How the 23032-CCK-W33 model number is decoded
SKF lists SKF 23032 CCK/W33 as the adapter-sleeve execution in the 23000-series range: a 160 mm nominal-bore spherical roller bearing whose 1:12 tapered inner ring is driven up a sleeve, with 240 mm OD and 60 mm width to the ISO 15 envelope. Reading the designation: the leading 2 marks a spherical roller bearing, the 30 is the ISO 15 dimension series (dimension series 30 (slim OD, extra-wide)), and the last two digits encode the 160 mm bore; the 240 mm OD and 60 mm width follow the ISO 15 general plan. 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 614 kN and C0 880 kN, the 23032-cck-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. Because driving up the 1:12 taper consumes radial clearance, K executions are commonly ordered with C3 initial clearance so the residual running clearance after mounting matches the cylindrical-bore 23032-cc-w33 on an interference seat.
Typical equipment & failure modes
Common applications
- heavy rolling-mill work-roll chocks
- large dredger and marine winch drums
- stepped shafts fitted with withdrawal sleeves against a fixed shoulder
- fan and pulley shafts that need periodic bearing removal in the field
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
- seal-lip wear and grease purge loss when an open bearing is run without functioning housing seals
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 23000-series series at 160 mm bore (240×60 mm) is the slim-OD envelope: it buys radial space but gives up capacity against a 222-series bearing of the same bore — confirm the L10 margin before downsizing into it.
- The 23032-cck-w33 and its cylindrical-bore counterpart 23032-cc-w33 share envelope and load ratings (614/880 kN) but are not interchangeable in a housing already fitted for direct shaft mounting — the sleeve changes the assembly stack-up.
- The 23032-cck-w33 and its cylindrical-bore counterpart 23032-cc-w33 share envelope and load ratings (614/880 kN) but are not interchangeable in a housing already fitted for direct shaft mounting — the sleeve changes the assembly stack-up.
- The 23032-cck-w33 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 614/880 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- The 614/880 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 23032 CCK/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 23032-cck-w33?
The SKF 23032 CCK/W33 is a double-row spherical roller bearing with a 1:12 tapered bore, 160 mm nominal bore, 240 mm outer diameter and 60 mm width (6.299 × 9.449 × 2.362 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 614 kN, C0 880 kN, Pu 83 kN, reference speed 2,400 r/min, limiting speed 3,000 r/min, mass about 14500 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K suffix mean on 23032-cck-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 23032-cck-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 160 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 23032-cck-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 23032-cck-w33 and 23032-cc-w33?
They share the ISO 15 envelope and the same 614/880 kN ratings, but 23032-cck-w33 has the 1:12 tapered bore for sleeve mounting on a plain shaft, while 23032-cc-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.
