SKF 23240 CCK/W33 Spherical Roller Bearing

The SKF 23240 CCK/W33 is a heavy-duty double-row spherical roller bearing in SKF's 232 series, combining a tapered bore (1:12, suffix K) for adapter sleeve mounting with the CC symmetric roller geometry and a W33 lubrication groove and three holes in the outer ring for direct oil injection from the housing. With a bore of 200 mm, outer diameter of 360 mm, and width of 128 mm, the 23240 CCK/W33 is at home in the most demanding large-shaft applications in Saudi Arabia's oil and gas processing, power generation, and heavy industrial sectors — equipment categories where bearing failure means costly unplanned shutdowns with safety and environmental consequences.

The CC cage design and symmetric rollers in the 23240 CCK/W33 provide superior roller guidance and reduce heat generation compared to older asymmetric roller designs, enabling higher-speed capability relative to the bearing's size. The W33 ring groove and lubrication holes allow pressurised oil to be injected directly to the bearing's raceways from the housing — a lubrication method mandated by ARAMCO engineering standards for large bearings on critical rotating equipment, ensuring adequate film formation even under marginal start-up conditions or during momentary supply interruptions. This combination of features makes the 23240 CCK/W33 the specified bearing for large pump impeller shafts, marine propulsion equipment, large industrial fans, and heavy mill applications in the Kingdom.

SKF's manufacturing precision for the 23240 CCK/W33 delivers a basic dynamic load rating of 2,550 kN and a static load rating of 3,900 kN — among the highest in this bore size — reflecting the enhanced steel quality, roller profile accuracy, and raceway hardness depth control that define SKF Explorer class production. The bearing's ability to accommodate misalignment up to 1.5° means that thermal expansion differentials between a large steel shaft and a separate housing structure — common in process plant environments with wide temperature excursions — do not translate into destructive edge loading on the rollers.

Razz Middle East supplies the SKF 23240 CCK/W33 for large-bore bearing requirements across Saudi Arabia's petrochemical, power, and heavy industry sectors. These bearings are handled under strict storage and handling protocols to preserve the factory-level cleanliness essential for achieving rated life in critical service, and Razz provides full technical documentation, installation guidance, and adapter sleeve sourcing as part of the supply package.
