SRV.NU409

The SRV.NU409 stands out as a high-performance single-row cylindrical roller bearing, engineered to handle significant radial loads while maintaining precision at high rotational speeds. Featuring a 45mm bore, 120mm outside diameter, and 29mm width, this unit is designed with a separable structure where the inner ring can be removed from the outer ring assembly. This "NU" type configuration-characterized by two integral flanges on the outer ring and a smooth, flangeless inner ring-not only simplifies mounting and dismounting during maintenance but also allows for axial displacement of the shaft within the housing. It is a go-to choice for engineers looking to compensate for thermal expansion in heavy-duty industrial environments.

Built for durability, the SRV.NU409 often utilizes a robust pressed steel or machined brass cage to ensure optimal roller guidance and even lubricant distribution. This reduces internal friction and heat buildup, which is critical for extending the service life of gearboxes, electric motors, and pumps operating under continuous duty cycles. With its high dynamic load rating and optimized raceway geometry, this bearing minimizes vibration and noise, making it an essential component for precision-driven machinery where reliability and stability are non-negotiable. Whether you are replacing a worn-out component or integrating it into a new mechanical design, the NU409 series offers the rigidity and high-speed tolerance required for modern industrial standards.
