How the 23224 model number is decoded

23224 CC/W33 belongs to the SKF spherical roller range — the 120 mm bore entry in the 23200-series series (dimension series 32 (medium OD, extra wide)), dimensioned 215 mm OD and 76 mm wide. The code breaks down as type digit 2 (double-row spherical roller), dimension series 32 (dimension series 32 (medium OD, extra wide)), and bore code 24 = 120 mm; dimensions 120×215×76 mm therefore match the ISO 15 envelope. In SKF suffix language, E marks the optimized high-capacity design and CC/W33 the pressed-steel-cage execution with relubrication groove; both are open bearings — the sealed variant carries the 2CS5 suffix and the vibrating-screen execution VA405. Catalogue mass 12000 g for the 120×215×76 mm open execution covers the two pressed-steel cages with a floating guide ring; tapered-bore and sealed variants differ in mass and carry their own order numbers. A 120 mm rotating inner ring usually runs m6 on the shaft with H7 in the housing; for vibrating-screen duty the outer ring is instead held tight and the shaft seat loosened — follow the screen builder's fit schedule.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 120 mm bore the ring mass makes cocking during mounting a real risk; guide the bearing square, confirm seat contact around the full circumference, and re-check the self-aligning swing after the housing cap is torqued down.
• The 23200-series series at 120 mm bore (215×76 mm) adds still more width for shock-loaded and vibratory loads; it does not interchange with a 231 bearing of the same bore because the 76 mm width changes abutment spacing, even though the 215 mm OD matches.
• The self-aligning feature is not a license to ignore alignment: beyond ≈ 0.5–2.5° (series-dependent) the edge loading eats the fatigue margin, and seal drag grows as the rings tilt.
• The 23224 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 732/930 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
• The 732/930 kN ratings are SKF catalogue values for this exact execution (23224 CC/W33); SKF can revise internal geometry without changing the order number, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the specification and re-verify for critical drives.
• SKF lists several executions of 23224 (cylindrical bore as listed, tapered-bore 23224 CCK/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 23224 CC/W33 designation when purchasing.
