I cannot speak for your particular radar, but the ubiquitous E190/290 used in C130, Jetstream, Dominie and lots of other UK military FW aircraft had a notoriously fragile scanner gearbox. GB casings cracked with monotonous regularly. In the horizontal plane, much depends on the scanner controller and how hard it is allowed to bang against the end stops. In the vertical plane, as bellboy says, it may depend on the yoke. I'd phone the radar manufacturer. They'll have installation and use instructions specific to aircraft types.
