Decoding SKF 24040 CCK30/W33
- 240Series
- Spherical roller bearings, 240 series. Series differ in outside diameter and width even when the bore is the same.
- 40Bore
- Bore 200 mm (40 × 5).
- CCK30/W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24040 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 24040 CCK30/W33 measures 200 mm across the bore and 310 mm across the outside diameter; its width is 109 mm (200 x 310 x 109 mm).

For equipment that combines heavy radial loads with shaft deflection or misalignment, SKF 240 CCK30/W33 spherical roller bearings are a common choice. These double-row self-aligning bearings feature a tapered bore and a lubrication groove in the outer ring, making them suitable for mounting with adapter sleeves and for relubrication in place.
Reading the designation helps you confirm fit and mounting method. The 240 portion identifies a medium-section dimension series. CC refers to the optimized internal design with centered roller guidance and a stamped steel cage. K30 means a tapered bore with 1:30 taper. W33 indicates a circumferential groove and lubrication holes in the outer ring. Bore sizes vary by part number: 24026 CCK30/W33 has a 130 mm bore, while 24048 CCK30/W33 has a 240 mm bore.
These bearings are found in conveyor systems, mills, crushers, vibrating screens, industrial fans and paper machines. They handle the flexing of long shafts and the misalignment that comes with heavy-duty operation. With proper maintenance, their robust construction suits demanding environments such as cement, mining, steel and grain processing.
Selection depends on radial and axial load, speed and mounting style. The K30 bore requires an adapter sleeve or a shaft with a 1:30 taper. Check concentricity and tightening according to the manufacturer’s instructions. Grease or oil lubrication is possible; W33 allows relubrication through the outer ring. Verify initial alignment and internal clearance after mounting to prevent overloads.
Spherical roller bearings with tapered bore and lubrication groove are made to international standards, so other brands may offer similar designations. However, suffixes can differ: some use K for a 1:12 taper or W33 for groove and holes. Always confirm critical dimensions and operating conditions before interchanging brands. MR supplies SKF bearings for traceability and quality.

Frequently asked questions
- SKF 24040 CCK30/W33 bearing: what are its dimensions?
- SKF 24040 CCK30/W33 measures 200 mm across the bore and 310 mm across the outside diameter; its width is 109 mm (200 x 310 x 109 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24040.
- What does the K30 suffix mean?
- K30 indicates a tapered bore with 1:30 taper. This allows mounting on tapered shafts or with adapter sleeves, simplifying internal clearance adjustment and dismounting.
- What is the purpose of the W33 groove?
- W33 means the outer ring has a circumferential groove and lubrication holes. This enables more efficient relubrication, particularly in high-temperature or hard-to-reach applications.
- How do I choose between a tapered bore and a cylindrical bore?
- A tapered bore facilitates mounting with a sleeve and radial clearance adjustment. If your shaft is cylindrical and you do not need clearance adjustment, a cylindrical bore may be suitable. Contact us with your equipment details.
