Product Overview: The NU 420 Cylindrical Roller Bearing
The NU 420 is a high-performance cylindrical roller bearing with dimensions of 100x215x47mm, engineered to handle heavy radial loads at high speeds. As part of our extensive NU 400 Series, this bearing is a crucial component in demanding industrial applications. The 'NU' designation signifies its unique design, featuring two integral flanges on the outer ring and a smooth, flangeless inner ring. This configuration allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for accommodating thermal expansion and minor shaft misalignments.
Manufactured to precise industry standards, the NU 420 offers exceptional reliability and a long service life. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation and maintenance procedures.
