Bearing 42412KM from Russia

Single row deep groove roller bearings with short cylindrical rollers are designed to support radial loads and have significantly greater 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 lubricant.
Due to the relatively low friction, the bearings allow a relatively high speed of rotation, although they are inferior in this parameter to ball bearings.
