Cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.and they are different types,for example: designed as NU, NJ, NUP, N, NF(for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).
