NU 322 ECML

The NU 322 ECML stands as a robust solution for rotating equipment requiring high radial stiffness and precision. Distinguished by its separable design, this single row cylindrical roller bearing features a flangeless inner ring, allowing the shaft to move axially without restriction. This "non-locating" capability is vital for preventing internal stress caused by shaft elongation in high-temperature operations. By integrating the EC internal geometry, the contact area between the rollers and raceways is optimized to minimize friction, which significantly extends the service life and enhances the reliability of heavy-duty drivetrains and industrial pumps.

Engineered for the most demanding environments, the NU 322 ECML incorporates a machined brass cage (ML) that is roller-centered for maximum stability. This heavy-duty brass construction is far superior to standard polymers, offering enhanced vibration dampening and the ability to withstand the chemical additives found in synthetic lubricants. With a substantial 110mm bore diameter and a dynamic load rating capable of handling massive radial forces, this bearing is frequently specified for large-scale electric motors and traction applications. Its ability to maintain a cool operating temperature even at high speeds ensures that maintenance intervals are prolonged and unexpected downtime is minimized.
