It consists of a washer-shaped raceway (shaft ring, race) and a cylindrical roller and cage assembly. The cylindrical roller is processed by convex surface, so the pressure distribution between the roller and the raceway surface is uniform, and it can withstand one-way axial load, and the axial load capacity is large, and the axial rigidity is also strong.
Mainly applicable cage: copper alloy cutting cage.
Main uses: oil drilling rigs, iron making steel machinery.
