NU252-E-M1-C3

The NU252-E-M1-C3 is a premium-grade, single-row cylindrical roller bearing engineered for demanding industrial environments requiring high radial load capacities. Featuring a 260mm bore, 480mm outside diameter, and 80mm width, this model integrates the reinforced "E" internal design to maximize its dynamic and static load ratings. The M1 machined brass cage provides superior guidance for the rolling elements, ensuring stability and reduced heat generation even during high-speed rotations. As an NU design, the outer ring features two integral ribs while the inner ring is ribless, making it an ideal "floating" bearing that accommodates axial displacement caused by thermal expansion of the shaft.

Built to exact standards, the NU252-E-M1-C3 features a C3 radial internal clearance, which is larger than normal to prevent seizure in high-temperature or heavy-interference fit applications. This specialized clearance allows the bearing to maintain optimal performance under a temperature range of -30°C to +150°C. Its robust construction makes it a reliable choice for heavy-duty machinery, including large electric motors, industrial gearboxes, and centrifugal pumps. By utilizing high-purity steel and precision-ground raceways, this bearing minimizes friction and extends service intervals, significantly reducing downtime in critical infrastructure and manufacturing sectors.
