Rulment cu role sferice FAG 21307-E1-XL-K-TVPB

Spherical roller bearings are designed to withstand heavy loads in environments subject to misalignment or shaft deflection. Widely used in industrial equipment such as compressors and gearboxes, they offer robustness, smooth operation, and a long service life.

Features:
This FAG spherical roller bearing features Schaeffler’s X-life technology. It is characterized by improved surface finishes, which significantly increase its service life and performance, while ensuring high resistance to radial and axial loads, even in the event of misalignment. It features a reinforced polyamide cage, guided by the inner ring, which enables quiet, low-friction operation and supports high rotational speeds. The tapered bore mounting allows for precise adjustment of the internal clearance to achieve optimal tightening or preload. Its E1 design, without a central shoulder, significantly improves dynamic load capacity.

Maintenance:
This self-aligning ball bearing requires lubrication suitable for the operating environment, using either grease or oil. The absence of a built-in relubrication system necessitates more rigorous maintenance. The condition of the lubricant should be checked regularly, and impeccable cleanliness must be ensured during maintenance operations. During continuous operation, the temperature must not exceed 120°C to preserve the integrity of the polyamide cage.

Sealing:
This spherical roller bearing is designed without seals. Its open design promotes efficient cooling, allows for free circulation of the lubricant, and helps reduce internal friction. However, this makes it more susceptible to external contaminants such as abrasive dust, moisture, corrosive liquids, or abrasive particles. On the other hand, this configuration facilitates relubrication and visual inspection of the components. It is therefore best to use it in clean environments or in protected systems, paying particular attention to the quality of the lubrication and preventive maintenance.
