How the 32022-SKF model number is decoded

32022 is a single-row tapered roller bearing in the ISO 32000 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 20 is the ISO 355 diameter/width series (low-friction section), and the last two digits encode the 110 mm bore; the 170 mm OD and 38 mm width follow the ISO 355 general plan. In SKF suffix language a bare 32022 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. At 3,000 r/min reference speed the 30.0 mm-section 32022 is governed thermally by preload and lubricant flow; grease or oil selection should be made against that value, with 3,600 r/min as the mechanical ceiling. Mounting practice for 32022: the rotating cone takes the interference fit (m6 on a 110 mm shaft), the cup slides for axial location, and reversing-thrust duty demands a paired O/X set rather than one bearing. Material and manufacturing detail: the 3050 g catalogue mass reflects through-hardened bearing steel (density ~7.85 g/cm³) machined to the 32000 ISO envelope, with the pressed-steel cage contributing roughly 92 g of the total; the 110 mm bore is ground to IT5 roundness and the 170 mm OD to IT5 cylindricity, and the 38 mm width tolerance keeps the pair-setting scatter within the ISO preload class.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 110 mm bore 32022 by induction heating of the cone (max 120 °C — the pressed-steel cage sets the ceiling, not the steel); driving it home through the cup or rollers brinells the tapered raceway.
• The 320 series at 110 mm bore (170×38 mm) is the low-friction, higher-speed section; it carries less thrust than a 30222 of the same bore, so verify the axial load share before swapping.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the 32022 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the 32022 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 3,000 r/min reference is a thermal criterion under load, while the 3,600 r/min limiting value is the mechanical ceiling — observe both.
• The 288/390 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 32022 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32022 X designation when purchasing and match the execution to the mounting arrangement.
