SKF series 240 CCK30/W33 spherical roller bearings are double-row oscillating components designed to withstand high radial loads and angular misalignment. Their design with tapered bore and circumferential groove allows mounting with an adapter sleeve and lubrication through channels. They are used in industrial applications where shaft flexing or alignment errors require a robust, self-aligning bearing.
The designation of these bearings is interpreted as follows: 240 indicates the dimension series, which in this case is medium section; CC indicates the optimized internal design with centered roller guidance and stamped steel cage; K30 means tapered bore with 1:30 taper; and /W33 indicates the presence of a groove and lubrication holes in the outer ring. For example, 24026 CCK30/W33 corresponds to a bearing with a 130 mm bore diameter, while 24048 CCK30/W33 has 240 mm. These suffixes are key to selecting the appropriate mounting and lubrication system.
These bearings are used in equipment where loads are significant and misalignment may occur, such as conveyor belts, mills, crushers, vibrating screens, industrial fans and paper machines. In Argentina, they are common in the cement, mining and steel industries and in grain processing plants. Their self-aligning capability makes them suitable for long shafts that flex under load, and their robust construction withstands severe working conditions with proper maintenance.
To correctly select a bearing from these series, take into account the radial and axial load it must withstand, the rotation speed and the type of mounting. The K30 tapered bore requires an adapter sleeve or a shaft with a 1:30 taper; verify concentricity and tightening according to the manufacturer. Lubrication can be grease or oil; with W33 you can relubricate through the outer ring. It is essential to ensure correct initial alignment and to check the internal clearance after mounting to avoid overloads.
Regarding equivalents, spherical roller bearings with tapered bore and lubrication groove are manufactured under international standards, so different manufacturers offer products with similar designations. However, not all suffixes match exactly: for example, other manufacturers may use K for 1:12 taper or W33 for groove and holes. Always verify the critical dimensions and operating conditions before replacing one bearing with another brand. MR Accesorios Industriales sells SKF, which guarantees traceability and quality.

Frequently Asked Questions
- What are the dimensions of the SKF 24013 CCK30/W33 bearing?
- The SKF 24013 CCK30/W33 bearing has a 65 mm bore, a 100 mm outside diameter and a 35 mm width (65 x 100 x 35 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 24013.
- What does the K30 suffix mean in the designation?
- K30 indicates that the bearing has a tapered bore with 1:30 taper. This allows mounting on tapered shafts or with adapter sleeves, which makes it easier to adjust the internal clearance and to dismount.
- What is the W33 groove for?
- W33 indicates that the outer ring has a circumferential groove and lubrication holes. This allows more efficient relubrication of the bearing, especially in applications with high temperatures or difficult access.
- How do I choose between a bearing with tapered bore and one with cylindrical bore?
- The tapered bore makes mounting with a sleeve and adjustment of the radial clearance easier. If your shaft is cylindrical and you do not need to adjust the clearance, you can choose a bearing with a cylindrical bore. Ask us according to your equipment.
