How the 32236 model number is decoded

For a 180 mm shaft carrying combined load, SKF lists 32236 under catalogue execution SKF 32236: one open single-row tapered roller bearing in the heavy section of the 32200 family.The code breaks down as type prefix 3 (tapered roller), series 22 (the heavy section), and bore code 36 = 180 mm; dimensions 180×320×91 mm therefore match the ISO 355 envelope. SKF lists the plain number as the basic execution; letter suffixes such as B denote a steeper contact angle and are different order numbers. The 150 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.52 C0/C balance shows this execution is tuned to thrust-heavy combined loads rather than pure radial running. Mounting practice for 32236: the rotating cone takes the interference fit (m6 on a 180 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 70.0 mm half-section ((320−180)/2) of this 32200-series unit places the roller large-end pitch diameter at roughly 250 mm, and the 91 mm axial width is split between cone (50 mm) and cup rib (41 mm) — a geometry that sets the contact angle and, with the 29500 g rotating cone mass, the critical speed at which cage-roller imbalance begins.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 180 mm bore the cone mass is high enough that cocking during mounting damages the cage and rib; guide the ring square, confirm seat contact around the full circumference, and re-check setting after the first thermal cycle of the paired set.
• The 322 series at 180 mm bore (320×91 mm) is a wider, higher-capacity section than 30236; do not substitute without re-checking shaft shoulder diameters and pair setting.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the 32236 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
• A single 32236 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.
• Shaft and housing fillets must clear the bearing chamfer so the 91 mm-wide cup seats square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
• The 1069/1630 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 32236 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32236 designation when purchasing and match the execution to the mounting arrangement.
