How the 32211-SKF model number is decoded

32211 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 55 mm bore; the 100 mm OD and 26.75 mm width follow the ISO 355 general plan. In SKF suffix language a bare 32211 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. Speed planning uses two different ceilings: 5,300 r/min thermal reference and 6,700 r/min mechanical limiting speed. Mounting practice for 32211: the rotating cone takes the interference fit (k5 on a 55 mm shaft), the cup slides for axial location, and reversing-thrust duty demands a paired O/X set rather than one bearing. Cross-section geometry: the 22.5 mm half-section ((100−55)/2) of this 32200-series unit places the roller large-end pitch diameter at roughly 77 mm, and the 26.75 mm axial width is split between cone (15 mm) and cup rib (12 mm) — a geometry that sets the contact angle and, with the 840 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 55 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 32211 pair heats, loses setting control and smears the roller-rib contact.
• The 322 series at 55 mm bore (100×26.75 mm) is a wider, higher-capacity section than 30211; do not substitute without re-checking shaft shoulder diameters and pair setting.
• Do not mix brands or executions inside one 32211 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.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the 32211 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
• Catalogue reference speed and limiting speed are different limits: the 5,300 r/min reference is a thermal criterion under load, while the 6,700 r/min limiting value is the mechanical ceiling — observe both.
• The 130/129 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 32211 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32211 designation when purchasing and match the execution to the mounting arrangement.
