SKF SPHER ROLLER BEARING 24028 CCK30/C3W33

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 with two symmetrical rows of rollers and effectively absorbs heavy radial and axial loads. It features a 1:30 tapered bore, a CC design with stamped cages, an extended C3 radial clearance, and an annular groove with three lubrication holes (W33). This bearing type is also self-aligning, meaning it can compensate for misalignment or shaft deflection without compromising performance.

Features:
This open model features a so-called “CC” design that includes two stamped steel window cages, a shoulderless inner ring, and a floating guide ring centered on the inner ring. It features a 1:30 tapered bore that allows for precise mounting on the shaft, either directly or via a locking sleeve. The combination of a seal-less design and an enlarged C3-type internal radial clearance enables the bearing to operate at high speeds. Internal friction is reduced, which limits heat build-up, while the increased tolerance to thermal expansion enhances operational stability during high-speed rotation. Finally, the annular groove and three lubrication holes facilitate efficient maintenance. This self-aligning bearing is ideally suited for applications subject to heavy loads, vibrations, or high rotational speeds.

Maintenance:
This bearing requires regular relubrication to maintain its performance over time. The absence of seals allows for easy visual inspection but requires special attention to cleanliness during maintenance. The three lubrication holes on the outer ring ensure proper lubricant distribution and allow for the removal of contaminants. It is recommended to use a lubricant compatible with operating temperatures, which can reach up to 200 °C depending on the application. If particles or signs of wear are present, thorough cleaning of the housing is recommended before relubrication. This process helps preserve the bearing’s efficiency and minimize the risk of premature failure.

Sealing:
This model is of the open type, meaning it has no built-in seals. This configuration provides direct access to internal components for maintenance but makes it susceptible to contaminants such as dust or moisture. To mitigate this vulnerability, it is equipped with an annular groove and three lubrication holes (W33), which allow for regular relubrication and facilitate the removal of impurities. This helps protect the internal components and extend the bearing’s service life.

Brand Information:
SKF (Svenska KullagerFabriken) is a Swedish multinational group founded in 1907 and a world leader in the field of mechanical bearings. SKF is one of the world’s leading suppliers of bearings, seals, mechatronic components, lubrication systems, and services designed to improve the reliability of rotating equipment and ensure its performance. SKF products can be used anywhere there is motion. They are used in some 40 industrial sectors, including automotive, aerospace, rail, manufacturing, food and beverage, medical, traditional and renewable energy, and agriculture.

Key Benefits:
- Built-in self-alignment to compensate for misalignment and shaft deflection;
- Withstands high radial and axial loads in both directions;
- Deep-drawn steel cages and CC design for high rotational speeds;
- C3 radial clearance for better thermal tolerance and reduced friction;
- Open design facilitating inspection and maintenance operations;
- Tapered bore for secure and precise mounting;
- Integrated lubrication system for extended maintenance intervals.

Applications:
This double-row roller bearing is designed for rotating machinery subjected to heavy loads, such as conveyors, crushers, industrial fans, or agricultural equipment. It is particularly well-suited for environments where operating conditions can cause shaft misalignment. Used in both stationary and mobile installations, it is suitable for both high-speed applications and mechanisms subject to constant vibrations. For long-lasting performance, it must be installed in a clean environment, with lubrication appropriate for the thermal and mechanical conditions of each installation.
