UTL Conical Lock Systems In order for the Turkish machine manufacturer to compete with the machine manufacturers of other countries in the world machine market, they will only be able to achieve the same quality. For this reason, elite machine manufacturers, engineers and technicians who closely follow technology, as well as many elite industrial organizations, have started using the UTL Conical Lock System by renovating their machines and abandoning old systems. UTL plays a very important role in the fixing of power transmission organs (gear, pulley, coupling, flywheel) in machine production. In advanced industrialized countries, traditional fixing systems (hidden wedge, tangential wedge, sliding wedge, etc.) have been abandoned in favor of much more successful and superior conical locking systems that have been widely accepted by everyone.
