SKF 22211 EK/C4 SPHERICAL ROLLER BEARING

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.

Thanks to its self-aligning capability and robust structure, this self-aligning ball bearing ensures excellent resistance to high loads, whether radial or axial. Its reinforced design ensures exceptional stability even in the event of shaft deflection or misalignment.

Features:
This bearing features two rows of rollers, giving it very good load-carrying capacity. It is equipped with a stamped steel cage, which reduces inertia for better performance at high speeds. The C4 internal radial clearance improves tolerance to temperature variations, vibrations, and high speeds, ensuring smooth rotation even at high temperatures (up to 200 °C). Its 1:12 tapered bore facilitates quick mounting on a shaft or sleeve, reducing vibrations and ensuring a secure fit. Its open design, combined with an optimized E-structure, makes it particularly effective for heavy-duty applications where reliability and performance are essential.

Maintenance:
This bearing requires special attention regarding lubrication, as it is shipped without grease. An annular groove and three holes on the outer ring allow for direct and effective lubrication during operation. A high-performance lubricant suitable for high loads and operating temperatures is recommended. Regular visual inspection is facilitated by the open design. It is advisable to thoroughly clean the housings during maintenance. In heavy-duty applications, frequent relubrication helps extend its service life and maintain its performance.

Sealing:
This model is of the open type, without seals. This configuration has the advantage of reducing internal friction, thereby enabling high rotational speeds while minimizing losses. However, it makes the bearing more vulnerable to contaminants such as dust or moisture. To minimize these risks, it is important to protect the mounting area and relubricate regularly. This design is ideally suited for clean environments or systems that are already protected.
