FAG WS22212-E1-XL-2RSR SPHERICAL ROLLER BEARING

This FAG brand spherical roller bearing is designed to provide a robust and reliable solution for demanding industrial applications. Featuring two rows of rollers and a sheet steel cage, it combines self-aligning capability, excellent resistance to heavy loads, and enhanced durability. Its sealed design with contact seals (-2RSR) ensures excellent sealing, while its cylindrical bore facilitates installation. This pre-lubricated model also features an annular groove and three lubrication holes, allowing for efficient maintenance without disassembly.

Features:
The symmetrical double-row roller structure ensures even distribution of radial and axial loads, while maintaining excellent dynamic stability. The NBR contact seal system on both sides provides continuous protection against external contaminants. Its deep-drawn steel sheet cage reduces inertia and enables smooth operation at moderate speeds. The E1 design, without a central shoulder, optimizes load distribution across the raceways. The increased width provides a larger contact area to improve stability under load and extend the bearing’s service life.

Maintenance:
This bearing is supplied pre-lubricated with high-performance Arcanol LOAD400 grease. It must not be washed before installation. When relubrication is necessary, slowly inject the same grease through the lubrication ports, preferably while the bearing is rotating to avoid damaging the seals. It is important not to overfill the bearing with grease. Rigorous maintenance includes cleaning the lubrication points before each service and regularly inspecting operating parameters (noise, temperature, vibrations).

Sealing:
The two NBR sliding seals provide reliable protection against moisture, dust, and liquid splashes. They are reinforced with a steel sheet reinforcement, ensuring excellent mechanical strength. Although the seals create slight friction, they help reduce low-frequency vibrations. This sealed design improves durability by effectively protecting internal components while allowing for relubrication during operation via the annular groove and lubrication holes.
