FEROFORM F21 and Railko NF grades are used extensively in railway applications where good wear resistance in dusty and aggressive environments is required, and where they demonstrate the advantages of long life and low friction.

Typical applications for FEROFORM F21 and Railko NF include centre pivot liners, side bearer liners, brake linkage bushes, and friction damper bushes.

Railko JLX grade has PTFE surface layer integrally moulded to a backing material. This gives a low friction working surface free from stick slip combined with good load bearing capability which is used for air spring pads and slide pads.
