A full complement of roller bearings without an outer ring are bearings that use cylinders as rolling elements instead of the balls in a ball bearing. This way, the rollers have a larger (linear) contact area with the outer ring and distribute the load over a wider surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double row cylindrical roller bearings have high radial stiffness and are mainly used in precision machine tools. Many cylindrical roller bearings do not have ribs on the inner or outer rings, so the rings can move axially relative to each other and can be used as free end bearings. Usually pressed steel (with or without tin or fins) or machined brass cages are used, but sometimes moulded polyamide cages are also available depending on the application. Cylindrical roller bearings are also available with full complement roller cages without cages. This allows for higher loads at the expense of speed. The outer ring of single row cylindrical roller bearings also has snap ring grooves. This design simplifies the bearing joint when the bearing is positioned into the housing with a snap ring. For single row bearings there are different types, designated NU, NJ, NUP, N, NF, and for double row bearings there are NNU, NN, depending on the design of the side ribs or their absence. A cupless full complement of roller bearings with cages are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. The outer ring has rigid ribs or no ribs on both sides, and the inner ring has one or two rigid ribs or is designed without ribs. The cage prevents the cylindrical rollers from contacting each other during rolling. 'Classic' cylindrical roller bearings have a very high radial load carrying capacity and high rigidity. In addition to bearing higher radial loads, cylindrical roller bearings can also bear axial loads if used as semi-locating or locating bearings. Radial loads are transmitted through the raceways, while axial loads are transmitted through the rolling element faces and ribs, which of course limit the axial load. Full-roller bearings without an outer ring can accommodate the thermal expansion of the shaft in the bearing. Toroidal roller bearings can now be added to this list. The inner and outer rings of the bearing can be displaced by 10% relative to the bearing width. The allowable axial displacement can be extended in one direction by installing the bearings so that one ring begins to displace relative to the other. In contrast to cylindrical and needle roller bearings, which require precise shaft alignment, this is not required for toroidal roller bearings, which can also handle shaft deflection under load. In many cases, at least one of the major dimensions of the bearing, usually the bore, is predetermined by the mechanical design. Small diameter shafts usually choose deep groove ball bearings, while large diameter shafts can consider using cylindrical roller bearings, spherical roller bearings and full complement roller bearings without outer ring. If radial space is limited, bearings with a small cross-sectional height must be selected, such as needle roller assemblies, some series of deep groove bearings and spherical roller bearings. Where axial space is limited and particularly narrow bearings are required, some deep groove ball and cylindrical roller bearing families are available.
