The NU311MYC3 cylindrical roller bearing features a 55 mm bore diameter, 120 mm outer diameter, and 29 mm width, constructed with a steel alloy and a machined brass cage for durability and precision. This single-row bearing has two flanges on the outer ring and none on the inner ring, allowing axial displacement and supporting high radial loads with a dynamic load capacity around 110,000 N. Designed for high rigidity and speed, it offers increased internal clearance (C3) for thermal expansion and reduced friction. Its robust construction suits applications in gearboxes, pumps, compressors, and electric motors requiring reliable performance and long service life.
