Önbeálló görgőscsapágyak SKF 22205/20 E

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 characterized by its self-aligning capability and its resistance to high radial and axial loads. Thanks to its two symmetrical rows of rollers, its deep-drawn steel cage, and its E-type design, this bearing offers remarkable stability and a long service life. Its open, seal-less design facilitates inspection and maintenance, while ensuring excellent mechanical performance under a variety of operating conditions.

Features:
This SKF self-aligning bearing withstands both high radial loads and axial loads in both directions. Its E-design combines two stamped steel window cages, a shoulderless inner ring, and a floating guide ring, which ensures even force distribution, reduces inertia, and enables higher rotational speeds while maintaining stable operation. The cylindrical bore allows for direct and secure mounting on the shaft. It also features an annular groove and three lubrication holes on the outer ring, facilitating relubrication. Its open design allows for quick inspection, which is ideal for regular monitoring without complex disassembly.

Maintenance:
Regular maintenance is essential to ensure the bearing’s longevity, and visual inspection is facilitated by the absence of seals, which simplifies inspection procedures. Lubrication should be performed at intervals appropriate to operating conditions, particularly in the presence of contaminants. Thanks to its integrated lubrication features, lubricant distribution is uniform, reducing the risk of premature wear. It is recommended to monitor the operating temperature, which can reach up to 200 °C, depending on the lubricant used. If impurities or signs of degradation are detected, a thorough cleaning of the housing and external components is essential before any further lubrication.

Sealing:
This bearing is of the open type, meaning it has no built-in seals. This has the advantage of reducing rolling resistance, promoting smoother rotation and improved efficiency. However, this design requires increased vigilance in dusty or humid environments. The absence of seals makes it more susceptible to particle ingress, which necessitates rigorous maintenance. To compensate, built-in lubrication systems facilitate the removal of contaminants during relubrication.

Brand Information:
SKF, founded in 1907, is a major player in the field of solutions for rotating equipment. Specializing in bearings, seals, and lubrication systems, the Swedish brand is recognized for its technical expertise and innovations that meet the diverse needs of industrial sectors such as automotive, aerospace, energy, and food processing.

Key Benefits:
- Withstands high radial and axial loads in both directions;
- Self-aligning design that compensates for shaft misalignment;
- High-speed operation thanks to low cage inertia;
- Easy maintenance with direct visual inspection;
- Integrated lubrication systems for improved grease distribution;
- Operating temperatures up to 200 °C depending on the lubricant;
- Cylindrical bore for quick installation without additional accessories.

Applications:
This double-row roller bearing is particularly well-suited for industrial environments subject to high mechanical loads. It is used in pulp production equipment, industrial transmission systems, rolling mills in the metallurgical industry, and textile machinery. It is also suitable for conveyors and material-handling equipment, particularly in systems exposed to dynamic loads and speed variations.
