Sfæriske rullelejer FAG 21309-E1-XL-C3

Equipped with X-life technology developed by FAG, this spherical roller bearing ensures extended service life, reduced friction, and optimized performance.

Features:
- Two rows of symmetrical rollers: ensure even load distribution and good operational stability.
- Deep-drawn steel sheet cage: lightweight and durable, it guarantees good performance under dynamic loads and enables smooth operation at high speeds.
- Open design without a central shoulder: optimizes the internal geometry for increased load capacity.
- Cylindrical bore: facilitates direct mounting on the shaft, without the need for an intermediate ring or sleeve.
- X-life technology: improves the quality of contact surfaces, reduces friction, and significantly extends bearing life by improving lubricant circulation.
- Increased internal radial clearance (C3): accommodates thermal expansion and reduces the risk of overheating during continuous operation.
- Suitable for high speeds: thanks to its optimized design and the precision finish of the rolling elements.
- Effective performance under combined loads: withstands both high radial loads and axial loads in both directions.

Maintenance:
Lubrication is essential to ensure the longevity of this self-aligning ball bearing. It is equipped with an annular groove and three lubrication holes in the outer ring, allowing for effective relubrication without disassembly. This configuration promotes uniform lubricant distribution and facilitates the removal of contaminants. Regular lubrication is recommended, especially in contaminated environments. The permissible temperature range is from –30 °C to +200 °C, provided a suitable lubricant is used.

Sealing:
The absence of seals makes this spherical roller bearing vulnerable to external contaminants, such as dust, moisture, or solid particles. It is therefore essential to ensure effective external protection in dirty or exposed environments. Thorough and frequent lubrication is necessary to prevent the intrusion of contaminants and maintain performance over time.
On the other hand, this open design facilitates visual inspection and simplifies maintenance. The absence of seals reduces rolling resistance, allowing operation at higher speeds. The open configuration also allows for direct and effective relubrication during operation.
