Slewing bearings and drives by Liebherr contribute to the exploration of the universe

Liebherr's components product segment and mtex antenna technology join forces to provide the antennas for the next generation Very Large Array antennas (ngVLA), which will offer a glimpse into the infinite space reach. The ngVLA will be the largest radio astronomy facility in the Northern Hemisphere. The azimuth adjustment of the antennas is made possible by three-row roller bearings with a diameter of three metres and perfectly matched slewing drives. In addition, gear ring segments together with the drives ensure accurate elevation adjustment of the antenna. The perfect interaction of slewing bearings and drives guarantees precise control and positioning of the antennas for the exploration of the universe.
