between cone (12 mm) and cup rib (10 mm) — a geometry that sets the contact angle and, with the 290 g rotating cone mass, the critical speed at which cage-roller imbalance begins.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• On this 30 mm bore, interference and temperature rise consume clearance inside a preloaded pair; calculate the residual clearance after mounting and at operating temperature — an over-tight 32206 pair heats, loses setting control and smears the roller-rib contact.
• The 322 series at 30 mm bore (62×21.25 mm) is a wider, higher-capacity section than 30206; do not substitute without re-checking shaft shoulder diameters and pair setting.
• Setting is a design value, not an assembly feel: excessive preload in the 32206 pair raises operating temperature and can trigger thermal runaway, while too little lets the rollers skid and smear the raceway under light load.
• When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of 32206 pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
• Catalogue reference speed and limiting speed are different limits: the 9,000 r/min reference is a thermal criterion under load, while the 11,000 r/min limiting value is the mechanical ceiling — observe both.
• The 61.8/57 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 32206 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32206 designation when purchasing and match the execution to the mounting arrangement.
