How the 24164-CCK30-W33 model number is decoded

The SKF 24164 CCK30/W33 is a 320×540×218 mm spherical roller bearing with a 1:30 tapered bore — SKF catalogue execution for sleeve mounting on a 320 mm plain shaft, retaining the double-row self-aligning barrel-roller design. Numbering ties the bearing to its envelope: 24164-cck30-w33 means spherical-roller type, dimension series 41, 320 mm bore — which is why the 540×218 mm outline swaps dimensionally with other ISO 15 bearings of the same code. 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. At 500 r/min reference speed the 110.0 mm-section 24164-cck30-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 700 r/min as the mechanical ceiling. Because driving up the 1:30 taper consumes radial clearance, K30 executions are commonly ordered with C3 initial clearance so the residual running clearance after mounting matches the cylindrical-bore 24164-cc-w33 on an interference seat.

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 24100-series series at 320 mm bore (540×218 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 700 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
• A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 218 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
• Never apply the drive-up or clearance-reduction figures for this 1:30 tapered 24164-cck30-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.
• Open spherical roller bearings rely on the housing seals; in screening or crusher duty a failed seal lets grit into the sphered raceway and the 24164-cck30-w33 pits long before its L10 life.
• The 4395/7100 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 24164 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.
