SKF SPHER ROLLER BEARING 23236 CCK/W33

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

This SKF bearing features a spherical roller design with a 1:12 tapered bore, which enables precise mounting and efficient load distribution. It delivers excellent performance under heavy loads and in the presence of shaft deflection. Thanks to its integrated relubrication system—which includes an annular groove and three holes on the outer ring—it ensures simplified maintenance and extended service life. Its seal-less design, robustness, and compatibility with high speeds make it a reliable solution for applications subject to dynamic loads and speed variations.

Features:
Equipped with two symmetrical rows of rollers, this self-aligning bearing provides balanced distribution of both radial and axial loads. Its open design incorporates two lightweight yet strong stamped steel cages, ensuring excellent mechanical stability. This open configuration has the advantage of reducing rolling resistance and allowing for higher speeds. The 1:12 tapered bore facilitates direct mounting or mounting via a sleeve, ensuring precise adjustment of internal clearance, excellent load distribution, and reduced vibration. An annular groove accompanied by three holes on the outer ring allows for optimal lubrication. This configuration ensures high reliability under a variety of operating conditions, even at high speeds.

Maintenance:
Regular maintenance is essential to preserve the longevity and performance of this bearing. The open design allows for easy inspection but requires special attention to cleanliness. Periodic relubrication is recommended, especially in environments exposed to dust or moisture. Before each relubrication, the housing should be thoroughly cleaned to prevent the introduction of abrasive particles. The choice of lubricant is critical, particularly for high-temperature applications. The product can operate at temperatures up to 200 °C, provided a suitable lubricant is used.

Sealing:
This model does not have built-in seals, making it vulnerable to contaminants. It is therefore essential to maintain a clean environment around the mounting location. Thanks to its annular groove and lubrication holes, it is easy to relubricate the bearing to flush out impurities and extend the component’s service life. This open design also facilitates maintenance operations.

Brand Information:
SKF (Svenska Kullager-Fabriken) 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:
- Ensures a precise internal clearance fit with its tapered bore;
- Automatically compensates for shaft misalignment;
- Withstands high radial and axial loads in both directions;
- Operates at high speeds without excessive overheating due to the absence of seals;
- Allows for simple and effective lubrication thanks to dedicated ports;
- Maintains its mechanical properties up to 200 °C with a suitable lubricant.

Applications:
This type of bearing is ideal for industrial equipment subjected to heavy loads and shaft deflections. It is commonly found in electric motors, conveyors, pumps, gearboxes, and agricultural equipment. It is particularly well-suited for machines where precise alignment is difficult to maintain and where rotational speeds may vary. Thanks to its robustness and installation flexibility, it integrates easily into many mechanical configurations.
