The NACHI NU204 cylindrical roller bearing features a bore diameter of 20 mm, an outer diameter of 47 mm, and a width of 14 mm, designed for heavy radial load capacity. It has a basic dynamic load rating of 15,400 N and a static load rating of 12,700 N, with a minimum radius (R) of 1 mm. The bearing supports grease lubrication speeds up to 15,000 rpm and oil lubrication speeds up to 18,000 rpm. Its rolling elements are precisely ground and crowned to reduce edge loading and accommodate shaft misalignments, making it easy to mount and dismount in various industrial applications.
