Power transmission

The purpose of the power transmission industry is to generate energy and move it to a location where it can be applied for productive work. Gearboxes are the most common devices for the transmission of movement. In industry, gearboxes are used to transform the speeds and torques produced by the prime mover so that they are suitable to the machine to be driven. RKB provides the players of this sector with extremely durable rolling bearings that optimize energy transmission while increasing reliability.
