NTN (Nippon Thompson Co., Ltd.) and NR (which commonly stands for "nozzle ring" in certain engineering contexts). More details:
- NTN (Nippon Thompson Co., Ltd.):
NTN is a Japanese company that produces bearings, constant velocity joints, and other precision industrial equipment. Bearings are mechanical components that reduce friction between moving parts and facilitate the rotation of various components in machinery. NTN is known for manufacturing a wide range of high-quality bearings used in automotive, industrial, and aerospace applications. - NR (Nozzle Ring):
NR typically stands for "nozzle ring" in various engineering applications, particularly in the context of turbines or compressors. The nozzle ring is a component in a turbine or compressor that directs the flow of a fluid (such as air or gas). In the case of a gas turbine, for example, the nozzle ring is part of the turbine stage and helps control the speed and direction of the hot gases that drive the turbine blades.The nozzle ring is often adjustable to optimize the performance of the turbine or compressor under different operating conditions. By changing the position or angle of the nozzle ring, engineers can control the flow of the working fluid and, consequently, the efficiency and power output of the turbine or compressor.
