RAILKO RG22 is a synthetic fibre reinforced material with added friction modifiers. Fully approved as a rudder bearing material with all major marine classification societies, it contains special friction modifiers permitting its use in dry running applications.
RG22 has very low stick slip which provides smooth operation and testing to DNV specification has shown it to give the longest wear life when compared to other composite materials, rubber and bronze.
RAILKO RG22 can be pressed into housings or freeze-fitted using liquid nitrogen. Bearings can be produced for shafts up to 1000mm diameter and typically with 6 mm allowances on the diameter and 50mm on length to allow for machining at shipyards.
