Abstract
A roller bearing includes an outer ring having a raceway formed on its inner periphery, a plurality of rollers arranged along the raceway at predetermined intervals, and a solid lubricant filling the spaces between the adjacent rollers. The rollers and the solid lubricant form a one-piece body. The problems of large friction between rollers and the skewing of rollers are solved and it is possible to increase the load-bearing capacity of the bearing by using a large number of longer rollers.
