How the 32207 model number is decoded

32207-XL belongs to the FAG single-row tapered roller range — the 35 mm bore entry in the 32200 series, dimensioned 72 mm OD and 24.25 mm wide to the ISO 355 boundary plan.The code breaks down as type prefix 3 (tapered roller), series 2 (the heavy section), and bore code 07 = 35 mm; dimensions 35×72×24.25 mm therefore match the ISO 355 envelope. In Schaeffler notation 32207-XL is the basic X-life execution; B-suffix variants have a steeper contact angle and are not interchangeable with the base bearing. The 13.7 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.01 C0/C balance shows this execution is tuned to thrust-heavy combined loads rather than pure radial running. Mounting practice for 32207: the rotating cone takes the interference fit (k5 on a 35 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 35 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 32207 pair heats, loses setting control and smears the roller-rib contact.
• The 322 series at 35 mm bore (72×24.25 mm) is a wider, higher-capacity section than 30207; do not substitute without re-checking shaft shoulder diameters and pair setting.
• A single 32207 cannot locate the shaft axially in both directions; mounting it singly on a reversing-thrust shaft leaves one direction uncontrolled — always use an O or X matched pair for bidirectional location.
• Do not mix brands or executions inside one 32207 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 32207 shares its ISO 355 envelope with other tapered bearings of the same code but is not a drop-in replacement for a ball bearing: it cannot run effectively under pure radial load without a minimum axial load, and a deep-groove bearing cannot replace its combined-load duty.
• The 84/85 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 32207 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.
