Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs.
FAG high precision cylindrical roller bearings are used where very high accuracy is required in machine tools and printing machinery. They are ideal as non-locating bearings since they allow unconstrained compensation of changes in length during rotational movement between the rollers and raceways. Due to their high accuracy with high radial rigidity, cylindrical roller bearings in a high precision variant are also used – in addition to their application as Non-locating bearings.
