How the 23192 model number is decoded

Ordering number 23192 CA/W33 in SKF catalogue PUB BU/P1 17000 denotes a double-row spherical roller bearing for a 460 mm shaft, dimension series 31 (medium OD, wide), with open execution and a one-piece machined brass cage guided on the inner ring (CA design). The code breaks down as type digit 2 (double-row spherical roller), dimension series 31 (dimension series 31 (medium OD, wide)), and bore code 92 = 460 mm; dimensions 460×760×240 mm therefore match the ISO 15 envelope. In SKF suffix language, CA/W33 means the brass-cage CA execution — often preferred for the largest bores and for shock/vibration duty where a rigid machined cage matters; W33 adds the relubrication groove. The sealed 2CS5 and vibrating-screen VA405 are separate executions. The 150.0 mm radial section height ((760−460)/2) and 440000 g catalogue mass frame a 460 mm bore bearing rated at 6760 kN C — roughly 14.70 kN of dynamic capacity per millimetre of bore before application factors. Spherical roller bearings are routinely specified with C3 clearance because the tight inner-ring fit and inner/outer temperature gradient eat into the CN running clearance — check the residual clearance after mounting with feeler gauges.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 460 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 23100-series series at 460 mm bore (760×240 mm) is the medium-OD wide envelope for heavy continuous duty; it is wider than a 222 bearing in the same OD class, so housing width and spacer stack must be re-checked before substitution.
• 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 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 6760/10800 kN ratings are SKF catalogue values for this exact execution (23192 CA/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 23192 (cylindrical bore as listed, tapered-bore 23192 CCK/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 23192 CA/W33 designation when purchasing.
