NU3164-E-M1A-C3

The NU3164-E-M1A-C3 is a heavy-duty single-row cylindrical roller bearing engineered for demanding industrial environments where high radial loads and high speeds are the standard. This specific model features an "E" reinforced internal design, significantly boosting its load-carrying capacity compared to standard configurations. The M1A solid brass cage, guided by the outer ring, provides exceptional stability and minimizes friction, making it an ideal choice for large-scale machinery such as heavy gearboxes and industrial pumps. Its C3 radial internal clearance is specifically designed to accommodate thermal expansion during continuous operation, ensuring the bearing maintains its structural integrity and precision even under intense heat and high-stress conditions.

As a non-locating NU design bearing, the NU3164-E-M1A-C3 allows for axial displacement of the shaft in both directions, which is critical for preventing internal stress caused by shaft elongation. The outer ring is equipped with two integral ribs, while the inner ring is ribless and completely separable, simplifying the mounting and dismounting process during maintenance. With a massive 320mm bore and a 540mm outside diameter, this bearing is built to support the rotating components of large electric motors and power generation equipment. Its robust construction and P6-grade running accuracy ensure long-term reliability, reducing downtime and optimizing the mechanical efficiency of heavy-duty transmission systems.
