NU 209 ECML

The NU 209 ECML is a high-performance single-row cylindrical roller bearing engineered for applications demanding superior radial load capacity and high-speed precision. Featuring a 45mm bore, 85mm outside diameter, and 19mm width, this specific NU-design incorporates two integral flanges on the outer ring and a flange-less inner ring, allowing for significant axial displacement in both directions. The "EC" designation signifies an optimized internal geometry for increased load ratings, while the ML suffix denotes a robust, machined brass cage guided by the rolling elements. This combination ensures reduced friction and minimal heat generation, even when operating at limiting speeds of up to 15,000 r/min.

Designed for long-term reliability in harsh industrial environments, the NU 209 ECML excels in power generation, manufacturing machinery, and automotive transmissions. Its separable design is a critical advantage, simplifying mounting and dismounting procedures by allowing the bearing components to be interchanged easily. With a dynamic load rating of approximately 69.5 kN and a static load rating of 64 kN, this bearing provides exceptional fatigue resistance. Whether used in high-speed electric motors or complex gearboxes, the machined brass cage provides the necessary stability to handle vibrations and centrifugal forces that would typically compromise standard pressed steel alternatives.
