The Poolwonder pool cleaner makes cleaning pools in the winter months easy, but requires ball bearings that can withstand constant underwater operation. xiros ball bearings were used for their corrosion-resistance and maintenance-free operation.

Students at the Polytechnic University of Turin designed racing sailboats that required plain bearings, rod ends, and lead screws from igus that could both withstand dynamic movements and resist corrosion and damage from saltwater.

In order to design an underwater torque tool that could operate in sea water, design engineering company Rovtech used iglide plastic bearings. Other alternatives such as bronze would have been too expensive, too heavy, and required lubrication.
