Sfæriske rullelejer FAG 23940-S-MB

The FAG brand spherical roller bearing stands out for its robustness and exceptional self-aligning capability. Featuring two symmetrical rows of rollers, it is designed to withstand very high radial loads and axial forces in both directions. This product features two solid brass cages, a cylindrical bore, and an integrated relubrication system. Its open, seal-less design optimizes rotational speed and facilitates maintenance, offering a high-performance solution for demanding industrial applications.

Features:
Designed with a structure featuring a rigid central shoulder on the inner ring, this double-row roller bearing provides enhanced axial guidance and optimal load distribution. The solid brass cages ensure high mechanical stability, excellent resistance to dynamic loads, and thermal resistance up to +200°C. The open design ensures low rolling resistance, allowing sustained rotational speeds even under harsh conditions. The standard radial clearance provides a good balance between rigidity and the ability to accommodate thermal expansion, thereby preventing excessive heating. This bearing is ideally suited for applications requiring robustness, high speed, and vibration stability.

Maintenance:
The bearing is vulnerable to contaminants due to its lack of seals. It features an annular groove and three lubrication holes on the outer ring, ensuring even lubricant distribution and the removal of impurities. Regular relubrication is recommended, particularly in dusty environments. Strict cleanliness is essential during maintenance to preserve the product’s performance. Thorough cleaning of the housing and components is crucial in the event of contamination or premature wear.

Sealing:
With its open design, this self-aligning roller bearing remains exposed to dust and moisture. However, the presence of relubrication features improves dynamic protection against contaminants. This design also facilitates visual inspection and makes maintenance operations simpler and faster. A clean environment or the use of external protection systems is recommended to optimize the bearing’s service life.
