SKF SPHER ROLLER BEARING 24038 CCK30/W33

Self-aligning roller bearings play a key role in the proper functioning of equipment subjected to high mechanical loads. Their robust design ensures reliable and continuous performance, even under unstable or demanding operating conditions.

This SKF spherical roller bearing is designed to withstand high radial and axial loads while compensating for misalignment and shaft deflection. It features a 1:30 tapered bore (K30), a CC-type design, and an annular groove with three lubrication holes (W33), which together ensure increased robustness and stability under demanding operating conditions.

Features:
This self-aligning bearing features two symmetrical rows of rollers, providing high load capacity and excellent shock resistance. Its two windowed cages made of stamped steel sheet (CC design) ensure uniform load distribution and enhanced mechanical stability. They also limit inertial forces and promote smooth operation, even during speed variations or acceleration. The standard radial clearance ensures constant dynamic stability and allows the bearing to withstand high rotational speeds without the risk of overheating. Finally, the 1:30 tapered bore (K30) facilitates precise mounting on the shaft, allowing for optimal adjustment of the internal clearance. In fact, this type of bore is designed for highly precise installations, often using a locking collar, making it particularly well-suited for heavy-duty industrial environments.

Maintenance:
To maintain bearing performance, regular relubrication is essential, especially in environments exposed to contaminants. Thanks to the W33 configuration, this bearing features an annular groove and three lubrication holes that facilitate even lubricant distribution and enable efficient in-service maintenance. The absence of integrated seals requires special attention to cleanliness during maintenance operations. It is recommended to thoroughly clean the housing and external components before relubrication to prevent the ingress of harmful particles. Selecting a lubricant suitable for the operating conditions—particularly in terms of temperature—is crucial for ensuring optimal performance and extending the bearing’s service life.

Sealing:
This self-aligning roller bearing has an open design with no built-in seals, making it more vulnerable to external contaminants such as dust and moisture. However, this design facilitates visual inspection and maintenance operations. It is therefore essential to ensure that the installation areas and surrounding equipment are kept clean to prevent contamination and ensure the bearing operates properly.
