How the 32207-SKF model number is decoded

SKF 32207 belongs to the SKF 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 22 (the heavy section), and bore code 07 = 35 mm; dimensions 35×72×24.25 mm therefore match the ISO 355 envelope. In SKF suffix language a bare 32207 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. The 8.5 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 0.96 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. Journal and housing interface: the 35 mm bore takes a k5 shaft seat (upper deviation ~0.070 mm for this diameter range) and the 72 mm outside diameter pairs with an H7 housing bore tolerance band of 72.000/72.020 mm; the 24.25 mm width defines the shoulder depth, and the 440 g cone-plus-cup assembly is the dead load on the shaft during thermal expansion calculations.

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 SKF 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 81.2/78 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 32207 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32207 designation when purchasing and match the execution to the mounting arrangement.
