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.

It is capable of withstanding high side loads, damping vibrations and embedded foreign particles. Higher static loads are permissible.

Special materials are available with operating temperatures up to +250 °C / +482 °F. APPLICATIONS: hydraulics, general purpose, standard cylinders, mobile hydraulics
