How the 23220 model number is decoded

Ordering number 23220 CC/W33 in SKF catalogue PUB BU/P1 17000 denotes a double-row spherical roller bearing for a 100 mm shaft, dimension series 32 (medium OD, extra wide), with open execution and two pressed-steel cages with a floating guide ring. Reading the designation: the leading 2 marks a spherical roller bearing, the 32 is the ISO 15 dimension series (dimension series 32 (medium OD, extra wide)), and the last two digits encode the 100 mm bore; the 180 mm OD and 60.3 mm width follow the ISO 15 general plan. 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. With C 498 kN and C0 600 kN, the 23220 load check covers radial plus moderate axial in either direction — but below the minimum load the rollers skid, so verify P ≥ 0.01·C0 at the lightest operating point. Mount with the spherical bearing's self-alignment in mind: it compensates ≈ 0.5–2.5° of misalignment depending on series, but the shaft and housing seats still set the datum — a rotating inner ring on a 100 mm shaft typically takes a k5 seat with an H7 housing bore.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 100 mm bore 23220 by induction heating (max 120 °C) or oil injection — driving a bearing of this section home through the rollers brinells both raceways, and the damage only speaks up as vibration hours later.
• The 23200-series series at 100 mm bore (180×60.3 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 60.3 mm width changes abutment spacing, even though the 180 mm OD matches.
• The 23220 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 498/600 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
• Never use the tapered-bore EK/K variant's drive-up figures on this cylindrical-bore 23220; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
• The 498/600 kN ratings are SKF catalogue values for this exact execution (23220 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 23220 (cylindrical bore as listed, tapered-bore 23220 CCK/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 23220 CC/W33 designation when purchasing.
