Design and structure

Cylindrical roller bearing is a kind of precision bearing, mainly used in machine tools and other equipment to provide radial support. The bearing consists of an outer ring with no rims, an inner ring with three rims, and a cylindrical roller and solid brass cage assembly to optimize the setting of radial internal clearance. In addition, there are single -, double - and four-column designs, as well as different series such as NU, NJ, NUP, N, NF, etc.
