Radial roller bearings with short cylindrical rollers are designed to support radial loads and have significantly higher radial load-carrying capacity and rigidity than ball bearings due to low elastic deformation.
Bearings with flanges on the outer and inner rings can also support a certain axial load, the magnitude of which depends on the shape of the sliding surfaces of the roller face and flange and, mainly, on the lubrication.
Due to the relatively low friction, the bearings allow relatively high rotational speeds, although they are inferior to ball bearings in this respect.
Field of application: rigid short two-point shafts of machines and mechanisms of various branches of mechanical engineering (aviation, railway (including in the beeches of freight and passenger cars), agricultural, automotive, etc.).
