How the 23292-CAK-W33 model number is decoded
SKF lists SKF 23292 CAK/W33 as the adapter-sleeve execution in the 23200-series range: a 460 mm nominal-bore spherical roller bearing whose 1:12 tapered inner ring is driven up a sleeve, with 830 mm OD and 296 mm width to the ISO 15 envelope. Digit by digit, 23292-cak-w33 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 32, and bore reference 92 resolving to 460 mm; 830 mm OD and 296 mm width are the matching ISO 15 boundary values. Note that K means 1:12 taper; the rarer K30 suffix means 1:30. Adapter sleeves (H) and withdrawal sleeves (AH) are ordered separately by shaft diameter, and the KM locknut plus MB lock washer used for drive-up are also separate components. With C 8958 kN and C0 13700 kN, the 23292-cak-w33 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. At 460 mm bore, dismount after service is by KM locknut reversal or a hydraulic nut on larger sizes; oil-injection grooves on the bigger sleeves let pressurised oil float the 23292-cak-w33 off the taper without scoring either surface.
Typical equipment & failure modes
Common applications
- heavy rolling-mill work-roll chocks
- large dredger and marine winch drums
- heavy crusher and screen shafts mounted and dismounted with hydraulic nuts
- long through-shafts in conveyors, where a sleeve seat avoids a precision journal
Known failure patterns
- raceway fatigue spalling of the sphered outer raceway after extended service above the catalogue L10 rating
- inner-ring raceway spalling from edge loading when misalignment exceeds the self-aligning recovery range
- sleeve seizure and shaft seat damage from omitting the anti-seize film between withdrawal sleeve and journal before drive-up
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- electrical pitting on VFD-driven shafts without grounding protection
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 23200-series series at 460 mm bore (830×296 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 296 mm width changes abutment spacing, even though the 830 mm OD matches.
- Never apply the drive-up or clearance-reduction figures for this 1:12 tapered 23292-cak-w33 to a bearing of the other taper (1:12 vs 1:30); the steeper taper moves far less clearance per nut turn and the targets come from different catalogue tables.
- The adapter sleeve is selected by actual shaft diameter, not by the 460 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 23292-cak-w33 with different sleeves.
- Shaft and housing fillets must clear the bearing chamfer so the 296 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- The 8958/13700 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 23292 CAK/W33); sleeve, KM nut and MB washer are separate order numbers, and the catalogue version (SKF catalogue PUB BU/P1 17000) should travel with the mounting specification.
Frequently asked questions
What are the dimensions and catalogue data of 23292-cak-w33?
The SKF 23292 CAK/W33 is a double-row spherical roller bearing with a 1:12 tapered bore, 460 mm nominal bore, 830 mm outer diameter and 296 mm width (18.11 × 32.677 × 11.654 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 8958 kN, C0 13700 kN, Pu 880 kN, reference speed 400 r/min, limiting speed 560 r/min, mass about 790000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K suffix mean on 23292-cak-w33?
K marks a 1:12 tapered bore for sleeve mounting — SKF writes EK or CCK(/W33), FAG writes -K- inside the suffix chain for sleeve mounting. The bearing seats on an H-series adapter sleeve with a KM locknut and MB lock washer (plain shaft, h9 tolerance), or on an AH withdrawal sleeve against a shaft shoulder. The rarer K30 suffix would instead mean a 1:30 taper; dimension series 40/41 spherical rollers commonly use it.
Which adapter sleeve fits the 23292-cak-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 460 mm nominal bore: SKF H-sleeve numbers each cover a small shaft-diameter range and are width-series specific (H39/H30/H31/H32 matching dimension series 39/40/31/32), and each kit bundles the sleeve, KM locknut and MB lock washer. For shoulder locations use an AH withdrawal sleeve instead. Confirm the sleeve number against the SKF catalogue PUB BU/P1 17000 mounting tables for your shaft size.
How is the 23292-cak-w33 driven up and checked?
Mounting is controlled by radial-clearance reduction or axial drive-up distance from the SKF catalogue tables for the 1:12 taper, never by locknut torque. Measure clearance with feeler gauges before and after tightening the KM nut, stop at the tabulated decrease, and lock the MB washer tab. Over-drive removes too much clearance (inner-ring cracking risk); under-drive lets the sleeve creep and fret.
What is the difference between 23292-cak-w33 and 23292-cak-w33?
They share the ISO 15 envelope and the same 8958/13700 kN ratings, but 23292-cak-w33 has the 1:12 tapered bore for sleeve mounting on a plain shaft, while 23292-cak-w33 has a cylindrical bore for direct mounting on a machined interference journal (typically m6 with H7 housing). They are separate order numbers, not interchangeable in the same shaft arrangement.
