NRT 120 C/G

ngineered for the highest standards of rotational accuracy, the NRT 120 C/G is a super-precision axial-radial cylindrical roller bearing. This specialized component features a unique integrated design with a double-direction axial bearing and a full complement radial roller bearing. The axial section contains two roller and cage assemblies, while the radial section provides high load-carrying capacity. The "C/G" suffix indicates specific design characteristics, often relating to the internal geometry and preload, tailored for exceptional performance in demanding applications. Fixing holes in the outer ring facilitate simple and secure mounting directly to adjacent machine components.

The primary advantage of the NRT 120 C/G is its ability to provide extremely rigid and precise support for combined loads. It is designed to accommodate heavy axial loads in both directions, a high radial load, and significant tilting moments simultaneously. This multi-load capability from a single bearing unit simplifies machine design and assembly. The super-precision manufacturing tolerances ensure very high running accuracy, minimal run-out, and exceptional stiffness, which are critical for achieving superior workpiece quality and process reliability in high-tech machinery.

This type of axial-radial bearing is the preferred choice for applications where ultimate precision is paramount. The NRT 120 C/G is predominantly used in the rotary tables of high-precision machine tools, indexing heads, and various milling and grinding heads. Its robust construction and high rigidity are also ideal for advanced measuring and inspection equipment, radio telescopes, and other high-accuracy positioning systems that demand flawless rotational control and stability under complex loads.
