Rulment cu role sferice FAG 23220-E1A-XL-M-C3

Designed for heavy-duty industrial machinery, this FAG spherical roller bearing combines robustness and performance while automatically compensating for misalignment thanks to its specific geometry.

Features:
The E1A design, which lacks a central shoulder but features two lateral retaining shoulders on the inner ring, ensures precise axial guidance and uniform load distribution. Its two rows of rollers optimize the simultaneous handling of radial and axial forces. The one-piece brass cage guarantees excellent mechanical stability under load. The C3 internal radial clearance, slightly larger than the standard, provides better performance at high speeds by reducing friction and heat generation. The lubrication system, featuring three holes and a groove on the outer ring, ensures uniform relubrication and the removal of contaminants. Thanks to X-life technology, contact geometries are optimized, increasing dynamic capacity and service life. The cylindrical bore facilitates direct mounting (with or without shrink fit) on a machined shaft, without additional components.

Maintenance:
The open design requires increased vigilance regarding the operating environment, particularly in the presence of solid or liquid contaminants. The absence of seals facilitates visual inspections but leaves the bearing more exposed to external contaminants. An appropriate maintenance strategy is therefore essential. Recommendations for reliable operation:
- Use high-performance grease or a specific oil depending on load and temperature conditions;
- Ensure regular relubrication, especially in dusty or humid environments;
It is important to systematically check, during each Maintenance:
- the cleanliness of the housing;
- the absence of overheating;
- the presence of abnormal noise;
- the proper alignment of the assembly.

Sealing:
The absence of seals reduces friction losses and simplifies relubrication, but requires rigorous protection against external contaminants. The annular groove and the three lubrication holes ensure uniform distribution of the lubricant and facilitate the removal of impurities.
A clean environment and periodic maintenance are essential to maintaining performance over time.
