NNU4164-M

The NNU4164-M Cylindrical Roller Bearing stands as a robust solution for industrial applications requiring extreme radial rigidity and high-load capacity. Featuring a double-row design and a solid brass cage (M-type), this bearing is engineered to maintain exceptional stability under fluctuating thermal conditions. With a bore diameter of 320mm and an outer diameter of 540mm, the NNU4164-M excels in managing heavy-duty radial forces while allowing for axial displacement, making it a critical component for large-scale machinery where precision and durability cannot be compromised. The precision-machined rollers ensure uniform load distribution, which significantly reduces friction and extends the operational lifecycle in demanding environments.

Engineered for the rigorous demands of machine tool spindles, rolling mills, and heavy gearboxes, the NNU4164-M double-row cylindrical roller bearing offers unmatched reliability. The integration of a high-strength brass cage provides superior guidance for the rollers, ensuring smooth rotation even at higher limiting speeds. This 218mm wide bearing is designed with a separable structure, simplifying the mounting and dismounting process for maintenance teams. By utilizing high-grade bearing steel and advanced heat treatment processes, the NNU4164-M resists wear and fatigue, providing a cost-effective solution for enterprises looking to minimize downtime and optimize the performance of their heavy-duty mechanical systems.
