NU 3168 ECMA

The NU 3168 ECMA is a high-performance single row cylindrical roller bearing designed to handle heavy radial loads in demanding industrial environments. This specific configuration features a flangeless inner ring and a double-flanged outer ring, allowing for axial displacement of the shaft in both directions within the bearing. This "floating" capability makes it an ideal solution for applications where thermal expansion of the shaft is expected, ensuring smooth operation without inducing internal stress.

Engineered with a robust machined brass cage (MA) that is outer-ring centered, the NU 3168 ECMA offers superior stability and reduced friction at high rotational speeds. The optimized internal geometry and precision-ground rollers promote even load distribution and enhanced lubricant film formation, significantly extending service life. Whether utilized in large electric motors, gearboxes, or heavy machinery, this bearing provides the high radial stiffness and durability required for critical mechanical systems.
