NU 313 ECML

The NU 313 ECML stands as a high-performance single row cylindrical roller bearing designed to excel in demanding industrial environments where high radial loads and substantial speeds are the norm. This specific model features a 65mm bore, 140mm outside diameter, and a 33mm width, adhering to metric precision standards. Its "NU" configuration signifies a design with two integral flanges on the outer ring and a smooth, flangeless inner ring. This critical design choice allows for significant axial displacement of the shaft relative to the housing in both directions, making it an ideal solution for compensating for thermal expansion in rotating machinery.

What distinguishes the NU 313 ECML from standard variants is its optimized internal geometry (EC) and the inclusion of a robust machined brass cage (ML). The brass cage is particularly valued for its superior strength and heat dissipation properties compared to synthetic alternatives, ensuring reliable operation in high-vibration or heavy-duty applications like gearboxes, electric motors, and heavy industrial pumps. With a basic dynamic load rating of approximately 212 kN, this bearing offers a low-friction, long-service-life solution for engineers seeking to minimize downtime and maximize the efficiency of their high-speed rotational equipment.
