NU428-M1-C3

The NU428-M1-C3 cylindrical roller bearing stands as a robust solution for high-load industrial environments, featuring a precision-engineered 140mm bore and a substantial 360mm outside diameter. As a single-row non-locating bearing, its NU design incorporates two fixed ribs on the outer ring and a smooth, ribless inner ring, allowing for seamless axial displacement of the shaft relative to the housing. This makes it an ideal choice for managing thermal expansion in heavy machinery. The integration of a solid brass cage (M1), which is roller-guided, ensures superior stability and reduced friction even under extreme centrifugal forces, significantly extending the service life of the component compared to standard pressed steel alternatives.

Designed for high-speed reliability, the NU428-M1-C3 is manufactured with a C3 radial internal clearance, providing the necessary room for expansion during intense heat buildup and ensuring smooth rotation at limiting speeds up to 2,950 rpm. With a massive static load rating of 1,110,000 N, this bearing is purpose-built for the most demanding applications, including large electric motors, industrial gearboxes, and heavy-duty pumps. Its separable design simplifies the mounting and dismounting process, allowing for independent installation of the inner and outer rings. Whether utilized in mining equipment or paper mill machinery, the FAG-standard precision of the NU428-M1-C3 delivers the rigidity and radial load capacity required for continuous, maintenance-free operation.
