NU248-E-M1-C3

The NU248-E-M1-C3 Cylindrical Roller Bearing is engineered to handle extremely high radial loads and operate efficiently under demanding conditions. As a single-row bearing with the NU design, it features two rigid ribs on the outer ring but none on the inner ring. This configuration is specifically designed to function as a floating bearing, allowing for axial displacement between the shaft and the housing. This essential capability makes the NU248-E-M1-C3 ideal for applications where thermal expansion or contraction of the shaft material is a concern. With a large bore diameter of 240 mm, an outer diameter of 440 mm, and a width of 72 mm, this robust component weighs approximately 51.8 kg and is a heavy-duty solution for industrial machinery.

The performance characteristics of the NU248-E-M1-C3 are denoted by its suffixes. The 'E' designation signifies an Increased Load Capacity design, offering superior dynamic and static load ratings for longer service life. Its internal components feature a durable M1 two-piece machined brass cage, which is roller-guided for reliable high-speed operation up to a limiting speed of 2,320 r/min. Furthermore, the C3 radial internal clearance is slightly greater than normal, which is crucial for high-temperature applications and accommodates a faster running speed without generating excessive heat. Choose the NU248-E-M1-C3 bearing for high-rigidity applications requiring excellent radial load support and compensation for axial movement.
