Single and double laminar sealing rings FK 5<\/p>\n\t\t\t\t\t

The rings are used to seal roller and plain bearing units on the roller tables of continuous casting plants, industrial steam turbines, mobile and stationary engines. They can be used practically anywhere where extreme operating conditions place higher demands on the sealing system. <\/p>\n\t\t\t\t\t

This includes, for example, corrosion and media resistance of the ring material, high operating temperatures and a high degree of contamination.<\/p>\n\t\t\n<\/div>\n
