Metal Work ISO 15552 cylinder Series has been expanded with the addition of two new piston rod gaskets suitable for use in hostile environments.
The first type, called HARD PU and distinguishable by the final letter "R" in the cylinder code, is made of hard polyurethane (58 Sh D). This gasket is suitable for use in medium-heavy duty applications, with the presence of dirt and low temperatures, such as in agriculture or in the transport sector. This type of gasket leads to an increase in sliding friction, therefore the single-acting or no stick-slip grease versions are not offered. The cylinders that mount this type of scraper are offered with the other gaskets made of polyurethane (from ø32 to ø125) and NBR (for ø160 and ø200).
For the ones who need a greater scraping effect we have also introduced the METAL version, distinguishable by the final letter "M" in the cylinder code, characterized by the presence of a specially designed metallic scraping element. This gasket is suitable for use in heavy duty applications, with the presence of hard dirt and high temperatures, for example in cement factories, foundries or transport sector. The cylinders mounting this type of scraper are offered with the other gaskets made of FKM / FPM.
