NU 226 ECP

The NU 226 ECP bearing stands out as a highly efficient choice for machine designs where optimizing power transmission under extreme conditions is crucial. Its core strength lies in its capacity to handle significantly heavy radial loads while maintaining precision at high operating speeds. The defining characteristic of the 'NU' designation is the design of its raceways: the outer ring features two fixed flanges, while the inner ring is completely smooth. This particular setup allows the bearing to serve as an exceptionally effective free-end support. It readily accommodates thermal expansion and contraction within the machine shaft without inducing stress, ensuring the bearing system remains stable and prevents misalignment issues that could lead to premature failure.

Incorporating the advanced 'ECP' architecture, this roller bearing is equipped with an optimized internal geometry and a high-strength, glass fiber-reinforced polyamide cage (P). This cage is lightweight and corrosion-resistant, reducing friction and heat generation, which is vital for achieving extended lubrication intervals and superior performance over long duty cycles. The separable design-the inner and outer rings can be mounted separately-drastically simplifies installation and maintenance, cutting down on machine downtime. The NU 226 ECP, with its robust structure and dimensional precision (130 mm bore, 230 mm OD, 40 mm width), is highly valued in the steel industry, large electric motors, pulp and paper machinery, and mining equipment where consistent, heavy-duty operation is the norm.
