NU 311 ECP

Engineered for applications requiring robust radial support, the NU 311 ECP features a precision-ground assembly with a 55mm inner diameter and 120mm outer diameter. As a premium single-row cylindrical roller bearing, its NU-type construction utilizes two fixed ribs on the outer race and a smooth, ribless inner ring. This specific architecture is essential for floating bearing arrangements, as it provides the necessary clearance for longitudinal shaft expansion without inducing internal axial stress. By facilitating smooth linear movement within the bearing itself, it ensures operational stability even during significant temperature fluctuations.

The "ECP" designation highlights a specialized design optimized for increased load-carrying capacity and superior lubrication flow. This model is equipped with a window-type cage made of glass-fiber reinforced Polyamide 66, which offers a superior strength-to-weight ratio compared to steel. This lightweight polymer cage minimizes centrifugal forces and friction, allowing for a limiting speed of up to 7,000 r/min. Capable of sustaining a dynamic load of 156 kN, the NU 311 ECP is a staple in high-speed industrial machinery, including heavy-duty electric motors and centrifugal pumps, where noise reduction and thermal efficiency are critical.
