How the 23196 model number is decoded
23196 CA/W33 belongs to the SKF spherical roller range — the 480 mm bore entry in the 23100-series series (dimension series 31 (medium OD, wide)), dimensioned 790 mm OD and 248 mm wide. On the SKF nameplate, 23196 follows the ISO 15 convention: 2 for the spherical roller type, 31 for the dimension series 31 (medium OD, wide), final digits 96 for the 480 mm bore. 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. With C 7362 kN and C0 12000 kN, the 23196 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. The cylindrical-bore execution here seats directly on the shaft journal; if the application calls for an adapter sleeve, order the tapered-bore 23196 CCK/W33 variant instead and measure the drive-up or clearance reduction, not the nut torque.
Typical equipment & failure modes
Common applications
- heavy rolling-mill work-roll chocks
- large dredger and marine winch drums
- steel-plant continuous-caster segments
- large induced-draft fan rotors
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
- cage pocket wear or fracture from roller skew at insufficient minimum load or rapid acceleration
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- smearing on the roller-raceway contact during skid starts below the minimum load
Selection pitfalls — read before you substitute
- At 480 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 480 mm bore (790×248 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.
- Shaft and housing fillets must clear the bearing chamfer so the 248 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- Shaft and housing fillets must clear the bearing chamfer so the 248 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- The 7362/12000 kN ratings are SKF catalogue values for this exact execution (23196 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 23196 (cylindrical bore as listed, tapered-bore 23196 CCK/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 23196 CA/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 23196?
The 23196 CA/W33 is a double-row spherical roller bearing with 480 mm bore, 790 mm outer diameter and 248 mm width (18.898 × 31.102 × 9.764 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 7362 kN, C0 12000 kN, fatigue load limit Pu 780 kN, reference speed 400 r/min, limiting speed 750 r/min, mass about 485000 g. It is an open, self-aligning bearing with a one-piece machined brass cage guided on the inner ring (CA design).
How does the 23196 bore code work?
The last two digits of 23196 are bore code 96, so 96 × 5 = 480 mm bore. The 790 mm OD and 248 mm width come from the ISO 15 dimension-series plan (dimension series 31 (medium OD, wide)), shared with other spherical roller bearings of the same code.
What does the CA/W33 suffix mean on 23196?
CC denotes two pressed-steel cages with a floating guide ring between the roller rows, and W33 adds an annular groove plus three lubrication holes in the outer ring for relubrication. CCK/W33 is the 1:12 tapered-bore counterpart.
Can 23196 accommodate misalignment and axial load?
Yes on both counts. The sphered outer raceway lets the bearing self-align ≈ 0.5–2.5° depending on series, absorbing shaft deflection and housing-seat errors. The two barrel-roller rows also carry bidirectional axial load in addition to heavy radial load — this is the key difference from cylindrical roller bearings, which take no axial load.
When should the tapered-bore 23196K variant be used instead?
Choose the K (1:12 tapered bore) variant when the bearing must seat on an adapter or withdrawal sleeve — typical for long shafts, frequent dismounting, or stepped shafts where machining a precision journal is impractical. Sleeve mounting requires measuring clearance reduction or axial drive-up, not nut torque. The cylindrical-bore 23196 listed here seats directly on a machined journal.
