FAG 22317-E1-XL-T41D SPHERICAL ROLLER BEARING

This FAG self-aligning bearing belongs to the family of spherical roller bearings. It is designed to compensate for misalignment and absorb heavy loads. Thanks to its double row of rollers, it withstands both radial and axial forces. This open, seal-less design, featuring a stamped steel cage, is specifically engineered to withstand high-vibration environments.

Features:
This FAG double-row roller bearing stands out for its ability to withstand heavy loads, even under continuous vibration, repeated shocks, or dynamic misalignment. In fact, this T41D version ensures increased stability thanks to precise control of internal clearance, improved resistance to vibration fatigue, and a Durotect® CK coating on the bore. This surface treatment minimizes seizure during installation, provides effective protection against contact corrosion, and is particularly useful for slip fits or in cases of insufficient installation lubrication. It is designed with a cylindrical bore and a lightweight steel cage, ensuring good distribution of dynamic forces. Its E1 design improves mechanical strength by eliminating the central shoulder, thereby optimizing load distribution. The C4 internal radial clearance promotes good thermal performance, reducing overheating during continuous operation. Finally, X-life technology improves surface quality and extends service life, while reducing friction and energy losses.

Maintenance:
This bearing requires regular lubrication, especially in contaminated environments. It features an annular groove and three holes on the outer ring to allow for effective relubrication. It is recommended to use a vibration-resistant grease in small quantities but at frequent intervals. Cleanliness is essential during maintenance operations, particularly during installation or inspection. The permissible temperature range is from –30°C to +200°C, provided a compatible lubricant is used. The X-life version facilitates lubricant circulation, which limits internal heating.

Sealing:
This product features an open design with no integrated seals. It is therefore not protected against dust, liquids, or other contaminants. However, the absence of seals allows for direct visual inspection and easier relubrication, but requires very clean installation and operating conditions. In dirty environments, enhanced maintenance is essential to ensure the bearing’s performance and service life.
