NU 3184 ECMA

Engineered for heavy-duty industrial machinery requiring superior radial load capability, the NU 3184 ECMA single row cylindrical roller bearing features a standard 420 mm bore, 700 mm outer diameter, and 224 mm width. Built with two integral flanges on the outer ring and an unflanged inner ring, the NU 3184 ECMA design accommodates axial displacement of the shaft relative to the housing in both directions while maintaining precise running alignment. Its optimized internal geometry (E-design) delivers exceptional dynamic and static load ratings, complemented by an outer-ring-centered machined brass cage (MA designation) that provides reliable roller guidance, minimized friction, and high operational stability under heavy loads. Furthermore, the fully separable construction of the NU 3184 ECMA allows the inner ring and outer ring assembly to be mounted independently, significantly simplifying installation, dismounting, and routine maintenance in large gearboxes, drives, and heavy machinery.

We provide sea and air freight services for large bearings, and international》shipping services for small bearings.
