Deep groove ball bearing SNR 6316ZZC3, Outer diameter: 170 mm | Width: 39 mm | Inner diameter: 80 mm

This SNR deep groove ball bearing was 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 suitable for applications in moderately contaminated environments where dynamic performance and thermal stability are critical.

Features:
The bearing features a stamped steel sheet 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 metal shield plates, while the inner ring is equipped with a V-groove that facilitates the expulsion of debris. This construction minimizes lubricant loss and improves grease retention inside the bearing. The internal radial clearance of class C3 allows better compensation for thermal expansion at high speeds while ensuring stable alignment of the rolling elements. The bearing is factory-lubricated with a high-performance long-life grease, making it ideal for dynamic, continuous-operation applications.

Maintenance:
This model is factory-lubricated and does not require re-lubrication under normal operating conditions. The metal shields reliably protect the grease from external influences while also reducing internal loss. In warm, humid, or dust-laden environments, regular inspection may 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 well suited for applications with moderate contamination, but is not designed as complete protection against moisture or aggressive chemicals.
