Advanced bearing material used in new submarine application

Having proven their superior mechanical and physical properties, and maintenance-free reliability in a harsh sea environment, Orkot TXMM bearings were selected for us e on a deep ocean submarine installation. Tests carried out by consultants on behalf of the customer, dem onstrated the bearing material's ability to operate smoothly without stick-slip in an abrasive application. Unlike many othe r non-metallic bearing materials, Orkot TXMM bearings exhibits negligible swell in water and therefore maintains the correct installed operating clearances needed to retain dimensional stabi lity and deliver a long wear life at submarine operating depths The TXMM bearing material incorporates a low-friction wear surf ace and solid lubricants that great ly reduces the coefficient of friction. Its elastic properties allow for bearing deformation under heavy loads or misalignment, which distributes the load ov er a larger contact area thus reduci ng the bearing contact stress. Sleeve and stave bearings used in submarine systems are permanently immersed in seawater and inaccessible for regular maintenance. The Orkot Marine bearings proved ideal for the app lication, plus the ability to handle extreme bearing loading. Having exhibited excellent bearing properties as a water lubricated stern tube bracke t bearing for other applications, TXMM is capable of operating at low velocities with minimal water flow on both bronze and Inconel liner surfaces. TXMM can be used for special spherical bear ing applications and is maintenance-free . It has approval for hatch cover slide pads operating dry at pressures up to 35N/mm². It also has Cla ssification approvals from all major societies for totally dry operation, such as neck bearings for ships' rudders.
