SKF SPHERICAL ROLLER BEARING 22348CCK/W33

This spherical roller bearing from SKF features a tapered bore with a ratio of 1:12, enabling precise mounting and efficient load distribution. It offers excellent resistance to high loads and shaft deflections. Thanks to the integrated relubrication feature with a circumferential grease groove and three lubrication holes in the outer ring, easy maintenance and extended service life are ensured. The open design without seals, its robust construction and high speed resistance make this bearing a reliable solution for applications with dynamic loads and varying speeds.

Features:
Equipped with two rows of symmetrical rollers, this self-aligning bearing ensures an even distribution of both radial and axial loads. The open design incorporates two stamped steel sheet cages that are light yet mechanically stable. This construction reduces rolling resistance and allows higher speeds. The tapered bore with a ratio of 1:12 facilitates direct mounting or installation using an adapter sleeve and provides precise internal clearance, optimal load distribution and reduced vibration. The circumferential grease groove with three lubrication holes in the outer ring enables targeted and reliable lubrication. This configuration ensures high operational reliability, even at high speeds and under variable operating conditions.

Maintenance:
Regular maintenance is crucial to preserve the performance and service life of this bearing. The open design allows easy inspection but requires particular cleanliness. It is recommended to relubricate the bearing regularly, especially in environments with dust or moisture. Before each lubrication, the bearing housing should be cleaned thoroughly to keep abrasive particles away. The choice of the correct lubricant is decisive, especially for applications with high temperatures. Operation up to 200 °C is possible provided a suitable lubricant is used.

Sealing:
This model does not have integrated seals and is therefore sensitive to contamination. A clean environment around the installation site is therefore essential. Due to the existing grease groove and lubrication holes, the bearing can be easily relubricated if necessary to flush out dirt particles and thereby extend the bearing's service life. The open construction also facilitates maintenance work.

Brand information:
SKF (Svenska KullagerFabriken) is a Swedish group founded in 1907 and a world-leading supplier in rolling bearing technology. The brand is among the world’s largest manufacturers of bearings, seals, mechatronic components, lubrication systems and services to improve the reliability of rotating equipment. SKF products are used wherever something moves. They are found in numerous industries such as the automotive industry, aerospace, rail transport, mechanical engineering, food processing, medical technology, power generation (conventional and renewable) and agriculture.

Strengths:
• Precise adjustment of internal clearance via tapered bore
• Automatic compensation of shaft misalignment
• High load-carrying capacity for radial and axial loads in both directions
• Operation at high speeds without excessive heating due to open design
• Simple and effective relubrication thanks to special lubrication holes
• Mechanical stability up to 200 °C with a suitable lubricant

Applications:
This bearing is ideal for industrial machinery subjected to high loads and shaft deflections. It is frequently used in conveyor systems, gearboxes and agricultural machinery. It is particularly suitable for equipment where exact alignment is difficult to achieve and variable speeds occur. Due to its robust construction and versatile mounting options, this bearing can be flexibly integrated into a wide range of machine concepts.
