SKF 22211 E/C3W64 SRB SOLID OIL

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.

Featuring Solid Oil technology, this SKF roller bearing ensures permanent, lifetime lubrication. It effectively compensates for misalignment and shaft deflection thanks to its double-row roller design and self-aligning capability.

Features:
This self-aligning roller bearing features an advanced E-design with stamped steel window cages, promoting better load distribution. Its cylindrical bore allows for quick and easy installation, ideal for reducing machining costs. The C3 internal radial clearance provides better tolerance to thermal expansion and reduces internal stresses, ensuring rotational stability at high speeds. This bearing is seal-less, thereby minimizing friction to achieve higher speeds. Solid Oil technology ensures effective lubrication, even in humid environments, reducing wear and extending service life.

Maintenance:
No maintenance is required throughout the bearing’s service life. Thanks to the Solid Oil lubricant, the system remains constantly lubricated without the need for relubrication. This oil-saturated polymer material gradually releases the necessary oil while preventing the penetration of moisture and solid particles. This even eliminates the risk of grease kneading. To maintain performance, however, it is recommended to limit exposure to abrasive contaminants.

Sealing:
This model is open, with no seals. Nevertheless, Solid Oil technology acts as a physical barrier against the entry of contaminants. This system fills virtually all of the bearing’s free space, effectively limiting the migration of liquids or particles. It is therefore particularly well-suited for humid environments or those requiring frequent washing, where traditional bearings would be vulnerable to corrosion or grease loss.

Brand Information:
SKF is a Swedish company founded in 1907 and a global leader in bearing and sealing solutions. With a presence in over 130 countries and 17,000 distributors, the brand focuses on technological innovation, reliability, and sustainability. SKF invests heavily in research to offer high-performance products tailored to modern industrial requirements.

Key Benefits:
- Effective self-alignment, even in the event of shaft deflection or misalignment.
- Permanent Solid Oil lubrication: zero maintenance, high reliability.
- Withstands continuous temperatures from -50 °C to 85 °C, ideal for extreme conditions.
- Reduced wear and extended service life thanks to constant micro-lubrication.
- Suitable for high rotational speeds with minimal heat generation.
- Quick installation without the need for additional accessories.

Applications:
This bearing is particularly recommended for environments exposed to moisture, cleaning agents, or solid contaminants. It is ideally suited for sectors such as marine, food processing, paper manufacturing, industrial transmissions, and textile machinery. Its corrosion resistance and lack of relubrication requirements make it an ideal solution for hard-to-reach installations or those subject to maintenance constraints.
