Trelleborg Sealing Solutions is the sole manufacturer of Orkot® Marine Bearings. These are synthetic composite bearings used in shipbuilding for rudders and water lubricated stern tube bearings, amongst many other applications. They are available through a global network of distributors supporting the shipbuilding and ship repair markets.
Rudder and water lubricated mainshaft bearings
We have a team of experienced engineers who are available to assist you in designing the correct solution to your bearing problem and to help you with optimising performance, reducing total costs, improving service life and solving your delivery and breakdown problems.
Orkot Marine Bearings can be found in the following applications:
- Rudder bearings can be found on thousands of ships around the world. They are fitted as standard by all the leading shipyards for their long service life, ease of fitting and reliability.
Synthetic composite bearings
Orkot synthetic composite bearings have virtually zero swell in water together with a low friction and high load capability, making them the ideal choice for marine bearings. Two materials are available for marine applications, both offering good wear resistance under heavy loads.
Orkot TLMM bearing material
This is the standard marine material grade with a woven cloth reinforcement, solid lubricants and a thermoset resin matrix. The material is equally happy in water or with oil or grease lubrication. It offers the following advantages:
- Almost zero swell in water
- Tolerant to edge loading
- Accepts misalignment of shafts
- Highly resistant to wear
- Can be easily freeze fitted without becoming brittle
Orkot TXMM bearing material
This is a development of the Orkot TLMM bearing material. It uses a special low friction bearing surface to give a very stable bearing and maintain the high load capacity of TLMM whilst offering the benefit of even lower friction and reduced wear. Like TLMM it has the ability to be installed by freeze fitting and can accept shaft misalignment.
This material is used for dry running rudders such as gas carriers and for water lubricated main shaft bearings. It can also be found in our hatch cover pads where the low friction and high load capability are ideally suited to large box ships.
