McGILL comprise plastic or metal axial cages with integrated needle rollers and have a very small axial section height. They can support high axial forces in one direction. Radial loads must be supported by separate means. Axial needle roller and cage assemblies require hardened and ground axial running surfaces for use as raceways.
McGILL are punched, through hardened and polished and can be used as shaft or housing locating washers. These washers are suitable if the adjacent machine part is unhardened but is sufficiently rigid and geometrically accurate.
INA roller bearings are units comprising INA roller and cage assemblies and axial bearing washers with a centring spigot. They can be combined with drawn cup needle roller bearings and needle roller bearings. The axial running surface for the needle roller and cage assembly must be hardened and ground.
