How the 24064-CCK30-W33 model number is decoded

For sleeve mounting on a 320 mm shaft, SKF order number SKF 24064 CCK30/W33 is the 1:30 tapered-bore spherical roller bearing in the 24000-series family (dimension series 40 (compact OD, maximum width)); the cylindrical-bore equivalent is a separate order number, 24064-cc-w33. Reading the designation: the leading 2 marks a spherical roller bearing, the 40 is the ISO 15 dimension series (dimension series 40 (compact OD, maximum width)), and the last two digits encode the 320 mm bore; the 480 mm OD and 160 mm width follow the ISO 15 general plan. Reading the suffix on 24064-cck30-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 24064-cc-w33. Catalogue mass 115000 g for the 320×480×160 mm open execution covers the two pressed-steel cages with a floating guide ring; tapered-bore and sealed variants differ in mass and carry their own order numbers. For shafts with a locating shoulder, use an AH withdrawal sleeve instead of an adapter sleeve: the bearing presses against the shoulder and the sleeve is drawn out for dismounting, making the 24064-cck30-w33 removable without an induction heater.

Typical equipment & failure modes

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 24000-series series at 320 mm bore (480×160 mm) packs maximum roller length into the smallest OD envelope — very high C0 for its size but the lowest speed ceiling; never swap it for a wider-OD 231 bearing without re-checking the housing bore and the speed margin.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 160 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.

• The 115000 g mass and 160 mm width mean abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the outer ring and concentrates load on one roller row of 24064-cck30-w33.
• The 2969/5100 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24064 CCK30/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.
