Product Overview: The NJ 312 Cylindrical Roller Bearing
The NJ 312 bearing is a premium single-row cylindrical roller bearing, renowned for its exceptional radial load capacity and high-speed performance. With a bore diameter of 60 mm, an outer diameter of 130 mm, and a thickness of 31 mm, this bearing is a critical component in demanding industrial applications. Belonging to the NJ 300 Series, it features a removable inner ring (or outer ring, depending on design), allowing for easier mounting and dismounting. The NJ type bearing has two integral flanges on the outer ring and one integral flange on the inner ring, which enables it to accommodate axial displacement in one direction, while still providing robust radial support. Our company ensures that all NJ 312 bearings meet stringent industry standards, offering superior durability and operational efficiency in various machinery.
As a leading provider of industrial bearings and mechanical parts, we supply NJ 312 bearings that are engineered for reliability and long service life, even under harsh operating conditions. This design is particularly suitable for applications where high radial loads are present and precise shaft guidance is required. Explore our comprehensive selection of cylindrical roller bearings to find the ideal solution for your specific industrial needs.
