Rulment cu bile SNR 6009ZZC3, Diametrul exterior: 75 mm | Lățime: 16 mm | Diametrul interior: 45 mm

This SNR deep groove ball bearing has been designed for smooth and long-lasting operation, even at high speeds. Equipped with two non-contact metal shields, it provides reliable protection against particles while maintaining low friction. It is particularly suited for applications in moderately contaminated environments where dynamic performance and thermal stability are critical.

Features:
The bearing has a stamped steel cage and two non-contact metal shields that form a labyrinth sealing system. This effectively reduces the ingress of medium-sized contaminants. The outer ring groove accommodates the steel shields, while the inner ring features a V-groove that facilitates the ejection of dirt. This design minimizes lubricant losses and improves grease retention inside the bearing. The internal radial clearance of class C3 allows better compensation for thermal expansions at high speeds while ensuring stable alignment of the rolling elements. The bearing is factory-lubricated with a high-performance grease for long-term use, making it ideal for continuous-duty dynamic applications.

Maintenance:
This model is factory-lubricated and requires no relubrication under normal operating conditions. The metal shields reliably protect the grease from external influences while reducing internal loss. In warm, humid, or dusty environments, regular inspections can be advisable to ensure trouble-free operation without excessive wear.

Sealing:
The two deep-drawn metal cover discs provide an effective barrier against dust and mechanical contaminants. The non-contact sealing system preserves high speed capability while reducing lubricant evaporation. It is optimally suited for areas with moderate contamination, but is not intended as full protection against moisture or aggressive chemicals.
