How the 23252-CCK-W33 model number is decoded

The SKF 23252 CCK/W33 is a 260×480×174 mm spherical roller bearing with a 1:12 tapered bore — SKF catalogue execution for sleeve mounting on a 260 mm plain shaft, retaining the double-row self-aligning barrel-roller design. Reading the designation: the leading 2 marks a spherical roller bearing, the 32 is the ISO 15 dimension series (dimension series 32 (medium OD, extra wide)), and the last two digits encode the 260 mm bore; the 480 mm OD and 174 mm width follow the ISO 15 general plan. The K in the designation marks the 1:12 tapered bore: SKF mounts it on an H-series adapter sleeve (with KM locknut and MB lock washer) on a plain commercial-grade shaft, or on an AH withdrawal sleeve where the bearing must abut a shaft shoulder. With C 3395 kN and C0 4750 kN, the 23252-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. On an H adapter sleeve the 260 mm shaft seat only needs an h9 plain journal; slide the sleeve into the 23252-cck-w33 inner ring, tighten the KM nut against the MB washer until the catalogue clearance-reduction value is reached, then lock the washer tab.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 260 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 23200-series series at 260 mm bore (480×174 mm) adds still more width for shock-loaded and vibratory loads; it does not interchange with a 231 bearing of the same bore because the 174 mm width changes abutment spacing, even though the 480 mm OD matches.
• The adapter sleeve is selected by actual shaft diameter, not by the 260 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 23252-cck-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 174 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• The 160000 g mass and 174 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 23252-cck-w33.
• The 3395/4750 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 23252 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.
