Orkot® Marine Bearings - TLM Marine & TXM Marine
Orkot® Marine Bearings, manufactured and developed by Trelleborg, are the world’s leading composite bearings for the shipping and marine industries.More than 30 years of expertise in marine bearings
Orkot® Marine Bearings are manufactured from a unique synthetic composite incorporating solid lubricants to ensure outstanding wear life.
With virtually no swelling in seawater and a very low thermal coefficient of expansion, the bearings provide dimensional stability in arctic and tropical seas.
In addition, they do not corrode or promote corrosion of the housing and shaft and tolerate both edge loading and misalignment.
Orkot® TLM Marine
Orkot® TLM Marine is an advanced, reinforced polymer material incorporating solid lubricants. The material has exceptional wear resistance and virtually no swell in water, providing dimensional stability. Orkot® TLM Marine tolerates edge loading and misalignment even with the heaviest loads. Orkot® Marine Bearings are installed with an interference fit. Bearings are normally freeze fitted using liquid nitrogen but can be press fitted or resin chocked as required. Where there are extended periods without lubrication, such as upper pintle bearings under light ballast conditions.
Orkot® TXM Marine
Orkot® TXM Marine is an advanced reinforced medium weave polymer material (sometimes called synthetic polymer alloy) using a unique manufacturing process that provides a high concentration of PTFE in the sliding area while maintaining high compressive strength. The PTFE layer is several millimeters thick, making it tolerant to wear, while maintaining its low friction properties throughout the service life of the bearing. The PTFE layer is backed by our well known polymer, Orkot® TLM Marine giving a truly homogeneous bearing material without a metal backing layer. In areas where the running conditions are dry, Orkot® TXM Marine has proved particularly effective in eliminating stick-slip problems normally associated with these operating parameters.
