As ground handling equipment, the air bridge extends from the boarding gate to the aircraft cabin door, which facilitates the passengers to enter and exit the cabin.

However, in the process of use, the air bridge is easy to shake and make noise. That not only affects the safety and comfort of the personnel but also affects the service time of the equipment.

Slewing bearings are applied to aircraft corridor bridges, which can accurately locate while fixing and stabilizing the role of the equipment. As the good damping performance of slewing bearing, it can effectively reduce noise pollution.

Leonessa slewing bearings are characterized by small free clearance and wear resistance. Leonessa controls the best slewing bearing clearance by grinding the raceway and adopting various specifications of steel balls of the same series, which also ensures the slewing bearing rotates more smoothly and steadily so that the slewing bearings can greatly reduce the abnormal wear and tear in the process of long-term use, and prolong the service life of the aircraft corridor bridge.
