RAILKO NF21 and NF22 grades are resin bonded composite structures with added friction modifiers to give a controlled friction. NF materials are vibration-absorbing bearing grades offering low friction and wear rates.
Railko NF has been developed as a high performance wearing and bearing material for many industrial applications offering low wear and friction rates. Railko NF21 and NF22 are widely used in railway, pump marine and industrial engineering applications. NF21 and NF22 are of the same formulation. NF21 is supplied in flat form with NF22 produced in cylindrical formats.
