NU Series Cylindrical Roller Bearings

NU-type cylindrical roller bearings feature a double flange on the inner ring and no flange on the outer ring. They are primarily designed to withstand purely radial loads, allowing for bidirectional axial movement between the shaft and the housing, thereby effectively compensating for thermal expansion and contraction of the shaft.

With high load-carrying capacity, high rigidity, and good speed adaptability, these bearings have a separable design that facilitates easy installation and removal. They are commonly used in transmission components requiring free expansion and contraction, such as electric motors, fans, machine tools, and gearboxes.
