How the 32211 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 FAG in Schaeffler HR1 (2022 edition).Reading the designation: the leading 3 marks a single-row tapered roller bearing, the 2 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 Schaeffler notation 32211-XL is the basic X-life execution; B-suffix variants have a steeper contact angle and are not interchangeable with the base bearing. Speed planning uses two different ceilings: 4,100 r/min thermal reference and 8,700 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.

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 FAG 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 4,100 r/min reference is a thermal criterion under load, while the 8,700 r/min limiting value is the mechanical ceiling — observe both.
• The 130/137 kN ratings are Schaeffler HR1 values for the X-life execution; the -XL suffix denotes the premium grade and is part of the order designation, so quote it in full when purchasing.
• Schaeffler lists 32211 in the X-life basic execution; variant executions with -B or other suffixes are separate order numbers and are not interchangeable with the basic X-life bearing.
