How the 24196-ECAK30-W33 model number is decoded

Ordering number SKF 24196 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 480×790×308 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 480 mm bore; the 790 mm OD and 308 mm width follow the ISO 15 general plan. Sleeve mounting is why the K30 execution exists: a plain h9-tolerance shaft is enough because the adapter sleeve supplies the precision seat, and the bearing is removable without pulling over an interference journal — a separate order number from the cylindrical-bore bearing, never a field conversion. The 155.0 mm radial section height ((790−480)/2) and 635000 g catalogue mass frame a 480 mm bore bearing rated at 9198 kN C — roughly 19.16 kN of dynamic capacity per millimetre of bore before application factors. 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 480 mm 24196-ecak30-w33, checked with feeler gauges before and after drive-up.

Typical equipment & failure modes

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 24100-series series at 480 mm bore (790×308 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 400 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
• The adapter sleeve is selected by actual shaft diameter, not by the 480 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 24196-ecak30-w33 with different sleeves.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 308 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• 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 9198/15600 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24196 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.
