NU2268-E-M1A

The NU2268-E-M1A is a single-row cylindrical roller bearing designed for applications with high radial loads and speeds. The "NU" designation means the outer ring has two fixed ribs while the inner ring is raceway-only, without ribs. This separable design simplifies mounting and dismounting. This bearing's "E" suffix indicates an optimized internal geometry with a larger number of rollers, which significantly increases its dynamic load-carrying capacity. The bearing features a solid brass cage ("M1A") that is guided by the outer ring, providing excellent durability and stable operation, even under tough conditions. Its design makes the NU2268-E-M1A a common choice for use as a non-locating, or "floating," bearing in machinery where thermal expansion of the shaft is a factor.

This cylindrical roller bearing provides a number of key benefits for industrial applications. Its high load capacity and rigidity make it suitable for heavy-duty machinery like gearboxes, pumps, and large electric motors. The separable design allows for the inner and outer rings to be mounted independently, which simplifies the assembly process. The roller-and-cage assembly is highly durable, enabling the bearing to handle high rotational speeds with less friction and heat generation compared to full-complement bearings. As a non-locating bearing, the NU2268-E-M1A can accommodate axial displacement between the shaft and the housing, which is crucial for preventing stress and premature wear in systems where components expand or contract due to temperature changes. This combination of features results in improved machine performance and a longer service life.
