NU 226 ECML

he NU 226 ECML is a precision-engineered radial bearing designed to excel in heavy-duty rotating equipment. Measuring 130x230x40 mm, this model utilizes the EC-geometry upgrade, which refines the roller-to-raceway interface to minimize edge stresses and optimize lubricant film formation. Because the inner ring lacks flanges (NU type), the bearing functions as a non-locating unit, seamlessly permitting the shaft to shift axially relative to the housing. This capability is vital for preventing internal preload caused by linear thermal growth during continuous high-speed operation, ensuring the mechanical integrity of the entire drive train.

Durability in harsh conditions is driven by the integration of the ML-series machined brass cage. This window-type, roller-centered retainer is significantly more resilient than standard metal stampings, providing the structural stiffness required to withstand centrifugal forces and intense vibrations. The separable architecture of the NU 226 ECML facilitates effortless installation and precise internal clearance adjustments during assembly. With a static load capacity of 455 kN and a refined internal finish, this bearing is a preferred choice for high-torque industrial gearboxes and large-scale power generators where downtime is not an option.
