Marine bearings run continuously unlubricated

Orkot Marine Bearings will introduce Trelleborg Group partners Busak + Shamban Norge and Trelleborg Industri on shared Stand B01-31 at Norshipping this year and featuring the low-friction TXM Marine grade bearing material that can run continuously unlubricated, as well as the classic TLM composite material, approved by all the main classification societies for use as rudder bearings and water lubricated stern tube bearings. The latest options for greaseless operation are included in the TLM approvals and it is typically now approved for 10 or even 15N/mm2 bearing pressure, which is three times the pressure for traditional bearing materials. The TXMM range of marine bearings combines strength and great wear characteristics with very low friction, being made from exceptionally strong medium weave fabrics and having a unique bearing surface incorporating a high concentration of PTFE. It can eliminate stick-slip problems in many applications. These self-lubricating bearings can run completely dry, giving environmental as well as maintenance advantages by eliminating the need for grease. Elastic properties allow for bearing deformation under heavy loads or misalignment. TXMM was specified for the control surface bearings on the US Navy's new Virginia Class submarine and Orkot is the only approved supplier for stern shaft, rudder and stabiliser bearings and SKF coupling covers for the new Royal Navy Type 45 Frigate. The company's extensive stocks and a global network of distributors ensure availability of bearings within 24h. Engineers will provide technical assistance in selecting the best bearing material for improved service life in marine applications including rudders, stern shafts, stabilisers, mooring systems and deck machinery.
