The IR38X43X20 is a hardened and ground inner ring designed for use with needle roller bearings without integrated inner rings, such as those in the HK, NK, and NKI series. Its main function is to provide a precise and durable raceway surface when the shaft cannot be heat-treated or ground.
With an inner diameter of 38 mm, outer diameter of 43 mm, and a width of 20 mm, this ring ensures excellent support and uniform load distribution, enhancing the performance and lifespan of the entire system.
