How the 23164-CCK-W33 model number is decoded
Ordering number SKF 23164 CCK/W33 in SKF catalogue PUB BU/P1 17000 is a double-row spherical roller bearing with a tapered bore (1:12), intended for an H-series adapter sleeve or AH withdrawal sleeve, with two pressed-steel cages with a floating guide ring and the same 320×540×176 mm ISO 15 outline as its cylindrical-bore counterpart. Reading the designation: the leading 2 marks a spherical roller bearing, the 31 is the ISO 15 dimension series (dimension series 31 (medium OD, wide)), and the last two digits encode the 320 mm bore; the 540 mm OD and 176 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. At 850 r/min reference speed the 110.0 mm-section 23164-cck-w33 is governed thermally by lubricant flow through the W33 groove and the two-row roller complement; grease or oil selection should be made against that value, with 1,100 r/min as the mechanical ceiling. 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 23164-cc-w33 on an interference seat.
Typical equipment & failure modes
Common applications
- large induced-draft fan rotors
- SAG and ball-mill drive shafts
- 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
- seal-lip wear and grease purge loss when an open bearing is run without functioning housing seals
Selection pitfalls — read before you substitute
- At 320 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 320 mm bore (540×176 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.
- Never apply the drive-up or clearance-reduction figures for this 1:12 tapered 23164-cck-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 23164-cck-w33 and its cylindrical-bore counterpart 23164-cc-w33 share envelope and load ratings (3923/6000 kN) but are not interchangeable in a housing already fitted for direct shaft mounting — the sleeve changes the assembly stack-up.
- Never use the tapered-bore EK/K variant's drive-up figures on this cylindrical-bore 23164-cck-w33; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 3923/6000 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 23164 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 23164-cck-w33?
The SKF 23164 CCK/W33 is a double-row spherical roller bearing with a 1:12 tapered bore, 320 mm nominal bore, 540 mm outer diameter and 176 mm width (12.598 × 21.26 × 6.929 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 3923 kN, C0 6000 kN, Pu 440 kN, reference speed 850 r/min, limiting speed 1,100 r/min, mass about 185000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K suffix mean on 23164-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 23164-cck-w33?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 320 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 23164-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 23164-cck-w33 and 23164-cc-w33?
They share the ISO 15 envelope and the same 3923/6000 kN ratings, but 23164-cck-w33 has the 1:12 tapered bore for sleeve mounting on a plain shaft, while 23164-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.
