Product Overview: The NU 2209 Cylindrical Roller Bearing
The NU 2209 is a single-row cylindrical roller bearing engineered to handle high radial loads at high speeds. With principal dimensions of 45x85x23mm (Bore x Outer Diameter x Thickness), this bearing is a key component in a wide range of industrial machinery. As part of our NU 2200 Series, the NU 2209 features a separable design where the inner ring is free, allowing it to be mounted independently from the outer ring and roller assembly. This characteristic simplifies installation and maintenance procedures. The bearing's design permits axial displacement of the shaft relative to the housing in both directions, making it ideal for accommodating thermal expansion.
