Orkot TXMM bearings were chosen for use on a deep ocean submarine installation. The TXMM bearing reportedly exhibits negligible swell in water, therefore maintaining the correct installed operating clearances needed to retain dimensional stability and deliver a long wear life at submarine operating depths. TXMM can be used for special spherical bearing applications and is maintenance free. It has approval for hatch cover slide pads operating dry at pressures up to 35N/mm2. It also has classification approvals from all major societies for totally dry operation, such as neck bearings for ship's rudders. Renk won a contract on the main reduction gear for a new generation of fast ferry design, a 127-m long trimaran introduced by Austal for Fred Olson SA.
