How the 22232 model number is decoded
Ordering number 22232 CC/W33 in SKF catalogue PUB BU/P1 17000 denotes a double-row spherical roller bearing for a 160 mm shaft, dimension series 22 (medium OD, wide), with open execution and two pressed-steel cages with a floating guide ring. Digit by digit, 22232 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 22, and bore reference 32 resolving to 160 mm; 290 mm OD and 80 mm width are the matching ISO 15 boundary values. 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. The 65.0 mm radial section height ((290−160)/2) and 22500 g catalogue mass frame a 160 mm bore bearing rated at 1043 kN C — roughly 6.52 kN of dynamic capacity per millimetre of bore before application factors. A 160 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
Common applications
- wind-turbine main shaft support
- heavy rolling-mill work-roll chocks
- large dredger and marine winch drums
- steel-plant continuous-caster segments
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
- stamped-steel cage fatigue after long service in high-vibration screening duty without the VA405 execution
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- smearing on the roller-raceway contact during skid starts below the minimum load
Selection pitfalls — read before you substitute
- At 160 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 22200-series series at 160 mm bore (290×80 mm) is the general-purpose spherical roller envelope; stepping up to 223 adds capacity and width, stepping to 230 trims the OD — neither is interchangeable without re-checking shoulders and speed.
- The 22232 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 1043/1290 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- Catalogue reference speed and limiting speed are different limits: the 2,000 r/min reference is a thermal criterion under load, while the 2,800 r/min limiting value is the mechanical ceiling — observe both.
- The 1043/1290 kN ratings are SKF catalogue values for this exact execution (22232 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 22232 (cylindrical bore as listed, tapered-bore 22232 CCK/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22232 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22232?
The 22232 CC/W33 is a double-row spherical roller bearing with 160 mm bore, 290 mm outer diameter and 80 mm width (6.299 × 11.417 × 3.15 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1043 kN, C0 1290 kN, fatigue load limit Pu 118 kN, reference speed 2,000 r/min, limiting speed 2,800 r/min, mass about 22500 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 22232 bore code work?
The last two digits of 22232 are bore code 32, so 32 × 5 = 160 mm bore. The 290 mm OD and 80 mm width come from the ISO 15 dimension-series plan (dimension series 22 (medium OD, wide)), shared with other spherical roller bearings of the same code.
What does the CC/W33 suffix mean on 22232?
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 22232 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 22232K 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 22232 listed here seats directly on a machined journal.
