FAG 21311-E1-XL-TVPB-C3 SPHERICAL ROLLER BEARING 190002190030

Thanks to its self-aligning design and polyamide cage, this FAG spherical roller bearing ensures smooth and quiet operation for heavy-duty applications. This spherical roller bearing is ideal for applications requiring reliability, durability, and high performance, even at high speeds.

Features:
This spherical roller bearing is designed with two symmetrical rows of rollers that provide excellent distribution of radial and axial loads. Its optimized internal geometry, without a central shoulder, improves dynamic load capacity. The reinforced polyamide cage, guided by the inner ring, ensures proper guidance of the rolling elements while minimizing friction. The increased internal radial clearance (C3) better compensates for thermal expansion at high speeds. Its open design allows for high rotational speeds while maintaining good stability. This bearing withstands temperatures ranging from –30°C to +120°C continuously, and even up to +150°C for short periods (risk of cage softening) when used with a suitable lubricant. Thanks to the X-life technology developed by Schaeffler, this bearing features a superior internal finish, thereby increasing its service life, load capacity, and smoothness of operation.

Maintenance:
This self-aligning roller bearing does not contain any factory-applied lubricant. It therefore requires lubrication appropriate for its operating environment. Relubrication is facilitated by an annular groove and three machined holes in the outer ring. This allows for even distribution of the lubricant and efficient removal of contaminants. Regular maintenance is recommended, particularly in dusty or humid environments. To ensure proper performance, it is essential to thoroughly clean the housing before performing any maintenance.

Sealing:
This model is open and has no built-in seals. This facilitates visual inspections and maintenance operations but makes it more vulnerable to external contaminants. In case of exposure to dust or moisture, it is crucial to ensure a clean environment or effective external protection. The absence of seals also means lower mechanical resistance, which promotes smoother rotation and higher speeds. However, it is necessary to regularly monitor the condition of the lubricant to prevent premature wear.
