Solution
For the bearing products in the aircraft, those responsible opted for
iglidur plain bearings. Specifically, plain bearings of the GFM-6065-50 and GSM-9095-100 models are used in the rear suspension struts on the undercarriage. The GE8FO / GEG8ES plain bearings are used in the ball and socket joints of the rudder bearings. The decision was made to use
drylin linear guides in the control rotor. Specifically, the WS 16 single rail is used here together with WJ 200 UM-01-16 bearing housings.
In control processes, the use of plastic hinges and guides with plain bearings is a breakthrough and innovation. The use of iglidur polymer bearings in torsion springs in carbon fibre shins is also a kind of innovation and a solution that requires no maintenance during use and lubrication.
Overall, the replacement with lighter elements that work lubrication and maintenance-free and are not affected by corrosion makes the solution cheaper and reduces utilisation costs.
