Small, Strong and Smart: Direct drive bearing for antennas

Advantages: small mounting space, high rigidity, integrated direct drive

The Task: A radar antenna should be moved by motor. The antenna rests on the telescopic boom of an off -road vehicle. To avoid obstacles when sending and receiving, the antenna can be raised several meters. The transmission of the rotary drive must participate in this height adjustment.

The Solution: Franke light-weight bearing type LD-Drive with integrated motor. The drive is integrated in the bearing. This eliminates further drive elements such as toothed belts or drive shafts. Only the wiring has to be guided downwards through the telescopic tube.
