How the 24192-ECAK30-W33 model number is decoded
Ordering number SKF 24192 ECAK30/W33 in SKF catalogue PUB BU/P1 17000 is a double-row spherical roller bearing with a tapered bore (1:30), intended for an H-series adapter sleeve or AH withdrawal sleeve, with a one-piece machined brass cage guided on the inner ring (CA design) and the same 460×760×300 mm ISO 15 outline as its cylindrical-bore counterpart. Reading the designation: the leading 2 marks a spherical roller bearing, the 41 is the ISO 15 dimension series (dimension series 41 (medium OD, maximum width)), and the last two digits encode the 460 mm bore; the 760 mm OD and 300 mm width follow the ISO 15 general plan. Reading the suffix on 24192-ecak30-w33, the K30 (or EK/CCK30) element changes only the bore — 1:30 taper for sleeve mounting — while the rest of the suffix chain (CC cages with W33 groove) keeps the same internal design, cage and W33 relubrication features as the cylindrical-bore 24192-ecak30-w33. Selection arithmetic: the C0/C ratio is about 1.70 (static 14600 kN against dynamic 8608 kN), typical of a spherical roller sized for heavy combined loads, and the 1000 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. Mounting on the 1:30 taper is controlled by clearance reduction or measured axial drive-up, never by locknut torque: SKF tables give the target radial-clearance decrease for the 460 mm 24192-ecak30-w33, checked with feeler gauges before and after drive-up.
Typical equipment & failure modes
Common applications
- SAG and ball-mill drive shafts
- large mining crusher main 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
- smearing on the roller-raceway contact during skid starts below the minimum load
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 24100-series series at 460 mm bore (760×300 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 430 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
- Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24192-ecak30-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 24192-ecak30-w33 with different sleeves.
- The self-aligning feature is not a license to ignore alignment: beyond ≈ 0.5–2.5° (series-dependent) the edge loading eats the fatigue margin, and seal drag grows as the rings tilt.
- The 8608/14600 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24192 ECAK30/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 24192-ecak30-w33?
The SKF 24192 ECAK30/W33 is a double-row spherical roller bearing with a 1:30 tapered bore, 460 mm nominal bore, 760 mm outer diameter and 300 mm width (18.11 × 29.921 × 11.811 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 8608 kN, C0 14600 kN, Pu 1000 kN, reference speed 280 r/min, limiting speed 430 r/min, mass about 590000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K30 suffix mean on 24192-ecak30-w33?
K30 (written CCK30/W33 in the CC execution) marks the 1:30 tapered bore 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.
Which adapter sleeve fits the 24192-ecak30-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 24192-ecak30-w33 driven up and checked?
Mounting is controlled by radial-clearance reduction or axial drive-up distance from the SKF catalogue tables for the 1:30 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 24192-ecak30-w33 and 24192-ecak30-w33?
They share the ISO 15 envelope and the same 8608/14600 kN ratings, but 24192-ecak30-w33 has the 1:30 tapered bore for sleeve mounting on a plain shaft, while 24192-ecak30-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.
